interconnects devices in the field across a network. Fieldbus devices are smart and can maintain control over the system. The network can carry many process variables as well as other operational/maintenance information. 1900 m (6234 feet) maximum PC Power Conditioner Terminator Power Supply Control Room Terminator Input Power Input Power Input Power Typical Fieldbus Installation The Enhanced Model TA2 transmitter is a FOUNDATION fieldbus™ registered device that communicates with the H1 FOUNDATION fieldbus™ protocol operating at 31.25 kbits/sec. The H1 physical layer is an approved IEC 61158 standard. An IEC 61158 shielded twisted pair wire segment can be as long as 1900 m (6234 feet) without a repeater. Up to 4 repeaters per segment can be used to extend the distance. The maximum number of devices allowed on a Fieldbus segment is 32. Details regarding cable specifications, grounding, termination, and other network information can be found in IEC 61158 or the wiring installation application guide AG-140 at www.fieldbus.org. NOTE: The Model TA2 FF Flow Meter is designed as a “Four-Wire” Transmitter. Since power is required for the operation, the TA2 FF requires supplemental power which can be either 15 to 30 VDC or 100 – 264 VAC. The TA2 connection to the host computer can be installed using a single pair of wires in multidrop configuration. 4 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 1.2 Device Configuration The function of a FOUNDATION fieldbus™ device is determined by the arrangement of a system of blocks defined by the Fieldbus Foundation. The types of blocks used in a typical User Application are described as follows: Resource Block describes the characteristics of the FOUNDATION fieldbus™ device such as the device name, manufacturer, and serial number. Transducer Blocks contain information such as calibration parameters and sensor type. They are used to connect the sensor to the input function blocks. Function Blocks are built into the FOUNDATION fieldbus™ devices as needed to provide the desired control system behavior. The input and output parameters of function blocks can be linked over the Fieldbus. There can be numerous function blocks in a single User Application. PID Blocks are key to many control schemes and contain the logic necessary to perform Proportional/Integral/Derivative control. Analog Input (AI) Blocks use values from the Transducer Block and make available to other function blocks. Integrator Blocks accumulate the flow or mass value from the AI Block to provide the value of the Totalized Flow. Device Descriptions An important requirement of Fieldbus devices is the interoperability concept mentioned earlier. Device Description (DD) technology is used to achieve this interoperability. The DD provides extended descriptions for each object and provides pertinent information needed by the host system. Any Fieldbus host system can operate with a device if it has the proper DD and Common File Format (CFF) for that device. The most recent DD and CFF files can be found on the FOUNDATION fieldbus™ web site at www.fieldbus.org. NOTE: Please consult your host system vendor for any host-specific files that may be needed. 1.2.1 FOundATIOn fieldbus™ Revision Table Model TA2 2.x FOundATIOn fieldbus™ FOundATIOn fieldbus™ Version Release date Compatible with TA2 Software Dev V1 DD V1 Version 2.0A and later 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ October 2011 5 1.3 Link Active Scheduler (LAS) The default operating class of the Enhanced Model TA2 with FOUNDATION fieldbus™ is a basic device. However, it is capable of being a Link Active Scheduler (LAS). The LAS controls all communication on a FOUNDATION fieldbus™ segment. It maintains the “Live List” of all devices on a segment, coordinates both the cyclic and acyclic timing and, at any given time, controls which device publishes data via Compel data (CD) and Pass Token (PT). The primary LAS is usually maintained in the host system, but in the event of a failure, all associated control can be transferred to a backup LAS in a field device such as the Enhanced Model TA2. The operating class can be changed from basic to LAS using a FOUNDATION fieldbus™ configuration tool. NOTE: The Enhanced Model TA2 is shipped from the factory with Device Class set to Basic. 2.0 Quick Start Installation The TA2 is calibrated and configured with the information supplied to MAGNETROL with the order. The instrument can be installed, wired, and placed directly into operation. 2.1 Probe Installation Insert the probe into the pipe or duct at the appropriate location. It is recommended that the sensor be located on the center line of the pipe and that the flow arrow be positioned in the direction of flow. See Appendix B for recommended straight run and flow conditioning plate installation details (if applicable). Pipe centerline 25 mm (1") Figure 1 Probe Installation into Pipe or duct using a Compression Fitting 6 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 2.2 Wiring Warning: Explosion Hazard. Do not connect or disconnect equipment unless power has been switched off or the area is known to be non-hazardous. NOTE: Make sure the electrical wiring to the TA2 is complete and in compliance with all regulations and codes. For a maximum ambient temperature of 80 °C use wiring rated up to 264 VAC and 105 °C. For a maximum ambient temperature of 70 °C use wiring rated up to 264 VAC and 95 °C. AC Power input (100 – 264 VAC) TB1 INPUT AC L2 L1 100-264 VAC 50/ 60Hz DC Power input (15 – 30 VDC) TB2 FOUNDATION fieldbus™ Connection TB3 DC INPUT FIELDBUS INTERFACE + FF– FF+ – TB2 NOTE: The AC power terminal blocks accept 12-22 AWG wire and the DC power terminal blocks accept 14-30 AWG wire. Select wire size consistent with power requirements. 1. Remove the cover of the rear compartment. 2. Pull power supply and control wiring through conduit connection. 3. Connect power leads to proper terminals. a. 100 to 264 VAC – Make connections to TB1. Connect the “hot” wire to L1 and the second wire to L2. b. 15 to 30 VDC – Make the connections to TB2. Connect the Positive wire to (+) and the negative lead to (–). 4. Connect Foundation fieldbus leads to terminal TB3. Connect the positive wire to FF+ and the negative wire to FF-. Fieldbus voltage range is 9-32 VDC. TB3 TB1 Figure 2 Enhanced TA2 FOundATIOn fieldbus ™ Wiring Board NOTE: Ensure that the correct wiring is made to the appropriate terminals. Connecting the DC power to the AC terminals will cause the unit not to operate. Connecting the AC power to the DC terminals will blow the fuse and potentially cause damage to the electronics boards. NOTE: The green ground screw in the rear of the housing should be used for earth ground. NOTE: Shielded cable is required for the DC wiring. Connect the shield wire to the green ground screw in the rear of the housing. 2.3 Configuration The TA2 is pre-configured using the information supplied with the order. If desired, the user can view or change any of the configuration data. See Configuring the Transmitter, Section 3.5 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 7 3.0 Installation 3.1 Unpacking Save the Calibration Certificate containing the calibration and configuration data for future reference. 3.2 Electrostatic Discharge (ESD) Handling Procedure 1. 2. 3. 4. MAGNETROL electronic instruments are manufactured to the highest quality standards. These instruments utilize electronic components which may be damaged by static electricity present in most work environments. The following steps are recommended to reduce the risk of component failure due to electrostatic discharge: Ship and store circuit boards in anti-static bags. If an antistatic bag is not available, wrap board in aluminum foil. Do not place boards on foam packing materials. Use a grounding wrist strap when installing and removing circuit boards. A grounded workstation is also recommended. Handle printed circuit boards only by the edges. Do not touch components or connector pins. Ensure that all electrical connections are completely secure and none are partial or floating. Ground all equipment to a good earth ground. NOTE: The instrument is rated per IEC 61010-1 for use in Installation Category II, Pollution Degree 2. 