APPLICATION The POLARIS MA1 electromagnetic flow meter has been designed to measure volume flow rates of electrically conductive liquids in closed piping systems. Measurements can be done in both flow directions, with high measurement accuracy over a wide range of flow rates. The minimum required conductivity of the measured medium is 5 µS/cm. The microprocessor controlled MA1 transmitter processes measurement data and displays and transmits various types of measurement results. The MA1 supports the option of ® HART communication protocol for use with PACTware. Although basic configuration settings such as transmitter calibration are defined at the factory, other settings such as those for measurement data processing, analysis, display and output are user definable. User settings are protected by a user definable password. Settings that are essential for proper operation of the transmitter in conjunction with the sensor (e.g. calibration and initialization values) are accessible only to service technicians via a password that is not provided to customers. 2. MEASUREMENT PRINCIPLE The function of an electromagnetic flow meter is based on Faraday’s electromagnetic law. The meter sensor consists of a non-magnetic and non-conductive tube with two embedded measuring electrodes to pick up the induced voltage. To create an alternating magnetic field, two coils are fitted onto the tube in parallel with the plane defined by the active parts of the measuring electrodes. Now if a conductive liquid flows across magnetic field B, voltage U will appear on the measuring electrodes proportional to the flow velocity v and the conductor length l. U=Bxlxv U B l v induced voltage magnetic flux density distance between the measuring electrodes liquid flow velocity Figure 1. Measurement principle As the magnetic flux density and distance between the electrodes are constant, the induced voltage is proportional to the liquid flow velocity in the tube. The value of the volume flow rate can then be readily determined as a product of the flow velocity and square section of the tube, Q = v x A. 6 62-600 POLARIS Electromagnetic Flow Meter 3. TECHNICAL DESCRIPTION The electromagnetic flow meter consists of a sensor through which the measured liquid flows and an electronic unit where the low-level signal from the sensor is modified to a standardised form suitable for further processing in various industrial electronic devices. The output signal is proportional to the volume flow rate of the measured liquid. The only factor limiting the application of electromagnetic flow meters is the requirement that the measured liquid shall be conductive and non-magnetic. The electromagnetic flow meter can be designed either as an integral device or with the sensor separated from the associated electronic unit. In the former case, the electronic unit is fitted directly onto the meter sensor, in the latter case it is connected to the sensor by a special cable. The sensor design shall take into consideration the type of the measured liquid and its operational parameters. To facilitate fitting into the liquid piping, the sensor can be provided with end flanges or as a wafer style design. The supply voltage, types of output signal and communication interface can be selected according to the customer requirements. 4. SENSOR TECHNICAL PARAMETERS The sensor environment must be free of any strong magnetic fields. 4.1. Selection of correct sensor size The following table shows minimum and maximum flow rates for various sensor sizes and flow velocities ranging from 0.33-33 ft/s (0.1-10 m/s). The best operational properties will be achieved at the flow velocity range of 1.64-16.4 ft/s (0.5 to 5 m/s). The measurement accuracy is degraded at lower velocities while at higher velocities the turbulences and contact edges may cause undesirable interference. Minimum and maximum flow rates for various sensor sizes Qmin corresponds to flow velocity 0.33 ft/s (0.1 m/s) Qmax corresponds to flow velocity 33 ft/s (10.0 m/s) 62-600 POLARIS Electromagnetic Flow Meter 7 Table 1.

