Make sure all components have been removed from the packing material. Check all the contents against the packing slip and report any discrepancies to the factory. Before proceeding with the installation, do the following: • Inspect all components for damage. Report any damage to the carrier within 24 hours. • Make sure the nameplate model number on the transmitter agree with the packing slip and purchase order. • Record the model and serial numbers for future reference when ordering parts. 2.2 Electrostatic Discharge (ESD) Handling Procedure The MAGNETROL electronic instruments are manufactured to the highest quality standards. These instruments use electronic components that may be damaged by static electricity present in most work environments. • • • • 58-610 Model R82 Radar Transmitter 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 the 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 recommended. Handle circuit boards only by the edges. Do not touch components or connector pins. Make sure that all electrical connections are completely made and none are partial or floating. Ground all equipment to a good, earth ground. 9 2.3 Before You Begin 2.3.1 Site Preparation Each R82 Radar transmitter is built to match the physical specifications of the required installation. Make sure the antenna connection is correct for the threaded or flanged mounting on the vessel or tank where the transmitter will be placed. See Mounting, Section 2.4. Make sure that the wiring between the power supply and Radar transmitter are complete and correct for the type of installation. When installing the Radar transmitter in a general purpose or hazardous area, all local, state, and federal regulations and guidelines must be observed. See Wiring, Section 2.5. 2.3.2 Equipment and Tools MAXIMUM DISTANCE feet (meters) Dielectric 1.7-3.0 3.0-10.0 10.0-100 Turbulence R82 None 26 (8.0) Light, < 0.5" 21 (6.4) Moderate, < 1.0" 14 (4.3) Heavy, > 1.0" 7 (2.1) None 33 (10.1) Light, < 0.5" 26 (7.9) Moderate, < 1.0" 19 (5.8) Heavy, > 1.0" 12 (3.7) None 40 (12) Light, < 0.5" 32 (9.8) Moderate, < 1.0" 24 (7.3) Heavy, > 1.0" 17 (5.2) • • • • No special tools are needed.

Optional 24 VDC (23 mA) power supply. . . . . . . . Optional 2.3.3 Operational Considerations Radar applications are characterized by three basic conditions; Dielectric, Distance (measuring range) and Disturbances (turbulence, foam, false targets, multiple reflections and rate of change). 2.3.3.1 Maximum Distance Sensor Reference Point Sensor Offset (+) Highest Measureable Value Blocking Distance 20 mA Safe Zone Distance Sensor Offset + Tank Height = Distance from process connection to tank bottom Media Level 4 mA Level Offset Figure 7 10 2.3.3.2 Minimum Distance Tank Height Lowest Measurable Value Figure 7 at left shows the maximum measuring range (Distance) based on fundamental conditions of Dielectric, Distance and Turbulence. Maximum distance is calculated as Tank Height + Sensor Offset. It is measured from the Sensor Reference Point (bottom of NPT thread, top of BSP thread or face of a flange). If the liquid level is allowed onto the antenna, noise and media build-up drastically decrease reliable measurement. Liquid should not be allowed closer than 15" (380 mm), BSP: 16" (405 mm) from the bottom of the antenna mounting threads (or face of hygienic flange). The distance from the end of the antenna varies depending on antenna chosen. See Figure 8. 58-610 Model R82 Radar Transmitter 2-inch (50 mm) Antenna 15" (380 mm), BSP: 16" (405 mm) minimum (measured from bottom of threads or flange face) 8-inch (200 mm) Antenna 13" (330 mm) 7" (178 mm) Figure 8 Minimum distance to end of antenna varies depending on antenna used Maximum Recess (m) is 2 × Nozzle Diameter (d) (Schedule 40 maximum) (example: 2" diameter nozzle) 8-inch (200 mm) Antenna 2-inch (50 mm) Antenna 8" (200 mm) 15" (380 mm), BSP: 16" (405 mm) 2" (50 mm) d m 4" (100 mm) 15" (380 mm), BSP: 16" (405 mm) 9" (225 mm) d 4" (100 mm) 3" (75 mm) Maximum Liquid Level Maximum Liquid Level Figure 9 Using nozzle height to maximize useable tank space 2.3.3.3 Problematic Applications; GWR Alternative • • • • 58-610 Model R82 Radar Transmitter Some application concerns can be problematic for Radar. For these, Guided Wave Radar is recommended: Extremely low dielectric media (εr<2.0) Very weak reflections from the liquid surface, particularly during turbulence, can cause poor performance. Tanks heavily cluttered with false targets (mixers, pumps, ladders, pipes, etc.) During times of very low liquid levels of low dielectric media, the metal tank bottom may be detected deteriorating performance. 