8 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 3.3 Installation 3.3.1 Electronics The instrument is rated for use in Class I, Division 1 and Class I, Division 2 areas. The enclosure is also rated NEMA 4X. Remote electronics (optional) should be installed in an easy to access location within 150 m (500 feet) of the sensor. The electronics should not be installed in areas where ambient temperature exceeds +80 °C (+175 °F). If ambient temperature is between -30 °C to -54 °C (-22 °F to -65 °F), the unit will operate but the display will not be readable. Provide watertight seals for all wiring entrances in the enclosure to maintain the NEMA 4X rating. Use appropriate NEC section when installing the instrument. NOTE: A switch or circuit breaker should be installed in close proximity to the equipment and within easy reach of the operator. It should be marked as the disconnecting device for the equipment. 3.3.2 Probe/Flow Body Pipe centerline 25 mm (1") Figure 3 Probe Installation into Pipe or duct using a Compression Fitting Proper installation of the probe in the pipe or duct is essential for accurate air or gas flow measurement. Normal procedures for installing any type of flow element should be followed. See Appendix B for additional information on probe location. A flow arrow is etched on the sides of the probe to designate flow direction. The instrument is calibrated with the flow in this direction. Ensure that the flow arrow is aligned in the direction of flow. The instrument is unable to recognize flow direction if inserted with the flow arrow in the wrong direction. It is generally recommended that the sensor be located in the center of the pipe. This location provides less sensitivity to changes in flow profile. Sensors mounted through compression fittings have the ability to field adjust the sensor to the desired location by using the dimensions as shown in Figure 3. It may be necessary to rotate the head of the instrument to view the display while maintaining the proper flow orientation. This is accomplished by loosening the set screw on the bottom of the housing, rotating the enclosure to the desired position and re-tightening the set screw. The second set screw is a stop to prevent over rotating the enclosure. See figure 4. Figure 4 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 9 Various methods of mounting the probe include compression fittings, threads, and flanged connections. Refer to probe model numbers. The insertion probe can be installed through a compression fitting. The use of a bored-through fitting with 3⁄4" or 1" NPT connection for 3 ⁄4" outside diameter tube is recommended. The use of Teflon® ferrules should be considered if repeated reposition of the sensor is considered. The stainless steel ferule can only be tightened once as it makes a permanent indentation on the probe. If using a compression fitting with stainless steel ferrules, ensure that the probe is in the desired location before tightening. NOTE: The TA2 flow measurement is based on a fully developed turbulent flow profile in a pipe with the specified inner diameter. Accuracy will be affected if these conditions are not obtained. Installing the probe in a tee is not recommended as the flow profile and the flow area are distorted (See figure 5). For applications where it is desirable to install or remove the probe without having to shut down the process, The MAGNETROL Retractable Probe Assembly (RPA) can be utilized. WARNING To avoid potential damage or injury, never loosen a compression fitting while sensor is under pressure. Figure 5 Probe Installation into a Tee Fitting is not Recommended NOTE: Remote electronics is recommended for operating temperatures greater than +120 °C (+250 °F) or in locations where the temperature of the electronics will exceed +80 °C (+175 °F). Optionally, an insertion probe with extended probe length to provide at least 100 mm (four inches) between the electronics and the compression fitting can be utilized. NOTE: The sensor must be installed in a location where moisture cannot drip or come in contact with the heated element. Any contact with condensed moisture in the gas flow will cause a false high flow indication. Consider mounting the probe at a 45° angle from top, from the side or bottom of the pipe to minimize possibility of condensed moisture running down the probe and contacting the sensor (see Figure 6). In extreme cases, it may be necessary to insulate or even heat trace the pipe to prevent the condensation of moisture. The TA2 with an insertion probe provides a point measurement and assumes that a fully developed profile exists. See Appendix B. The user has the ability to compensate the flow measurements based upon flow profile considerations under the Advanced Configuration section of the software. See Section 3.5.9. Figure 6 Install the TA2 at an Angle where Condensed Moisture may be Present 10 NOTE: If equipment is used in a manner not specified by manufacturer, protection provided by equipment may be impaired. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 3.4 Wiring There are two connections in the electronics enclosure for 3 ⁄4" NPT or M20 connections. These are generally used as one connection for input power and one for output signal. 3.4.1 Power and Signal Connection Front Compartment The instrument has separate wiring connections for AC (100 to 264 VAC) and DC (15 to 30 VDC). AC power wiring connections are made to terminal block TB1. DC Connec-tions are made to terminal block TB2. Refer to Figure 8. Rear Compartment NOTE: The AC power terminal blocks accept 12-22 AWG wire and the DC power terminal blocks accept 14-30 AWG wire. Select wire size consistent with power requirements. For a maximum ambient temperature of 80 °C use wiring rated up to 264 VAC and 105 °C. For a maximum ambient of 70 °C use wire rated up to 264 VAC and 95 °C.

Figure 8 Enhanced TA2 FOundATIOn fieldbus ™ Wiring Board Caution: In hazardous areas, do not apply power to the unit until the conduit is sealed and the enclosure cover is screwed down securely. NOTE: Install using Teflon® tape at all conduit entries (maximum 2 turns). 3.4.2 Ground Connection The instrument must be grounded in accordance with Article 250 of the National Electric Code. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 11 3.4.3 Remote Electronics Power Fieldbus Board in Electronics Housing 1 If the electronics are remote from the probe, a remote board with terminal blocks is provided in the housing on the probe. In case of ATEX flameproof enclosure a special 8-conductor shielded cable is used. Refer to cable model numbers. For non-hazardous area the type of cable depends on the required length. For cable lengths up to 45 m (148 ft), the connection between the probe and electronics should be an 8-conductor shielded cable (Belden 8104). For cable lengths up to 150 m (492 ft), a 10-conductor shielded cable (Belden 8305) is used. Refer to cable model numbers. This cable length can be adjusted in the field. If cable other than the recommended Belden cable is used, following are the maximum resistances which should be utilized: 2 4 5 0 1 91 TB 7 8 6 3 11 J1 8 Conductor –maximum resistance of 5.4 ohms 10 Conductor –maximum resistance of 10.0 ohms Caution: The probe and electronics are calibrated and shipped as a matched set.