Selection of electrode material In most cases, electrodes made of stainless steel, quality grade 1.4571 (17248) are satisfactory. These electrodes come standard for the rubber liners. For more corrosive applications it may be desired to go to Hastelloy C4 electrodes, which are standard with the PTFE and ECTFE liners. On request, tantalum or titanium electrodes can be provided. 4.3. Selection of sensor tube lining The sensor lining material selection depends on the operational parameters of the measured liquid. Technical rubber This lining material is suitable for less corrosive liquids and operational temperatures from +32°F (0°C) to +176°F (+80°C). It is sufficient for most applications in water supply and waste water treatment plants. Technical rubber is available as hard rubber or soft rubber. Soft rubber lining is recommended for liquids containing abrasive particles, such as sand grains. PTFE A universal solution for highly corrosive liquids and temperatures ranging from -4°F (-20°C) to +302°F (+150°C). Typical applications are in the chemical and food processing industries. ECTFE A similar solution as PTFE except used for larger line sizes. Temperature range from -4°F (-20°C) to +266°F (+130°C). 8 62-600 POLARIS Electromagnetic Flow Meter 4.4. Integral or remote meter version The Electronic unit can be installed directly on the sensor (integral version) observing the operating conditions of the sensor or be mounted separately on the outside (remote version). 4.4.1 Remote version The remote meter version is to be used at the measurement spots with ambient temperature exceeding 140°F (60°C) where the reliable function of the electronic unit would not be ensured at all times. In such cases, use the remote meter version and place the separate electronic unit at a location where the ambient temperature never exceeds this rating. For process temperatures higher than 212°F (100°C) it is recommended to use the remote version. Furthermore, the transmitter needs to be mounted separately from the sensor if the mounting area is difficult to access there is a lack of space there is strong vibration Figure 2. Proper installation of cables at high humidity and wetness The Electronic unit has to be mounted free of vibrations! Caution: The electrode cable must be fixed. If the conductivity of the medium is low, cable movements may change the capacity considerably and thus disturb the measuring signal. Do not lay the cables close to electrical machines and switching elements. Equipotential bonding must be ensured between sensor and transmitter. Do not connect or disconnect the field coil cable before the primary power of the meter has been disconnected. To prevent electromagnetic interference via the connecting cable, the sensor and separate electronic unit of the meter in the remote version should be located as close as possible to one another. The maximum cable length depends on the conductivity of the measured liquid (see Fig. 3). 62-600 POLARIS Electromagnetic Flow Meter 9 Remote Cable Length 60 M E 40 T 20 E R 0 S 0 200 150 F E 100 E 50 T 0 10 20 30 40 50 Conductivity (µS/cm) Figure 3.

COMISSIONING 5.1 Installation of electromagnetic flow meters The meter installation work shall be performed in strict observance of the procedures and rules described in this manual. To prevent undesirable interference, the power cables shall be laid at least 10 inches (25 cm) away from all signal cables. The signal cables include the cable connecting the sensor and the associated electronic unit (in the case of a remote meter version) and output signal cables. All cables shall be laid outside the thermal insulation layer on the piping (if any). Only shielded conductors shall be used to connect the output signals. In applications where high levels of electromagnetic field interference at the measuring location can be expected (e.g. in the vicinity of power frequency converters), the remote meter version should be avoided. In these cases it is also recommended to include a filter in the power supply line to the electronic unit. Filter specification: The filter is intended to suppress dissemination of the undesirable high frequency disturbances from the power supply cable to the flow meter system. Use any commercial filter of suitable parameters including protection class, and install it as close to the meter as possible. If need be, the filter can be placed in a special protection housing. When installing the filter, observe the applicable safety regulations. Rated voltage: Rated current: Suppression characteristic: 250V/50Hz 0.5A and more 10kHz: 10 to 20dB 10MHz: 40dB 5.2 Piping No chemical injection or batching unit (such as chlorine compound injector) should be located at the input side of the sensor. The insufficient homogeneity of the flowing liquid may affect the flowrate values indicated by the meter. The meter performance will be the best if the liquid flow in the piping is well stabilized; therefore it is necessary to observe specific rules for the sensor placement in piping. In the contact planes between the sensor and the adjoining piping sections there should be no edges as these would cause flow turbulence. Make sure that 5 diameters of straight piping section