11 • Foam can either absorb or reflect the microwave energy depending upon the depth, dielectric, density and wall thickness of the bubbles. Due to typical variations in the amount (depth) of foam, it is impossible to quantify performance. It may be possible to receive most, some or none of the transmitted energy. • Extremely high liquid levels (Overflow) conditions when liquid very near the antenna (above the Blocking Distance) can cause erroneous readings and measurement failure. > 10" (25 cm) 1/2 Radius 2.4 Mounting The R82 Radar transmitter can be mounted to a vessel using a variety of process connections. Generally, either a threaded or flanged connection is used. 2.4.1 Installing the Transmitter • • • • Figure 10 Before installing, make sure: Process temperature, pressure, dielectric, turbulence and distance are within the antenna specifications for the installation. End of antenna is protected from bending or breaking. Insulating material is not placed around any part of the Radar transmitter including the antenna flange. Transmitter is being mounted in the optimal location. See following sections: Location, Beam Angle, Obstructions, Nozzles, Stillwells, and Open Channel Flow for specific information. 2.4.1.1 Location Ideally, the Radar transmitter should be mounted providing an unobstructed signal path to the liquid surface where it should illuminate (with microwave energy) the largest, possible surface area. See Section 2.4.1.2, Beam Angle. Unavoidable obstacles will produce reflections that must be minimized during field configuration. Mount in a location equal to 1⁄2 the radius of tank top. Do not mount in center of vessel nor closer than 10" (25 cm) from the tank wall.

Figure 11 12 58-610 Model R82 Radar Transmitter 2.4.1.3 Obstructions Almost any object that falls within the beam pattern will cause reflections that may be misinterpreted as a false liquid level. Although Model R82 has a powerful Echo Rejection routine, all possible precautions should be taken to minimize false target reflections with proper installation and orientation. See Figure 12. 2.4.1.4 Nozzles Improper installation in a nozzle creates “ringing” which will adversely affect measurement. Two Antenna extension lengths are offered to allow the R82 transmitter to work reliably in a variety of nozzles. The Minimum Blocking Distance of 15" (380 mm) is always measured from the bottom of the threads or face of the flange. The related distance as measured from the end of the antenna varies depending on the antenna extension chosen. See Figure 13. Figure 12 The narrow beam width of the 26 GHz, R82 does allow mounting so that the antenna can be recessed inside the nozzle. Optimally, the recessed dimension should never exceed 2¥ the nozzle diameter (Schedule 40 maximum). See Figure 13. Avoiding Obstructions NOTE: If the antenna is recessed in a nozzle it is mandatory that Echo Rejection is run to eliminate any possibility of false reflections. Maximum Recess (m) is 2 × Nozzle Diameter (d) (Schedule 40 maximum) (example: 2" diameter nozzle) 8-inch (200 mm) Antenna 2-inch (50 mm) Antenna 8" (200 mm) 15" (380 mm), BSP: 16" (405 mm) 2" (50 mm) d m 4" (100 mm) 15" (380 mm), BSP: 16" (405 mm) 9" (225 mm) d 4" (100 mm) 3" (75 mm) Maximum Liquid Level Maximum Liquid Level Figure 13 Using nozzle height to maximize useable tank space 58-610 Model R82 Radar Transmitter 13 2.4.1.5 Stillwells • • • • • • Figure 14 • R82 Mounted in Stillwell (Bridle) • The R82 can be mounted in a stillwell but certain considerations should be given: Metal stillwells only: 2" (50 mm) Sched 40 max. Diameter must be consistent throughout length; no reducers. Stillwell length must cover complete range of measurement (i.e., liquid must be in stillwell). Welds should be smooth. Vents: holes <0.125" diameter, slots <0.125" width. If an isolation valve is used, it must be a full port ball valve with an I.D. equal to the pipe diameter. Bridles/Bypass Installations: The launcher should be rotated 90° from process connections. Configuration must include an entry for Stillwell I.D. See Section 2.6.6.2, Item 34- Stillwell I.D. 2.4.1.6 Open Channel Flow Measurement For optimal accuracy, mount the transmitter a minimum of 30" above the flow element (this is dependent on type and size of the flow element). Consult factory for assistance on this dimension. Model R82 Flow Parshall Flume Figure 15 Open Channel Flow Mounting NOTE: Proper position of the Model R82 should be per the recommendation of the flume or weir manufacturer and meeting minimum height recommendations. Mounting at least 30" above the top of the element will yield best accuracy. 