Configuration information on the totalizers is found on page 23. Damping Increasing the Damping will smooth the TA2 display of the measured values. This may be used in cases when turbulence is causing fluctuations in the measurement. The damping value is expressed in time constants. A one-second time constant means that with a step change in flow, the measured flow value will reach approximately 63 % of the new value in one second and approximately 99 % of the new value in five seconds. The lower limit is 0 which means no damping (other than the inherent response time of the sensor); the upper limit is 15 seconds. 3.5.8 Totalizer The totalizer provides seven digits of resolution. In the event of a fault indication, the totalizer will not accumulate. When the value in the totalizer exceeds 9,999,999, the totalizer will rollover. The Total Time will keep counting. Both the Resettable and Non-Resettable totalizers have individual multiplier factors which can be used to prevent too frequent rollover and potential loss of data. The Totalizer data is stored in nonvolatile memory, eliminating the need of backup batteries. Data is written hourly. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 21 UP–DN Totalizers to select R Total Mode [selection] ENT DEL ENT DEL UP–DN R Total Units [selection] DEL ENT DEL Disabled Enabled SCF Nm3 Nl lb kg UP–DN R Total Mult [selection] DEL ENT DEL UP–DN 1 10 100 1,000 10,000 100,000 R Totalizer nnnnnnn units DEL UP–DN DEL R Total Time nnnnnh nnm nns UP–DN R Totalizer Reset DEL ENT DEL UP–DN NR Total Units [selection] DEL ENT DEL Are You Sure?

The idea of Function Blocks, which a user can customize for a particular application, is a key concept of Fieldbus topology. Function Blocks consist of an algorithm, inputs and outputs, and a userdefined name. The RESOURCE Block contains specific information on the Enhanced TA2 and firmware. The TRANSDUCER Block output is available to the network through the ANALOG INPUT blocks. The ANALOG INPUT Blocks (AI) take the TRANSDUCER Block measured values and makes them available as an analog value to other function blocks. The AI blocks have scaling conversion, filtering, and alarm functions. The INTEGRATOR Block will accumulate the flow or mass over time providing a value of the Totalized Flow. The PID Block provides logic for Proportional/Integral/Derivative control. 4.1.1 universal FOundATIOn fieldbus™ Block Parameters The following are general descriptions of the parameters common to all blocks. Additional information for a given parameter is described later in that specific block section. ST_REV (static data revision): a read only parameter that gives the revision level of the static data associated with the block. This parameter will be incremented each time a static parameter attribute value is written and is a vehicle for tracking changes in static parameter attributes. TAG_DESC (tag descriptor): a user assigned parameter that describes the intended application of any given block. STRATEGY: a user assigned parameter that identifies groupings of blocks associated with a given network connection or control scheme. ALERT_KEY: a user assigned parameter which may be used in sorting alarms or events generated by a block. MODE_BLK: a structured parameter composed of the actual mode, the target mode, the permitted mode(s), and the normal mode of operation of a block. • The actual mode is set by the block during its execution to reflect the mode used during execution. • The target mode may be set and monitored through the mode parameter. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 35 • The permitted modes are listed for each block. • The block must be in an automatic mode for normal operation. NOTE: The MODE_BLK target parameter must be OOS (out of service) to change configuration and calibration parameters in that function block (when in OOS, the normal algorithm is no longer executed and any outstanding alarms are cleared). All blocks must be in an operating mode for the device to operate. This requires the Resource Block to be in “AUTO” and the Transducer Block to be in “AUTO” before the Function Blocks can be placed in a mode other than OOS (out of service). BLOCK_ERR: a parameter that reflects the error status of hardware or software components associated with, and directly affecting, the correct operation of a block. NOTE: A BLOCK_ERR of “Simulation Active” in the Resource Block does not mean simulation is active—it merely indicates that the simulation (hardware) enabling jumper is present. See section 4.2.2 and 5.1 for further information on the simulation mode. 4.2 Resource Block The RESOURCE Block contains data specific to the Enhanced Model TA2 transmitter, along with some information about the firmware. NOTE: The Resource Block has no control function. MODE_BLK: Must be in AUTO in order for the remaining blocks in the transmitter to operate. NOTE: A Resource Block in “out of service” mode will stop all function block execution in the transmitter. RS_STATE (Resource State): identifies the state of the RESOURCE Block state machine. Under normal operating conditions, it should be “On-Line.” TEST_RW: Read/Write test parameter used for conformance testing. DD_RESOURCE: a string identifying the tag of the resource that contains the Device Description for this device. MANUFAC_ID: contains the MAGNETROL INTERNATIONAL FOUNDATION fieldbus™ manufacturer’s ID number, which is 0x000156. DEV_TYPE: the model number of the THERMATEL Enhanced Model TA2 transmitter (0x0004). It is used by interface devices to locate the Device Descriptor (DD) file for this product. DEV_REV: contains the device revision of the THERMATEL Enhanced Model TA2 transmitter. It is used by interface devices to correctly select the associated DD. 36 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ DD_REV: contains the revision of the DD associated with the version of firmware in the THERMATEL Enhanced Model TA2 transmitter. It is used by interface devices to correctly select the associated DD. GRANT_DENY: Options for access to parameters by DCS. HARD_TYPES: Types of hardware available as channels. RESTART: Default and Processor selections are available. Default will reset the Model TA2 to the established block configuration. NOTE: As RESTART DEFAULT will set most block configuration parameters to their default values. Devices need to be reconfigured following activation of this function. FEATURES: a list of the features available in the transmitter. The Model TA2 features include Reports, and Soft Write Lock. FEATURES_SEL: allows the user to turn Features on or off. CYCLE_TYPE: identifies the block execution methods that are available. CYCLE_SEL: allows the user to select the block execution method. MIN_CYCLE_T: the time duration of the shortest cycle interval. It puts a lower limit on the scheduling of the resource. MEMORY_SIZE: Size of available memory in K bytes. NV_CYCLE_T: the minimum time interval between copies of non-volatile (NV) parameters to NV memory. NV memory is only updated if there has been a significant change in the dynamic value and the last value saved will be available for the restart procedure. A value of “0” means it will never be automatically copied. Entries made by human interface devices to NV parameters are copied to non-volatile memory at the time of entry. NOTE: After completing a large copy, allow several seconds before removing power from the THERMATEL Enhanced Model TA2 transmitter to ensure that all data has been saved. FREE_SPACE: shows the amount of available memory for further configuration. The value is zero percent in a preconfigured device. FREE_TIME: the amount of the block processing time that is free to process additional blocks. SHED_RCAS: the time duration at which to give up computer writes to function block RCas locations. Shed from RCas will never happen when SHED_RCAS = 0. SHED_ROUT: the time duration at which to give up computer writes to function block ROut locations. Shed from ROut will never happen when SHED_ROUT = 0. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 37 FAULT_STATE, SET_FSTATE, CLR_FSTATE: these only apply to output function blocks. (The Model TA2 has no output function blocks). MAX_NOTIFY: the maximum number of alert reports that the transmitter can send without getting a confirmation. The user can set the number low, to control alert flooding, by adjusting the LIM_NOTIFY parameter value. LIM_NOTIFY: the maximum numbers of unconfirmed alert notify messages allowed. No alerts are reported if set to zero. CONFIRM_TIME: the time that the transmitter will wait for confirmation of receipt of a report before trying again. Retry will not occur if CONFIRM_TIME = 0. WRITE_LOCK: When set to LOCKED, will prevent any external change to the static or non-volatile data base in the Function Block Application of the transmitter. Block connections and calculation results will proceed normally, but the configuration will be locked. UPDATE_EVT (Update Event): is an alert generated by a write to the static data in the block. BLOCK_ALM (Block Alarm): is used for configuration, hardware, connection, or system problems in the block. The cause of any specific alert is entered in the subcode field. The first alert to become active will set the Active status in the Status attribute. As soon as the Unreported status is cleared by the alert reporting task, another block alert may be reported without clearing the Active status, if the subcode has changed. ALARM_SUM (Alarm Summary): contains the current alert status, the unacknowledged states, the unreported states, and the disabled states of the alarms associated with the block. ACK_OPTION (Acknowledge Option): selects whether alarms associated with the block will be automatically acknowledged. WRITE_PRI (Write Priority): the priority of the alarm generated by clearing the write lock. WRITE ALM (Write Alarm): the alert generated if the write lock parameter is cleared. ITK_VER (ITK Version): contains the version of the Interoperability Test Kit (ITK) used by the Fieldbus Foundation during their interoperability testing. 38 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 4.2.1 Additional Resource Block Parameters Field Diagnostic Parameters FD_VER: Major version of the Field Diagnostic specification to which this device conforms.

It contains the TA2 transmitter configuration, diagnostics, and calibration data. Output from the Transducer Block is process variables and status information. The TRANSDUCER Block parameters are grouped in a useful configuration. There are both read-only parameters and read-write parameters within the TRANSDUCER Block. • The read-only parameters report the block status and operation modes. • The read-write parameters affect the function block basic operation, transmitter operation, and calibration. The Transducer Block will automatically be changed to “Out of Service” when the local interface (keypad) is used to change a parameter online. The Transducer Block must be placed back in service from the Host system. 4.3.1 Transducer Block Parameters The first six parameters in the TRANSDUCER Block are the universal parameters discussed in section 4.1.1. After the universal parameters, six additional parameters are required for Transducer Blocks. The most notable of these parameters are UPDATE_EVT and BLOCK_ALM. It should be noted that these six additional parameters must exist but do not have to be implemented. An important device-specific parameter found later in the TRANSDUCER Block list is DEVICE_STATUS, which displays the status of the device. If more than one message exists, then the messages are displayed in priority order. If DEVICE_STATUS indicates a problem, refer to Section 5.2, Troubleshooting. For a complete list of Transducer Block Parameters, refer to table in the Appendix A - Transducer Block Parameters. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 41 4.4 Analog Input Block The ANALOG INPUT (AI) Block takes the THERMATEL Model TA2 input data, selected by channel number, and makes it available to other function blocks at its output: Channel Process Value 1 Flow 2 Mass 3 Process Temperature 4 R.

LO_LO_ALM: The status for low low alarm and its associated time stamp. The TRANSDUCER and AI Block’s MODE_BLK parameter must be set to AUTO to pass the PV Value through the AI to the network. Transducer scaling, called XD_SCALE, is applied to the PV from the CHANNEL to produce the FIELD_VAL in percent. Selection of valid XD_SCALE engineering units is limited to predefined units of measurement which is dependent on what channel is selected in the AI Block. Options include SCFM, SCFH, MMSCFD, Nm3/h, Nl/h, lb/h, lb/min, kg/h, kg/min, °F, °C, SCF, kg, lb, Nm3, and Nl. 1. 2. 3. 4. The AI blocks can have a BLOCK_ERR when: Channel is not set correctly. XD_SCALE does not have suitable engineering units or has range incompatibility. SIMULATE parameter is active AI Block MODE is O/S (out of service). NOTE: This can be caused by the Resource Block being OOS or the AI Block not scheduled for execution. 5. L-TYPE not set or set to Direct with improper OUT_SCALE. The AI Block uses the STATUS_OPTS setting and the TRANSDUCER PV LIMIT value to modify the AI PV and OUT QUALITY. Damping Filter is a feature of the AI Block. The PV_FTIME parameter is a time constant of a single exponential filter for the PV, in seconds. This parameter can be used to dampen out fluctuation. The AI Block has multiple ALARM functions that monitor the OUT parameter for out of bound conditions. 4.5 PID Block The PID Function Block contains the logic necessary to perform Proportional/Integral/Derivative (PID) control. The block provides filtering, set point limits and rate limits, feedforward support, output limits, error alarms, and mode shedding. Although most other function blocks perform functions specific to the associated device, the PID Block may reside in any device on the network. This includes a valve, a transmitter, or the host itself.