is provided before and 3 diameters after the sensor; their required length is proportional to the inner diameter of the piping concerned. If more than one flow-disturbing element such as pipe bend or fitting is located near the sensor, the required length of straight piping section on the sensor side concerned should be multiplied by the quantity of such elements. In the cases of bi-directional flow-rate measurement, the same conditions concerning flow stability shall be met at the input and output sides of the sensor. In the cases where the pipe size larger than that of the meter sensor, it is necessary to use conical reduction pieces with the angle of taper not exceeding 15°. In the cases of bi-directional flow measurement, the minimum length of straight piping sections on both sides is 5 DN. In horizontal sensor installations, to prevent bubbling, use concentrically-fitted reduction pieces (see standard ČSN EN ISO 6817). Pipe narrowing sections with angles not exceeding 8° can be taken for straight sections. In the cases where the liquid is pumped, the flow sensor shall always be placed at the output side of the pump. The required length of the straight piping section between the pump and sensor is at least 25 diameters. The sensor shall be always placed before the closing valve in the piping. 16 62-600 POLARIS Electromagnetic Flow Meter The sensor can be fitted in the piping in either horizontally or vertically. However, make sure that the electrode axis is always horizontal and, if the sensor is mounted in a horizontal position, the flange section for attachment of the MA1 faces upwards. In the cases where the sensor is mounted in a vertical position, the flow direction shall always be upwards. To ensure correct meter function at all times, the measured liquid shall completely fill up the sensor and no air bubbles shall be permitted to accumulate or develop in the sensor tube. Therefore the sensor shall never be placed in the upper pocket of the piping or in a vertical piping section where the flow direction is downwards. In piping systems where complete flooding of the piping cannot always be guaranteed, consider placing the sensor in a bottom pocket where full flooding is ensured. If the sensor is located near a free discharge point, such point shall be by at least 2 diameters higher than the top part of the sensor. Make sure that the adjoining piping is clamped/supported as close to the sensor as possible, to prevent vibrations and damage to the sensor. In applications where continuous liquid flow is essential, a bypass shall be provided to allow for sensor servicing. A sensor bypass may also be a reasonable solution in the cases where, to dismantle the flow sensor from the piping, liquid from a very long piping section would have to be discharged. Figure 6.

Bypass 62-600 POLARIS Electromagnetic Flow Meter 5.3 Earthing Every sensor, with the exception of ½” (DN20), has a third grounding electrode provided at the base of the spool piece. Additional grounding is possible utilizing the blue grounding lugs on the neck of the sensor. A connection should be made to the electrically conductive piping (mating flanges) upstream and downstream of the sensor to the grounding lugs. Grounding rings can also be provided if the sensor is installed in non-conductive piping. When using a remote transmitter, additional grounding is possible by connecting the grounding lug on the sensor to the external grounding on the remote transmitter housing using a copper conductor of cross-section 4mm2. Figure 18. Grounding the remote transmitter 5.3.1 Cathodic protective units With a remote transmitter, ensure the transmitter is isolated from earth ground. Transmitter should be at same potential as sensor. Ground everything to the same ground as the cathodic protection. Warning According to EN 50178:1997 all electrical circuits with protective safety isolation without any protection against contacts must observe the following maximum voltages: Maximum AC voltage (root mean square value) 25 V Maximum DC voltage 60 V Do not connect PE to any higher voltage! 5.4 Remote transmitter with IP68 sensor. The transmitter is supplied with a permanently attached connecting cable in protection class IP67. The other end of the connecting cable is loose. The customer connects the cable to the sensor terminal box itself. Terminal box is equipped with a gland M20x1.5 and terminal board with WAGO terminals. The housing is capped with O - ring. In this case it is the sensor with IP67 protection. 62-600 POLARIS Electromagnetic Flow Meter 19 For a sensor with IP68 protection, the inside of the terminal box must be filled with supplied resin GHB1. Potting compound GHB1 (250 ml) including the necessary accessories are included in delivery for remote version IP68. The application resin procedure GHB1: Remove the protective foil. Mix the two components about 2 min. Place the funnel. Cut off the bag with the resin. Pour the contents of the bag to the brim to the terminal box. Curing time mixture is up to 150 minutes. Temperature during potting is +15°C to +30°C. 6. MA1 TRANSMITTER: MODE OF OPERATION AND CONFIGURATION 6.1 System design The meter consists of a sensor and a MA1 transmitter. The device can be used to perform measurements with any liquid, conductive media, providing that the sensor’s material is suitable for the product being used. The MA1 transmitter generates the inductive current necessary for the magnetic field and preprocesses the induced voltage at the electrodes. 