14 Install the Model R82 on the inflow side of the flume throat or weir crest in the location defined by the manufacturer of the primary measuring device. The unit should also be aligned with the longitudinal axis of the flume or weir. Open channel flow is performed by using the R82 to measure the level (Head) in a hydraulic structure. The hydraulic structure is the primary measuring element, of which the two most common types are weirs and flumes. Since the primary element has a defined shape and dimensions, the rate of flow through the flume or over the weir is related to the liquid level (Head) at a specified measurement location. The Model R82 is the secondary measuring device which measures the height (Head) of the liquid in the flume or weir. Open channel flow equations stored in the R82 firmware convert the measured Head into units of flow (volume/time). 58-610 Model R82 Radar Transmitter 2.4.2 Installing the Transmitter Launcher Adjustment in #11 Position (Default) Ground Figure 16 Launcher Adjustment in #11 Position (default) Tangent Line Figure 17 Polarization Pattern 30 degrees: Rotate Launcher Mechanism Clockwise (CW) 3 notches Install the Transmitter with its integral antenna by threading into the vessel. DO NOT OVERTIGHTEN as this may cause damage to the plastic threads. • Do not place insulating material around any part of the radar transmitter including the antenna flange. • Installation for NEMA 6P/IP 68: the R82 can be installed to allow for temporary submergence to 6.5 ft. (2m) for 24 hours: - use TFE paste to seal conduit entries or IP 68 cable glands - Do not overtighten plastic housing cover; O-ring develops water-tight seal without excessive tightening 2.4.2.1 Orientation The R82 transmitter utilizes a linearly polarized, microwave beam that can be rotated to improve its performance. Proper orientation can minimize unwanted reflections, decrease sidewall reflections (multipath) and maximize direct reflections from the liquid surface. The internal launcher mechanism can be turned to optimize performance. The launcher has index marks numbered 1–18 (representing 10–180 degrees). The polarization pattern is parallel to the transmitter display when the adjustment mechanism is in the #11 position (factory default). See Figures 16 and 17. 2.4.2.2 Launcher Orientation—Level Application Ideally, the transmitter should be mounted half the radius from the tank wall. In a typical vertical tank, the Launcher should be adjusted so the polarization pattern is parallel to a line tangent to the nearest tank wall. See Figure 17. Rotate the internal Launcher adjustment to achieve the correct Polarization position. Remember each notch on the adjustment wheel is 10 degrees of rotation. See Figure 18. ∠30° 90 degrees: Rotate Launcher Mechanism CW 9 notches ∠90° For horizontal cylindrical vessels, aim beam down the long axis of the vessel. Do not optimize the Echo Strength at one level in the vessel. A transmitter mounted within 10" (25 cm) of a tank wall may demand orientation adjustments to limit multipath and optimize performance. See Section 2.4.2.4, Poor Echo Strength. Tangent Line Figure 18 Examples of Launcher Orientation Adjustments 58-610 Model R82 Radar Transmitter 15 2.4.2.3 Launcher Orientation — Flow Application Orient the R82 transmitter so the Polarization pattern is aimed directly down the throat of the flume or weir. If conduit connections are oriented 90° to the flow, set the Launcher Adjustment to #2. 2.4.2.4 Poor Echo Strength Ground Launcher Adjustment Poor Echo Strength has many potential causes. Following are two initial areas for investigation. Launcher Orientation: Initial launcher orientation is always parallel to tangent of the tank circumference (see Sections 2.4.2.1 & 2.4.2.2). In tall vessels and when antenna is mounted close to the tank wall, improvement in Echo Strength may be attained by rotating the launcher to 90 degrees. )+( )-( Figure 19 Internal Launcher Adjustment Signal Loss: If the Level signal is lost repeatedly at a specific point in the vessel, it is usually a symptom that multipath (side-wall reflections) are causing cancellation by returning to the transmitter exactly 180° out of phase with the Level signal. Utilize the following procedure: • Go to transmitter screen #5 which shows both Level and Echo Strength. • Bring the Level up (or down) to the exact point where the signal is repeatedly lost. Monitor the Echo Strength this point is being approached. The Echo Strength will degrade to a low point before it begins to increase. • At the poorest Echo Strength slowly rotate the launcher 1–2 notches. Allow the unit to stabilize for approximately