UPDATE_EVT: This alert is generated by any changes to the static data. 4.6 Integrator Block The Integrator Function Block integrates an analog value as a function of the time. The block may be used as a totalizer that counts up until reset, or as a batch totalizer that has a setpoint. When used as a batch totalizer, the integrated value is compared to pre-trip and trip settings to generate discrete signals when these settings are reached. The Integrator Block has two inputs, and can only get an input value from another function block, typically an Analog Input Block. It cannot get an input value directly from the Transducer Block. The Integrator Block and internal totalizer are independent and may have different values. The difference can occur due to different sample times or different reset times. A simple configuration for the Fieldbus Model TA2 might be as follows: • AI Block is configured with channel set to Flow. XD_SCALE, OUT_SCALE, and L_TYPE parameters are set appropriately so that the AI Out value is flow in SCFM. • IT Block is configured as follows: • Set Units Index in OUTPUT_RANGE to SCF. • Select “minutes” for TIME_UNIT1 which corresponds to the rate time unit of the AI Out value. • Select “Demand” for INTEG_TYPE (Count up and is reset on demand; totalizer set point and trip outputs are not used). • Select “Flow forward” for INTEG_OPT. • GOOD_LIM set to 90 %. • UNCERT_LIM set to 75 %. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 47 • Using a Configuration Tool, the OUT value from the AI Block is connected to IN_1 of the Integrator Block, and both function blocks are then scheduled for execution. • If successful, the function blocks can go into service if the Resource Block is in service. Note that the Totalized value in the Integrator Block is saved in non-volatile memory every 60 seconds. In the event that the power is lost, the maximum totalized value lost would correspond to one minute of flow. Also, the IT Out value will be available for display on the local user interface similar to the AI Out Values. 4.6.1 Integrator Block Parameters BLOCK_ALM: Used for all configuration, hardware, connection failure, or system problems in the block.

UPDATE_EVT: This alert is generated by any changes to the static data. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 49 4.7 Local Display of Function Block Values The LCD and keypad on the Model TA2 Foundation Fieldbus transmitter provides access to read or change the Transducer Block parameters. In addition the TA2 permits the display of the devices Analog Input [AI] Block and the Integrator [IT] Block output values on the local LCD under Measured Values. These values can be displayed on the rotating display—see section 3.5.5. A list of the Analog Input Block Process values is shown in section 4.4. Typical display of the Analog Output values is shown in figure 11. AI Block # AI Block Channel Process Value * AI# Out-mmmm * #########uuuuu Out Value Out Scale units abbreviation Figure 11 The screens will be formatted as shown, where # in the title is the number of the AI Block (1, 2, 3, 4, or 5) and mmmm is one of: “Flow”, “Mass”, “Temp”, “NRTot”, “RTot”, “----” depending on the value of the associated AI Block’s Channel parameter. • For example, “AI1 Out-Flow” will probably be the most commonly used AI Out screen • “AI2 Out----” would be displayed when the channel value is 0 [uninitialized] for AI Block 2. Additional representative examples are shown in figure 12. * AI1 Out-Flow * 10.0 % * AI1 Out-Mass * 20.0 lb/min * AI2 Out-Temp * 50.00 °C * AI5 Out - - - - * * AI4 Out-NRTot * 10000 lb * IT Out * 10000 SCF Figure 12 There may be differences in the AI value in the Analog Input Block and the IT value in the Integrator Block compared to the values shown on the TA2 display. Primary reason for this difference is the time when the data was acquired. In order to provide indication that the Function Block is not executing and/or to avoid displaying a possibly stale value, the second row will be blank if the Block Error parameter in a configured Function Block is indicating Out Of Service, a block configuration error, or input failure. The second row on an AI Out screen or IT Out will also be blank if the unit has not been assigned a permanent address, or if the associated Function Block has not been configured and scheduled for execution. The Out Scale units abbreviations will be displayed only when the Output Scale Units Abbreviation is “%” or one of the flow, mass, temperature, or totalizer units supported for local display. 50 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 5.0 Diagnostic Parameters The Model TA2 measurement engine runs through a series of self-tests and will detect and report faulty operation. The TRANSDUCER BLOCK displays these faults in the DEVICE_STATUS parameter. Refer to Section 5.2.1.4 for more information on specific faults and warnings. BLOCK_ERROR is not used except for indicating Out of Service (OOS). When the Model TA2 is initially powered on, the measurement engine does not have enough valid measurement cycles to make a decision about the output value. For the first few seconds after power is applied, the FLOW_STATUS/QUALITY is “Uncertain,” the SUB_STATUS is “Initial value,” and the LIMIT attribute is “Constant.” When the Model TA2 is operating properly, the FLOW_STATUS/QUALITY is shown as “GOOD,” and the SUB_STATUS is “Non-Specific.” While changing the transmitter operational parameters using the local display or through the system configuration tool (with the MODE_BLK in OOS), the output might be inaccurate because of the changing parameters. When the device is set to OOS, the TRANSDUCER BLOCK will still output flow but the QUALITY will be shown as “Bad” and the SUB_STATUS is “Out of Service.” When the Enhanced Model TA2 measurement cycle fails to find a valid output value, the transmitter maintains the last good value as the output and flags the failure. The LIMIT attribute is the same as the last good measurement. If the Model TA2 fails to find a measurable signal, the TRANSDUCER BLOCK maintains the last good value as the output and flags the failure. The QUALITY is “Bad,” the SUB_STATUS is “Sensor failure” for no flow (or “Device failure.” Refer to Section 5.2.1.4 for additional information. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 51 5.1 Simulation Feature The THERMATEL Model TA2 with FOUNDATION fieldbus™ supports the Simulate feature in the Analog Input Block. The Simulate feature is typically used to exercise the operation of an AI block by simulating a TRANSDUCER block input. U1 U21 U20 This feature cannot be activated without the placement of a hardware jumper. Normally, the THERMATEL Model TA2 will ship with the hardware jumper placed so that the Simulation Feature is disabled. See section 5.1.1 for instructions about accessing the Simulation jumper. J1 U24 Q1 U4 J3 U3 R194 J2 R101 R90 5.1.1 Accessing the Simulation Jumper To access the simulation jumper: 1. Remove the cover to the electronics display. 2. Remove the display module by removing the two retaining screws. 3. To enable simulation, place jumper at J3 across the two pins.To disable simulation, place jumper at J3 on one pin only. P3 J3 Simulation Jumper Figure 13 NOTE: Do not remove the jumper at position J2. The J2 jumper is used in a diagnostic test; see section 5.3.1. 4. Reassemble the display module and cover. NOTE: A BLOCK_ERR of “Simulation Active” in the Resource Block does not mean simulation is active—it merely indicates that the simulation (hardware) jumper is placed to enable simulation. See section 4.2.2 for instructions to mask this block error. 