6.1.1 Data memory chip DSM The replaceable data memory chip (DSM) is an EEPROM device in a DIL-8 housing, located in a socket on the power supply board. It contains all characteristic data of the sensor e.g. sensor constant, version or serial number. Consequently, the memory module is linked to the sensor and in case of a transmitter replacement it has to remain by the sensor! After replacing the transmitter or its electronics, the DSM will be installed in the new transmitter. After the measuring system has been started, the measuring point will continue working with the characteristic values stored in the DSM. Thus, the DSM offers maximum safety and high comfort when exchanging device components. 20 62-600 POLARIS Electromagnetic Flow Meter Power supply board MA1 Slot DSM Figure 19. Power supply board MA1 At any exchange watch the polarity of the memory chip. Pin 1 is signed by a dot or a notch. 6.1.2 Safety of operation A comprehensive self-monitoring system ensures maximum safety of operation. Potential errors can be reported immediately via the configurable status output. The corresponding error messages will also be displayed on the transmitter display. A failure of the auxiliary power can also be detected via the status output. When the auxiliary power fails, all data of the measuring system will remain in the DSM (without back-up battery). All outputs are electrically isolated from the auxiliary power, the sensor circuit and from each other. 62-600 POLARIS Electromagnetic Flow Meter 21 7. OUTPUT 7.1 Output signal All signal outputs: Electrically isolated from each other and from ground. Analog output: 0/4-20mA current output, electrically isolated, optional with ® HART for PACTware. ® (Using the HART -protocol the current output has to be assigned to volume flow in the mode of 4-20mA – Contact the factory to download the DTM) Pulse output: Pulse width; default value 50 ms Pulse width adjustable range is 0.5 ... 2000 ms 50% duty cycle When programming the pulse duration, a plausibility check is carried out. If the selected pulse duration is too long for the set upper range value, an error message will be displayed. fmax = 1 kHz passive via optocoupler U = 24 V Umax = 30 V Imax = 60 mA Pmax = 1.8 W Pulse value: 1 pulse/unit The pulse value can be multiplied by a factor between 0.001 - 100.0 (decade increments) of the selected pulse unit (e.g. m³) Status output: for: forward and reverse flow, MIN flow rate, MAX flow rate or alarm, passive via optocoupler U = 24 V Umax = 30 V Imax = 60 mA Pmax = 1.8 W 7.2 Failure signal A failure in the meter can be indicated via the current output or the status output. The current output can be set to a failure signal (alarm) of I < 3.8 mA or I > 22 mA. The status output can be configured as make or break contact. 7.3 Load of the current output Standard version: HART minimum load 22 > 600 Ohm 250 Ohm 62-600 POLARIS Electromagnetic Flow Meter 7.4 Damping Programmable from 0 to 60 seconds. 7.5 Low flow cut-off The low-flow cut-off can be set to values between 0 and 20% using the software. The set value refers to the upper range value. If the measured value is lower than the set volume, the flow rate will set to 0.0. This results in the analog output being set to 0/4 mA, and the pulse output will stop generating pulses. The configurable hysteresis takes effect in only one side while exceeding this limit. 8.

MA1 OPERATING CONDITIONS 9.1 Environmental conditions 9.1.1 Degree of protection MA1 standard housing is IP67. Caution: Ingress protection IP 68 is only achieved if this particular model is selected with remote electronics. Danger: Particular care must be taken if the window in the housing becomes fogged over or discolored because moisture, water or product might seep through the wire sheath into the terminal compartment in the housing. Warning Electromagnetic compatibility is only achieved if the electronics housing is closed. Leaving the enclosure open can lead to electromagnetic disturbances. 9.2 Process conditions 9.2.1 Fluid temperature The data sheet/rating plate of the connected transmitter must be observed. With directly mounted transmitter on the sensor the heat entry must be considered from the process to the transmitter. 9.2.2 State of aggregation Liquid. 9.2.3 Viscosity No restrictions. The data sheet/rating plate of the connected transmitter must be observed. 9.2.4 Fluid temperature limit The data sheet/rating plate of the connected transmitter must be observed. 9.2.5 Flow rate limit The data sheet/rating plate of the connected transmitter must be observed. 9.2.6 Pressure loss The data sheet/rating plate of the connected transmitter must be observed. 24 62-600 POLARIS Electromagnetic Flow Meter 9.2.7 Empty pipe detection Transmitters have an on and off switch for empty pipe detection. The operating reliability depends on the conductivity of the liquid medium and the cleanliness of the electrodes. 10.