one minute. Repeat this process until the Echo Strength is optimized. Figure 20 Mounting Over Flume 16 58-610 Model R82 Radar Transmitter 2.5 Ground )+( )-( Wiring Wiring between the power supply and the Radar transmitter should be made using 18–22 AWG shielded twisted pair instrument cable. Within the transmitter enclosure, connections are made to the terminal strip and the ground connections. Trim excess wiring to minimize clutter, noise issues and allow access to Launcher adjustment. See Figure 21. The directions for wiring the Radar transmitter depend on the application: • General Purpose or Non-incendive (Cl I, Div. 2) • Intrinsically Safe 2.5.1 General Purpose or Non-incendive (Cl I, Div. 2) Figure 21 Wiring the Transmitter Caution: The R82 Radar transmitter operates at voltages of 16–36 VDC (GP) and 16-28.6 VDC (IS). Higher voltage will damage the transmitter. NOTES: • If sufficient supply voltage is suspect, use the R82 Low Voltage check (Section 2.6.6.1, #33: Test 4-20 Loop). • For ATEX installation guidelines refer to bulletin BE 58-610. A general purpose installation does not have flammable media present. Areas rated non-incendive (Cl I, Div. 2) have flammable media present only under abnormal conditions.

Before configuring the transmitter, collect the operating parameters information. Then, power-up the transmitter on the bench and follow through the step-by-step procedures for the menu-driven transmitter display. Information on configuring the transmitter using a HART communicator is given in Configuration Using HART (Section 2.7). 2.6.1 Operating Parameters Some key information is needed to configure the Radar transmitter. If necessary, complete the configuration information table in Section 1.1.2. 2.6.2 Setting Up for Shop Configuration The Radar transmitter can be configured at a test bench by connecting a 24 VDC power supply directly to the transmitter terminals. The connections are illustrated in the accompanying diagrams. An optional digital multimeter is shown if current measurements are desired. When using a HART communicator for configuration, a minimum 250 Ω line load resistance is required. See the HART communicator manual for more information. Ground )+( )-( Figure 22 Display and Keypad 18 Launcher Adjustment 2.6.3 Transmitter Display and Keypad The R82 transmitter has a local user interface consisting of a 2-line ¥ 16-character liquid-crystal display (LCD) and 4-push-button keypad. All transmitter measurement data and configuration information is shown in the LCD. The transmitter default display is the measurement screen. It cycles every 2 seconds to display *STATUS*, *LEVEL*, *ECHO STRENGTH*, *%OUTPUT*, *LOOP CURRENT* and *LOCAL TAG* information. The transmitter defaults to this display after 5 minutes if no keystrokes are sensed. You can also access each of these screens individually. The display will not return to the default screen if left in one of these screens. For example, the device can be left to display only LEVEL indefinitely if left in this screen. 58-610 Model R82 Radar Transmitter 2.6.4 Menu Traversal and Data Entry The four push buttons offer various forms of functionality for navigation and data entry (i.e., Navigation, Data Selection, etc.). 2.6.4.1 Navigating Menu Push button Up Keystroke Action Moves to the previous item in the menu branch Down Moves to the next item in the menu branch Back Moves back one level to the previous higher branch item Enter Enters into the lower level branch or switches to the entry mode 2.6.4.2 Data Selection Use this method for selecting configuration data from a specific list. An arrow will appear when in the Data Selection mode. See Figure 23. Use the following procedure: • UP an DOWN arrows to navigate the main menu • ENTER arrow to allow modification of selection • UP an DOWN arrows to choose new selection • ENTER arrow to confirm selection Figure 23 • Use BACK (Escape) key at any time to abort the procedure and escape to previous branch item. 2.6.4.3 Entering Numeric Data Using Digit Entry Use this method to input numeric data, e.g., Sensor Offset. Push button Keystroke Action Moves up to the next highest digit (0,1,2,3,....,9). If held down the digits scroll until the push button is released. Moves down to the next lowest digit Down (9,8,7,6,….,0). If held down the digits scroll until the push button is released. Moves the cursor to the left and deletes a digit. If the cursor is already at the leftmost position, Back then the screen is exited without changing the previously saved value. Moves the cursor to the right. If the cursor is Enter located at a blank character position, the new value is saved. Up Figure 24 NOTES: All numeric values are left-justified, and new values are entered from left to right. A decimal point can be entered after the first digit is entered, such that .9 is entered as 0.9. Some configuration items can have a negative value. In this case, the leftmost position is reversed for the sign (either “-” for a negative value, or “+” for a positive value). 