5.2 Troubleshooting The TA2 Thermal Mass Flow Meter is designed for ease of use and trouble-free operation. The TA2 is shipped pre-calibrated and pre-configured based on information provided at time of order. The following lists possible problems and solutions to investigate. WARNING! Explosion hazard. Do not remove the TA2 housing cover unless power has been switched off or the area is known to be non-hazardous. 52 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 5.2 Troubleshooting (cont.) Symptom Problem Solution No Output signal No Display No input power Verify that LED D6 on the input wiring board is on. If not, check wiring connections. Check F1 test and F2 test to check fuses protecting input wiring. See Figure 8. Totalizer not operating Totalizer is Disabled Ensure that the totalizer operation is enabled. See section 3.5.8. Flow is measured under a no flow condition Increased heat transfer. This can occur under no flow with increased pressure. Increase the low flow cutoff to a value greater than the displayed flow rate. The TA2 will ignore readings lower than this value. Optionally, increase the zero flow signal to match the value indicated under Signal Value. See section 3.5.14. Instrument configuration does not match actual application Check values entered for Flow Area under Basic Configuration. Check if Install Factors are entered under Advanced Configuration. Check STP conditions under Advanced Configuration. Buildup on sensor Depending on type and size of buildup, flow readings may either increase or decrease. Clean sensor. Flow Rate too high Flow Profile Considerations The TA2 assumes a specific fully developed flow profile. User can correct for variations in flow profile using the Install Factors found under Advanced Configuration section 3.5.9. Flow Rate too high, output spiking Moisture in the Gas Condensed moisture will cool the sensor more than gas flow. This will temporarily indicate a higher than expected flow rate. Flow Rate too high or too low 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 53 5.2.1 Error Messages The TA2 Mass Flow Meter utilizes a 3-level hierarchy for reporting diagnostics information: FAULTS, WARNINGS, and INFORMATION. Faults and Warnings can be reviewed on the rotating screen in the Home menu. These screens capture only current conditions. Historic diagnostic information can be viewed in the HISTORY screen of the Diagnostics Menu. FAULT: The highest level in the hierarchy of diagnostics. A Fault indicates a defect or failure in the circuitry or software, or a calibration condition that makes reliable measurement impossible. Further error information can be obtained by reviewing the Diagnostic Menu screens. WARNING: This is the second level in the hierarchy of diagnostics. A Warning indicates conditions that are not fatal but may affect the measurement. A message will appear on the Home (rotating) screen when a Warning is detected but will not affect the output current. Further error information can be obtained by reviewing the Diagnostic Menu screens. INFORMATION: This is the lowest level in the hierarchy of diagnostics. Information messages are for conditions that provide operational factors that are not critical to the measurement. Further error information can be obtained by reviewing the Diagnostics Menu. 54 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 5.2.1.1 Fault Messages diagnostic Fault description/Corrective Action LCd Message Non-Volatile Memory corruption Partial corruption of the Non-Volatile memory stored in the EEPROM.

If a static parameter is changed from the local display, the Transducer Block is taken Out of Service if it is not already, and the “Config Changed” mode condition is set in Device Status. This will indicate to the operator that the configuration has been changed from the local display. No indication is given on the Fieldbus network if someone is only viewing parameters on the local display. For the Default Totalizer Warning, PV Status is bad only if the PV is R Totalizer or NR Totalizer. If the PV is Flow, Mass, or Temperature, PV Status is “Good, Non-specific, Not Limited”. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 57 5.3 Diagnostics Test The TA2 has several diagnostics tests which may be routinely performed. When conducting these tests, the Transducer Block is taken Out of Service (OOS). 5.3.1 Heater Setting U1 U21 U20 J1 U24 Q1 U4 J3 U3 R194 J2 P3 R101 R90 The amount of current flowing to the heater is displayed under Diagnostics/Heater Setting. This value can be verified by connecting a multi-meter across the Heater Bypass terminals (J2) shown in figure 13. This board can be accessed by opening the cover and removing the display module. See Figure 14. The measured value should match the value shown on the display. Any difference between the two values indicates that the heater calibration is incorrect. If the heater circuit is open, a nominal current value will be displayed, but the measured current will be zero. 5.3.2 Zero Power Test J2 Heater Test Figure 14 This test checks that the resistances of the RTDs have not changed. The heater is turned off and the temperature difference between the two sensors is compared. The test should be performed in a water bath (preferred) or under flowing conditions. Conducting this test in still air will cause the test to time out and provide inconclusive results. The temperature difference between the two sensors is displayed. Typical values will match within 0.15 °C. Temperature difference may be as high as 0.5 °C depending upon test conditions. If greater than this value, contact the factory as drift in the RTDs may have occurred. 5.3.3 Calibration Verification Procedure The TA2 measures heat transfer. These procedures are designed to permit the user to verify the calibration by checking the heat transfer characteristics of the sensor. If the heat transfer characteristics are approximately the same when the test is conducted compared with when the same data was collected at the factory during the initial calibration, the unit remains in calibration. 58 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ The procedure is performed under two different sets of conditions. Both tests should be conducted at “room temperature,” approximately +21 °C to +30 °C (+70 °F to +85 °F). Low Flow Validate—Simulates a low flow condition. i. Cover sensor tips to isolate from air currents. During the test, the heater power is set and the Delta T (temperature difference) between the two RTDs is measured. ii. After completion of the test, the value of the temperature difference measured during the test is compared against the previously stored value. (This value can also be compared with the initial calibration found on the original calibration certificate.) iii. The value from the test should compare with the stored (or original calibration value) within 1.5 °C. This variation in part due to potential variations of the ambient temperature during the test and differences in test methods. Figure 15 High Flow Validate—Simulates a high flow condition. i. Support the TA2 vertically in a water bath. See Figure 15. During the test, the heater power is set and the Delta T (temperature difference) between the two RTDs is measured. ii. After completion of the test, the value of the temperature difference measured during the test is compared against the stored value. (This value can also be compared with the initial calibration found on the original calibration certificate.) iii. The value from the test should compare with the stored (or original calibration value) within 1.5 °C This variation in part due to potential variations of the ambient temperature during the test and differences in test methods. If the temperature difference measured during the test is greater than the recommended temperature difference indicated above in item “iii”, then the overall accuracy of the TA2 may be affected.