Transmitter Caution: Do not connect or disconnect the field coil cable before the primary power of the meter has been disconnected! 26 62-600 POLARIS Electromagnetic Flow Meter If the transmitter is mounted separately from the sensor, the following cables must be used: Electrode cable and field coil cable as shielded twisted pair. In order to protect the cable from external interference, the twisted-pair wires are covered by an additional, overall shield e.g. PAARTRONIC CY-CY-LiYCY (TP) 2x2x0.25mm² (UNITRONIC CYPiDY (TP) 2x2x0.25mm²). At cable length more than 10m a wire cross section of at least 0,5mm² is required e.g. PAARTRONIC CY-CY-LiYCY (TP) 2x2x0.5mm². The outer shield is grounded by means of special EMC-compliant cable glands at both ends of the cable. Connecting the cable shield in the cable gland: 11. MAINTENANCE AND REPAIR The MA1 meter is designed as maintenance-free performance. It contains no parts which have to be replaced or adjusted cyclically. While commissioning or maintenance, mains power must be switched off. Do not connect or disconnect the wirings between sensor and transmitter while power is on. The transmitter electronics may be exchanged only as a complete module. A completely new transmitter may also be purchased. 11.1 Replacing the transmitter The transmitter can be replaced in the field without effecting the calibration of the flow meter when the DSM chip is also replaced. 1) Remove current transmitter by unscrewing the four screws on the sensor neck and exposing the sensor wiring. 2) Unplug the sensor from the current transmitter. 3) Remove the DSM chip (refer to section 6.1) from the power board. To get to the power board, remove the faceplate and display module. 4) Plug the current DSM chip into the new transmitter on the power board. The same procedure can be used as was completed on the removal of the DSM chip. 5) Connect the transmitter wiring to the current sensor, similar to step 2. 6) Screw on the new transmitter to the current sensor. 7) Transmitter is now operational with the same settings as original calibration. 62-600 POLARIS Electromagnetic Flow Meter 27 12. MA1 Menu Structure 12.1 Introduction The MA1 unit can be operated depending on equipment by using the keyboard or via PACTware using HART protocol. In the following, transmitter operation and parameterization using the keyboard are described. The keyboard is located in the electronic compartment and covered by an inspection window. Figure 21. MA1 Transmitter with keyboard 12.2 Display The display has an integrated back lit, alphanumeric display with two 16-character lines. Measurement data and settings can be read directly from this display. The LCD display is designed to be operated at temperatures ranging from -4°F to +140°F (-20 °C to +60°C) without incurring any damage. However, at freezing or near-freezing temperatures, the display becomes slow and readability of the measured values is reduced. At temperatures below +14 °F (-10°C), only static values (parameter settings) can be displayed. At temperatures exceeding 140°F (60°C), contrast decreases substantially on the LCD and the liquid crystals can dry out. 12.3 Operating modes The MA1 can be operated in the following modes: 1. Display mode: In display mode, measured values can be displayed in various combinations and settings can also be displayed. Parameter settings cannot be changed in this mode. Display mode is the standard (default) operating mode when the device is switched on. 2. Programming mode: In programming mode, parameters can be redefined. After entering the correct password, changes that are permissible for the customer (customer password) or all functions (service password for technicians) can be realized. NOTE – If password is manually changed it must be saved! If the customer password is lost the manufacturer cannot retrieve it without returning the unit. 28 62-600 POLARIS Electromagnetic Flow Meter 12.4 Operation 12.4.1 Operation interface Functional classes are displayed as headings beneath which displays and parameters are shown in logical groups. Beneath this is the menu level, which lists all measured value displays or the headings for their underlying parameters (parameter level).