58-610 Model R82 Radar Transmitter 19 2.6.4.4 Entering Numeric Data Using Increment/Decrement Use this method to input the following data: Damping, Echo Loss Delay, Trim Level, Trim 4 mA, Trim 20 mA, Test 4-20 Loop and HART Poll Addr. Push button Up Figure 25 Keystroke Action Increments the displayed value. If held down the digits scroll until the push button is released. Depending on which screen is being revised, the increment amount may increase by a factor of 10 after the value has been incremented 10 times. Decrements the displayed value. If held down the digits scroll until the push button is released. Down Depending on which screen is being revised, the decrement amount may increase by a factor of 10 after the value has been decremented 10 times. Returns to the previous menu without changing Back the original value, which is immediately redisplayed. Accepts the displayed value and returns to the Enter previous menu. 2.6.4.5 Entering Character Data This method is used for entering alphanumeric characters, e.g., Input Local Tag. Push button Keystroke Action Moves to the previous character (Z,Y,X,W). If held down the characters scroll until the push button is released. Moves to the next item character (A,B,C,D). If Down held down the characters scroll until the push button is released. Moves the cursor back to the left. If the cursor is already at the leftmost position, then the Back screen is exited without changing the original tag characters. Moves the cursor forward to the right. If the Enter cursor is at the rightmost position, then the new tag is saved. Up Figure 26 20 58-610 Model R82 Radar Transmitter 2.6.5 Password Protection (Default = 0) The Radar transmitter is password protected to restrict access to certain portions of the menu structure that affect the operation of the system. The password can be changed to any numerical value up to 255. The password is required whenever configuration values are changed. The default password installed in the transmitter at the factory is 0 (password disabled). The last step in the configuration menu provides the option to enter a new password. If 0 is entered as a password, the transmitter is no longer password protected and any value in the menu can be altered (except diagnostic values) without entering a confirming password. NOTE: If the password is not known, the menu item New Password (Section 2.6.6.1 Level Measurement Only, item #35; Section 2.6.6.2 Volume and Level, item #39; Section 2.6.6.3 Flow and Level, item #41) displays an encrypted value representing the present password. Call the factory with this encrypted value to determine the actual password. 2.6.6 Menu: Step-By-Step Procedure The following tables provide a complete explanation of the software menus displayed by the Radar transmitter. Use these tables as a step-by-step guide to configure the transmitter. Sensor Reference Point The first column presents the menus shown on the transmitter display. The displays are in the order they would appear if the arrow keys were used to scroll through the menu. The numbers are not shown on the display. They are provided as a reference only.

Note: Press UP arrow 5 times to reach screen where menu language can be chosen. Display 15 16 Blocking Distance (xxx.x) Level Offset (xxx.x units) Action Comment Enter the Blocking Distance Blocking Distance defines an area near the antenna where reflections can not be measured effectively due to antenna ringing. It is measured from the Sensor Reference point. Default of 15" (380 mm) minimum distance from the process connection to the maximum level. Extend this value when necessary to block reflections from objects close to the antenna. Output will be held at value corresponding to Blocking Distance. Do not allow liquid into the Blocking Distance as false readings can result. Enter the Level Offset Level Offset defines an area at the bottom of the vessel where reflections can not be measured effectively due to angled bottoms, heating coils, reflections from flat metal tank bottoms in low dielectric applications, etc. It is the distance from the bottom of the tank to the lowest valid level reading. Level reading will never be lower than Level Offset value. Model R82 Blocking Distance 15" (380 mm) min.