Proceed to section 6.3. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 61 6.3 Replacement Calibration 6.3.1 RTd Calibration If either the probe or the processor board is replaced in the field, calibration of the RTDs in the probe will return the TA2 to like-new performance. NOTE: If this procedure is not followed, the accuracy will be affected; however, very repeatable flow measurements will be obtained. Locate the sensor vertically in a water bath with an accurate temperature sensor directly adjacent to the probe tips. It is preferable that the water is stirred during the calibration to ensure the TA2 pins and temperature probe are at the same temperature. Using the keypad and display, select “Factory Config\Probe Params\Probe Temp Calib” and then press the Enter key. The device will dynamically display the To/Fo readings over a period of time. After 3 minutes, and if the readings are stable enough, the display automatically changes to request entry of a password (126) followed by the ambient water temperature. After the temperature is entered, the device will display if the calibration is OK. The device then automatically resets itself for normal operation. 6.3.2 Set Point Adjustment A new set point must be calculated to complete the reconfiguration. 1. Place the probe in ambient temperature air where there is no flow across the sensor. This can be accomplished by wrapping the sensor tip with a piece of paper. 2. Go into Diagnostics ’ Signal. Allow time for the signal to stabilize to within ±1 mW and record the new signal. 3. Calculate a new set point by using the following formula: New set point = set point x (zero flow signal ÷ new signal) If replacing the probe, use the set point and zero flow signal (ZFS) shown on the new calibration certificate that came with the probe. If replacing the processor board, use the set point and ZFS on the original calibration certificate. If the original calibration certificate is not available, contact MAGNETROL with the serial number of the unit found on the nameplate. New signal is the value measured under step 2. NOTE: If the TA2 is calibrated for a gas other than air, there are two ZFS values on the certificate. One is for air and the other is for the particular gas. Use the ZFS for air when making the adjustment in air. 4. Enter this new set point into the TA2 instead of the value on the calibration certificate under Factory Config ’ Cal Parameters A ’ Set Point. 62 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 5. Return to the signal screen, similar to step 2, ensuring there is no flow over the sensor. The signal value should now agree with the original ZFS within 1%. If desired, steps 2 through 5 can be repeated. 6.4 Flow Recalibration Calibration of the TA2 requires a flow bench or other method for determining the flow rate. Using this procedure, the user can re-calibrate the unit himself or use a local flow calibration facility rather than returning the unit to the factory for recalibration. With an insertion probe, it is not necessary to calibrate in the same size pipe as the unit is installed in. The TA2 has internal scale-up factors which adjusts the data from the calibration pipe size to the installation pipe size. Calibration requires the TA2 sensor to be positioned in a test section; the test section should have a sufficient upstream and downstream straight run to ensure the formation of a fully developed flow profile. Calibration should be performed using the same gas which the unit is calibrated for. Optionally, an air equivalency calibration can be performed. In this case, calibrate in air and contact the factory for air equivalency factors and equivalent air calibration rate. Recalibration Procedure: 1. Select the set point; this is the temperature in degrees Celsius which the TA2 maintains between the two sensors. If the unit is re-calibrated for the same application, then it is probably not necessary to change the original value. If it becomes necessary to change the set point due to change in the calibration velocity or the type of gas: a. Record the set point under Factory Configuration/ Cal Parameters (A or B)/Set Point. b. Determine the maximum velocity in SFPM which the unit will operate (SFPM equals the SCFM divided by the flow area of the test section in square feet). c. Install the probe in the test section and flow gas that is equivalent to the maximum velocity in the calibration range. d. Using the display, obtain the signal value in mW from the Diagnostics menu. e. Calculate a new set point using the formula: New set point = old set point * (800/measured signal (mW)). 800 mW is the desired maximum power rating for the TA2. f. Enter new /set point in TA2 under Factory Configuration/Cal Parameters (A or B) Set Point. 2. Convert the flow rate in the application to the flow rate in the test section using the formula: Flow in test section = application flow * (flow area of test section/flow area of application) 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 63 a. Allow a flow of a known amount of gas through the test section, recording flow rate and TA2 signal (mW). A minimum of 10 and a maximum of 30 data points including a zero flow value should be obtained. One data point should be taken at a flow rate approximately 20 % greater than the expected operating range. The higher the number of data points, the better the overall accuracy of the instrument. b. Convert the flow rate in the test section to mass velocity in SFPM (Standard Feet Per Minute). This is equivalent to the flow rate in SCFM divided by the flow area in square feet. Convert from other units of measurement as necessary. Use MAGNETROL STP conditions of 20 °C (70 °F) and 1 Atmosphere (14.69 psia). c. Enter the Power and the corresponding Mass Velocity into the TA2 using the display and keypad or using the Fieldbus interface. These values should be entered in increasing order to ensure a monotonically increasing curve. Note password of 126 is required for entry of calibration data. (Contact MAGNETROL if issues using this password.) d. After completion of entry of the calibration data, check the display for the number of points accepted (or table length). If this number is less than the actual number of data points entered, then there is an error in the entry of the calibration data. Ensure that the data is entered so the curve is monotonically increasing. The values of mass velocity and power should always be increasing over the calibration range. e. A Fault message will occur if there are fewer than 10 calibration data points in the calibration table. 3. Enter the flow area of the calibration test section. Units of measurement are the same as selected under Basic Config menu. This value is used in calculating the scale-up factor between the calibration test section and the installation. 7.0 Reference Information 7.1 Description The THERMATEL Model TA2 Thermal Mass Flow Meter provides a mass flow measurement of air and other gases. The TA2 consists of a probe or flow body with electronics either integrally mounted on the probe or remotely located. 64 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ The optional plug-in display module with four-button keypad permits the user to easily make changes in the configuration of the TA2 for application-specific conditions. The display provides an indication of the mass flow, temperature and totalized flow, plus other selectable information. Each instrument is calibrated and configured by MAGNETROL for the type of gas, pipe size, flow area and flow rate. Calibration is performed in a NIST traceable flow bench. The TA2 provides real-time temperature compensation which adjusts the flow measurement due to changing gas properties caused by process temperature changes. 7.2 Theory of Operation The flow element of the TA2 Thermal Mass Flow Meter utilizes a heater and two resistance temperature detectors (RTDs). The heater and the active RTD are contained in one sensor. The second sensor contains the reference RTD and a mass balancing element. The reference RTD measures the temperature of the process where the flow element is installed. A variable power is provided to the heater. The active RTD measures the temperature of the heated sensor in a feedback loop to the electronics. The electronics vary the power to the heater to maintain a constant temperature difference between the active and reference RTDs. As the mass flow rate increases there is a cooling effect on the heated sensor. The power to the heated sensor is controlled to maintain a constant temperature difference between the two sensors. The amount of power required to maintain this temperature difference provides a measurement of the mass flow. There is an inherent non-linear relationship between heater power and the mass flow rate. The microprocessor based electronics convert the heater power to provide a linear measurement of the mass flow rate. The electronics also provide real time temperature compensation which automatically adjusts the flow measurement for changes in process temperature over the entire operating range of the instrument. The temperature measured by the reference RTD and the totalized flow can be viewed on the display, and is also available from the Fieldbus interface. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 65 7.3 Display Module The Enhanced model TA2 has a back-lit, plug-in, rotatable display module. The display module consists of a 2-line ¥ 16-character Liquid Crystal Display with four-push-button keypad for configuring the instrument, or for diagnostics. The display can be rotated in 90-degree increments to permit viewing from various orientations. To rotate the display, remove the two screws on the front of the display module, rotate to the desired position, and reattach. 66 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 7.4 Replacement Parts NOTE: Replacement of the processor board / electronic module or the sensor requires entry of configuration data from the Calibration Certificate.