Flow Units A selection of Gallons/Minute (factory default Flow Unit), Gallons/Hour, Mil Gallons/Day, Liters/Second, Liters/Minute, Liters/Hour, Cubic Meter/Hour, Cubic Ft/Second, Cubic Ft/Minute, and Cubic Ft/Hour are provided. Should some other units of flow be desired, the Custom Unit feature can be used in the Advanced Configuration Menu. 33 2.6.6.3 Radar Transmitter User Menu—Flow and Level (cont.) Note: Press UP arrow 5 times to reach screen where menu language can be chosen. Display Flow Setup 17 (continued from previous page) Action Comment Flow Element Select one of the following primary Flow Elements that are stored in the firmware: Parshall flume sizes of 6", 9", 12", 18", 24", 36", 48", 60", 72", 96", 120" and 144". Palmer-Bwls (PalmerBowlus) flume sizes of 4", 6", 8", 10", 12", 15", 18", 21", 24", 27" and 30". V-notch weir sizes of 22.5°, 30°, 45°, 60°, 90° and 120°. Rect with Ends (Rectangular Weir with End Contractions), Rect w/o Ends (Rectangular Weir without End Contractions), and Cipoletti weir. Crest Length The Crest Length screen only appears when the chosen Flow Element is Cipoletti or one of the Rectangular weirs. Input this length in the user-selected level units. Reference Dist The Reference Distance is measured from the bottom of the antenna threads to the point of zero flow in the weir or flume. This must be measured very accurately in the user-selected level units. For some Flow Elements, such as Parshall flumes, the Reference Dist is the same as the Range value. Weirs and some other Flow Elements will have a Reference Distance that is shorter than the Range value. Maximum Head Maximum Head is the highest liquid level (Head) value in the flume or weir before the flow equation is no longer valid. The Maximum Head is expressed in the user selected Level Units. The R82 will default to the largest Maximum Head value that is allowed for any given flume or weir. The Maximum Head value can be revised depending on the value of the Reference Distance, or for end user preference. Maximum Flow Maximum Flow is a read-only value that represents the flow value corresponding to the Maximum Head value for the flume or weir. Low Flow Cutoff The Low Flow Cutoff (in user-selected level units) will force the calculated flow value to zero whenever the Head is below this point. This parameter will have a default and minimum value of zero. (continued on next page) Totalizers: Units Totalizers: Total NR Mult 34 The Totalizer Units screen is for selection of the units for both the resettable and non-resettable totalizers. Select Gallons (factory default unit), Mil Gallons, Liters, Mil Liters, Cubic Meters, or Cubic Feet. The Total NR Mult screen allows selection of the multiplier to be used for the non-resettable totalizer. The function of the totalizer multiplier is such that if the chosen units are gallons and the multiplier is 100, the totalizer value will increment one whole unit for each 100 gallons. Select 1, 10, 100, 1,000 (default), 10,000 or 100,000. Totalizers: Totalizer NR This is a read only screen that displays the present value of the non-resettable totalizer. Totalizers: Total NR Time This is a read only screen that displays the time that has elapsed since the non-resettable totalizer has been totalizing flow. 58-610 Model R82 Radar Transmitter 2.6.6.3 Radar Transmitter User Menu—Flow and Level (cont.)