This portable module plugs into the electronics in the same manner as the normal display and uses the same software menu. This module permits the user to reduce installation cost by having one display module with keypad for multiple TA2 units. Usage of the display module requires that the housing cover be removed during use and thus may not be useable in hazardous areas. In these cases, the HART® option should be utilised. 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ 73 7.7 Dimensions in mm (inches) Integral Mount TA2 114 (4.49) A 3/4" NPT or M20 connection (2 entries - one plugged) 99 (3.89) 132 (5.18) 170 (6.69) Optional compression fitting Typical height when compression fitting is used with half coupling or threadolet 3/4" or 1" NPT recommended /4" NPT: 66 (2.6) 1" NPT: 79 (3.1) 3 Pipe centerline Dimension A: 85 (3.33) without display 99 (3.88) with display Insertion length 25 mm (1) Remote Mount TA2 102 (4.00) 114 (4.49) 3/4" NPT or M20 (2 entries - one plugged) 94 (3.72) 165 (6.50) 2 holes Ø 9,5 (0.37) 70 (2.75) 76 (3.00) 51 (2.00) 95 (3.75) 89 (3.50) insertion length ø 19,1 (0,75) TMR for mounting with compression fitting 74 Insertion length 3/4" NPT or M20 transducer cable connector insertion length BSP Ø 19,1 (0.75) insertion length insertion length NPT ø 19,1 (0,75) TMR with threaded connection ø 19,1 (0,75) TMR with flanged connection 54-650 Thermatel® Model TA2 Transmitter - FOUNDATION fieldbus™ A A B B L1 Flow conditioning plate L L1 L Flanged flow body Threaded flow body Length (L) Code ➀ Size With Flow Conditioning mm (inches) Without Flow Conditioning mm (inches) ➀ 0 1 /2" 203 (8) 1 3 /4" 286 (11.25) 2 1" 381 (15) L1 ➀ ➀ With Flow Conditioning mm (inches) Without Flow Conditioning mm (inches) ➀ Overall Height (B) Height to Centerline (A) NPT-M Flange mm (inches) mm (inches) mm (inches) — 127 (5) — 203 (8.0) 214 (8.4) 248 (9.7) — 191 (7.5) — 203 (8.0) 217 (8.5) 251 (9.9) — 254 (10) ➀ — 203 (8.0) 220 (8.7) 257 (10.1) ➀ 3 1 1 /2" 495 (19.5) 191 (7.5) 305 (12) 95 (3.75) 211 (8.3) 235 (9.3) 274 (10.8) 4 2" 660 (26) 191 (7.5) 406 (16) 95 (3.75) 241 (9.5) 272 (10.7) 318 (12.5) 5 3" 991 (39) 254 (10) 610 (24) 127 (5) 241 (9.5) N/A 337 (13.3) 6 4" 1321 (52) 305 (12) 914 (36) 152 (6) 241 (9.5) N/A 356 (14.0) The upstream length in pipe sizes < 1 1/2" dia. is sufficient to create the flow conditioning effect without need for a flow conditioning plate.

See figure A. As gas flows in a pipe or duct, the flow profile will change with obstructions and changes in flow direction. As the gas flows around an elbow, the momentum causes the gas velocity on the outside of the elbow to increase and the velocity on the inside to decrease. See figure B. RD = 3,000,000 RD = 4,000 Figure A Figure B Turbulent flow profile Flow profile following single elbow Figure C indicates the minimum recommended straight run distances required to obtain the desired fully developed flow profile. If these straight-run distances are not available, the overall accuracy of the flow measurement will be affected; however, the repeatability of the measurement will be maintained. The user has the ability to enter correction factors to compensate for non-ideal flow profile conditions.

Plates are available in flow body type sensor designs (TFT) from 1.5" to 4" pipes. Plates may be purchased separately for pipe sizes 4" to 12" when using insertion probes (TXR). The plate should be installed 2-5 diameters downstream of the nearest obstruction, change in pipe inside diameter or change in flow direction. For TXR designs, the insertion probe can be installed 8 pipe diameters downstream of the plate with 5 diameters required downstream of the TXR.

They will be rebuilt or replaced promptly. Magnetrol International will repair or replace the control, at no cost to the purchaser, (or owner) other than transportation cost if: a. Returned within the warranty period; and, b. The factory inspection finds the cause of the malfunction to be defective material or workmanship. If the trouble is the result of conditions beyond our control; or, is NOT covered by the warranty, there will be charges for labour and the parts required to rebuild or replace the equipment. In some cases, it may be expedient to ship replacement parts; or, in extreme cases a complete new control, to replace the original equipment before it is returned. If this is desired, notify the factory of both the model and serial numbers of the control to be replaced. In such cases, credit for the materials returned, will be determined on the basis of the applicability of our warranty. No claims for misapplication, labour, direct or consequential damage will be allowed. RETURNED MATERIAL PROCEDURE So that we may efficiently process any materials that are returned, it is essential that a “Return Material Authorisation” (RMA) form will be obtained from the factory. It is mandatory that this form will be attached to each material returned. This form is available through Magnetrol’s local representative or by contacting the factory. Please supply the following information: 1. Purchaser Name 2. Description of Material 3. Serial Number and Ref Number 4. Desired Action 5. Reason for Return 6. Process details Any unit that was used in a process must be properly cleaned in accordance with the proper health and safety standards applicable by the owner, before it is returned to the factory. A material Safety Data Sheet (MSDS) must be attached at the outside of the transport crate or box. All shipments returned to the factory must be by prepaid transportation. Magnetrol will not accept collect shipments. All replacements will be shipped Ex Works.