Display Action Comment Totalizers: Total R Mode 17 Totalizers: Total R Mult The Total R Mult screen allows selection of the multiplier to be used for the resettable totalizer. The function of the totalizer multiplier is such that if the chosen units are gallons and the multiplier is 100, the totalizer value will increment one whole unit for each 100 gallons. Select 1, 10, 100, 1,000 (default), 10,000 or 100,000. Totalizers: Totalizer R This is a read-only screen that displays the present value of the resettable totalizer. Totalizers: Totalizer R Time This is a read-only screen that displays the time that has elapsed since the resettable totalizer has been totalizing flow. Flow Setup (continued from previous page) Totalizers: Totalizer R Enter Flow Information Using Generic Equation 18 Flow Generic Equation Total R Mode allows the user to enable and disable the resettable totalizer. The default mode is disabled. The Totalizer R Reset screen allows the user to reset the total flow and elapsed time of Totalizer R to zero (Totalizer NR is non-resettable). Since this action will permanently lose this data, a second chance is provided with an “Are you sure?” screen. Generic Eqn Factors Generic Equation is a discharge flow equation in the form of Q = K(L-CH)Hn, where Q = flow (Cu Ft/Second), H = Head (Feet), K = a constant, and L, C and n are user input factors that depend on which Flow Element is being used. Make sure the flow equation is in the form of Q = K(L-CH)Hn, and proceed to enter the values of K,L,C,H and n. Generic Equation Example (using equation for an 8' rectangular weir w/ end contractions) Q = Cubic Ft/Second flow rate L = 8' (weir crest length in feet) H = Head value K = 3.33 for Cubic Ft/Second units C = 0.2 (constant) n = 1.5 as an exponent Q = K(L-CH)Hn Using the factors above, the equation becomes: Q = 3.33 (8-0.2H) H1.5 The discharge flow value for a Head value of 3 feet becomes 128.04 Cubic Ft/Second. If GPM was selected for the Flow Units, the R82 Measured Values screen would display this value converted to 57,490 GPM. 58-610 Model R82 Radar Transmitter 35 Display Action Comment The following table provides an explanation of each of the System Configuration parameters for open channel flow applications using the Custom Table.

When connected to the control loop, the same system measurement readings shown on the transmitter are shown on the communicator. In addition, the communicator can be used to configure the transmitter. To confirm HART hand-held communications, attach unit per Section 2.7.1. If communicator reads GENERIC on first two lines, the HART hand-held does not contain the current DDs (device description) for the Model R82 Radar transmitter. Contact your local HART Service Center and specify a MAGNETROL Model R82 device descriptor. Junction R L > 250 Ω - + See HART Revision Table, Section 2.7.3. 2.7.1 Connections Control Room Display Power Supply Current Meter Figure 28 HART Configuration A HART communicator can be operated from a remote location by connecting it to a remote junction or by connecting it directly to the terminal block in the electronics housing of the Model R82 transmitter. HART uses the Bell 202 frequency shift key technique of high-frequency digital signals. It operates on the 4–20 mA loop and requires 250 Ω load resistance. A typical connection between a communicator and the Model R82 transmitter is illustrated. 2.7.2 Display Menu A typical communicator display is an 8-line by 21-character LCD. When connected, the top line of each menu displays the model (Model R82) and its tag number or address. Usually the bottom line of each menu is reserved for software-defined function keys (F1–F4).

The electronics are mounted in a metal or plastic housing with an innovative, internal launcher orientation mechanism. 3.2 Theory of Operation 3.2.1 Pulse Burst Radar Pulse Pulse Burst The Model R82 is a top-mounted, downward-looking pulse burst radar operating at 26 GHz. Unlike true pulse devices that transmit a single, sharp (fast rise-time) waveform of wide-band energy, the R82 emits short bursts of 26 GHz energy and measures the transit time of the signal reflected off the liquid surface. Distance is calculated utilizing the equation Distance = C ¥ Transit time/2, then developing the Level value by factoring in Tank Height and Sensor Offset information. The exact reference point for distance and level calculations is the Sensor Reference Point—bottom of an NPT thread, top of a BSP thread or face of a flange. 1 ns 500 ns NPT Process Connection Distance = c × (time ÷ 2) BSP Process Connection Hygienic Figure 30 Sensor Reference Point Figure 29 46 58-610 Model R82 Radar Transmitter The exact level measurement is extracted from false echo reflections and other background noise via the use of sophisticated signal processing. The new R82 circuitry is extremely energy efficient so no duty cycling is necessary to accomplish effective measurement. For this reason, the R82 can track high rates of change that were heretofore impossible with existing loop-powered radar transmitters. Sensor Reference Point Sensor Offset (+) Highest Measureable Value Blocking Distance 20 mA Safe Zone Distance Sensor Offset + Tank Height = Distance from process connection to tank bottom Tank Height Media Level 4 mA Lowest Measurable Value Level Offset Figure 31 3.2.2 Equivalent Time Sampling ETS, or Equivalent Time Sampling, is used to measure the high speed, low power EM (electromagnetic) energy. ETS is a critical key in the application of Radar to vessel level measurement technology. The high speed electromagnetic energy (1 ft/nS) is difficult to measure over short distances and at the resolution required in the process industry. ETS captures the EM signals in real time (nanoseconds) and reconstructs them in equivalent time (milliseconds), which is much easier to measure with today’s technology. ETS is accomplished by scanning the tank to collect thousands of samples. The round-trip event on a 40-foot (12.3m) tank takes only 82 nanoseconds in real time. After it is reconstructed in equivalent time it measures 135 milliseconds. 58-610 Model R82 Radar Transmitter 47 3.3 Troubleshooting The Model R82 transmitter is designed and engineered for trouble-free operation over a wide range of operating conditions. Common transmitter problems are discussed in terms of their symptoms and recommended corrective actions. WARNING! Explosion hazard. Do not remove covers unless power has been switched off or the area is known to be nonhazardous. Use of the included PACTware™ PC program is highly recommended and invaluable for troubleshooting and advanced calibration. A HART RS232 or USB modem (purchased separately) is required. See MAGNETROL PACTware™ bulletin 59-101. 3.3.1 Troubleshooting System Problems Symptom Problem Solution Level reading drops out at a Multipath is cancelling good Orient launcher to reduce multipath; turn launcher 10–20 degrees (1–2 index repeatable position in the level signal marks) at a time until multipath at this point disappears. Refer to Section 2.4.2.3 vessel Level reading locked onto a value that is not correct Measurement engine finding 1. Is high dielectric (ε>10) foam present? a reflection it believes is 2. Run Echo Rejection routine with Level below this point (or with Empty tank) to level signal eliminate false echoes LEVEL, % Output and LOOP Basic configuration data values are all inaccurate questionable LEVEL readings are repeatable but consistently high (or low) from actual by a fixed amount 1. Check validity of all configuration data 2. Check DISTANCE value of device against manually measured distance Configuration data does not 1. Ensure proper values for Tank Height and Sensor Offset accurately match tank 2. Check vessel for present liquid level. Trim Level can be used to ensure dimensions exact measurement 3. Reconfigure LOOP values if necessary LEVEL reading on Display is HART Poll Address set a correct but LOOP is stuck at value of 1-15 4 mA Set HART Poll Address to 0 LEVEL reading on Display stuck at value related to Blocking Distance Check actual level. If antenna is not flooded, power down, then power up transmitter with the level well below the antenna. 48 Device believes antenna is flooded (level very near or on antenna) 58-610 Model R82 Radar Transmitter 3.3.2 Error Messages The Model R82 Radar transmitter utilizes a 3-section hierarchy for reporting diagnostic conditions: FAULTS, WARNINGS, and INFORMATION. FAULTS and WARNINGS will be shown in the Home screen when the message is active. A chronological listing of messages can be viewed in the HISTORY screen. FAULT: The highest level in the hierarchy of diagnostics annunciating a defect or failure in circuitry or software that precludes reliable measurement. The current (mA) value unit defaults to 3.6, 22, or HOLD and the Home screen will freeze showing the highest priority Fault. A chronological listing of messages can be viewed in the HISTORY screen. WARNING (MESSAGE): The second level in the hierarchy of Diagnostics annunciating conditions that are not fatal but may affect measurement. The highest priority Warning will be placed on the main (rotating) screen when a Warning is detected but will not affect output current. A chronological listing of messages can be viewed in the HISTORY screen. INFORMATION (MESSAGE): The lowest level in the hierarchy of diagnostic conditions providing operational factors that are not critical to measurement. A chronological listing of messages can be viewed in the HISTORY screen. EFFECTS OF EACH DIAGNOSTIC MESSAGE mA Loop Display Message History Screen ¿ Fault 3.6/22/HOLD Yes Yes Warning No Effect Yes Yes Information No Effect No Yes ¿ Also listed in History screen are changes of “state.” For example, “BC Level” which means Boundary Condition Level.
