Model R82 Pulse Burst Radar Level Transmitter D E S C R I P T I O N The Magnetrol® Model R82 is an economical, loop-powered radar transmitter bringing radar to everyday applications. Daily applications that have been considered for ultrasonic can now utilize the superior performance of radar technology. The electronics are housed in a compact, single compartment cast aluminum or Lexan® housing. The R82 measures effectively even when atmospheres above the liquid are saturated with vapor. Pulse Burst technology and advanced signal processing manage common disturbances such as false echoes caused by obstructions, multi-path reflections from tank sidewalls or turbulence caused by agitators, aggressive chemicals, or aerators. T E C H N O L O G Y Model R82 Pulse Burst Radar emits short bursts of 26 GHz energy. High-speed timing circuitry measures the time of the signal reflected off the liquid surface. Sophisticated signal processing filters out false reflections and other background noises. The exact level is then calculated by factoring tank height and sensor offset information. The Model R82 circuitry is extremely energy efficient so duty cycling is not needed as it is with other radar products. This allows tracking of high rates of level change up to 180"/min (4.5m/min). A P P L I C A T I O N S MEDIA: Liquids and slurries; hydrocarbons to water based media (dielectric 1.7–100). VESSELS: Most effective in storage vessels up to rated temperature and pressure. Pits and sumps, metallic and non-metallic tanks, others including plastic, glass-lined and concrete. CONDITIONS: Virtually all level measurement and control applications including process conditions exhibiting varying specific gravity and dielectric, visible vapors, high fill/empty rates and some turbulence. MARKETS: All process markets including replacement of loop-powered, ultrasonic transmitters.

Unusual flow applications can readily be accomplished through the use of either the 20-point Custom Table or the Generic Discharge Flow Equation which allows a direct entry of unique flow equations. Dual Flow Totalizers Two 7-digit flow totalizers are provided for recording flow in cubic feet, gallons, million gallons, liters, million liters, or cubic meters. One totalizer is resettable and the other is nonresettable. Several multipliers are selectable to allow for proper scaling. Totalizer time is also recorded to show how long each totalizer has been recording flow. 2 SUMPS ENCLOSED FLUMES AND WEIRS CONDITIONS – Turbulence and Changing Dielectric NOTE: 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. T E C H N O L O G Y P U L S E B U R S T R A D A R The R82 transmitter is a top-mounted, downward-facing pulse burst radar operating at 26 GHz. Unlike true pulse devices (Eclipse Guided Wave Radar) which transmit a single, sharp (fast rise-time) waveform of wide-band energy (Figure 1), the R82 emits short bursts of 26 GHz energy (Figure 2) and measures the transit time of the signal reflected off the liquid surface. The exact level measurement is extracted from false target reflections and other background noise via the use of sophisticated signal processing. The R82 circuitry is extremely energy efficient so no duty cycling is necessary to accomplish effective, measurement. For this reason it can track high rates of change (180 inches [450 cm] per minute) that have been impossible with existing loop-powered radar transmitters. Distance is calculated utilizing the equation Distance equals the Speed of light multiplied by the transit time divided by two (Distance = C × Transit Time/2), then developing the level value by factoring in tank height and sensor offset information (Figure 3). 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). By inputting the type and geometry of a vessel, the electronics can calculate the liquid volume in the vessel. In a similar operation, the Model R82 can perform open channel flow measurement by converting the level reading into units of volume per time. Common tank shapes, flumes and weirs are stored in the R82 software. A 20-point custom table is also available for unusual tanks or primary flow elements.

Refer to Figure 3 on page 3. It is measured from the sensor reference point (bottom of NPT thread, top of BSP thread, or face of flange). The Maximum Distance chart shows the maximum measuring range of each antenna based on dielectric and turbulence.

Generally either a threaded or flanged connection is used. L O C A T I O N Ideally, the radar transmitter should be mounted 1⁄2 radius from center, providing an unobstructed signal path to the liquid surface where it should illuminate (with microwave energy) the largest possible surface area. Do not install in center of tank top or within 10 inches (25 cm) of tank wall. Tank walls may produce reflections that must be minimized during field configuration (Orientation). Refer to Figure 4. B E A M A N G L E Figure 6 shows the beam angle for the R82 antennas. Ideally, the beam pattern should illuminate the maximum liquid surface with a minimum of striking other objects in the vessel including the tank wall. Use these drawings to determine the optimum installation location. O B S T R U C T I O N S Almost any object that falls within the beam pattern will cause reflections that may be misinterpreted as a false liquid level. Although the R82 has a powerful Echo Rejection routine, all possible precautions should be taken to minimize false target reflections with proper installation and orientation.

Ideally, the antenna should be mounted so the end of the antenna is a minimum of 0.5" (12 mm) below the nozzle (be sure to include any nozzle dimension inside the vessel). Two antenna extension lengths (2" or 8") are offered to allow the R82 transmitter to work reliably in a variety of nozzles. 2-inch (50 mm) Antenna 15" (380 mm), BSP: 16" (405 mm) minimum (measured from bottom of threads or flange face) 13" (330 mm) The Minimum Blocking Distance of 15" (380 mm), BSP: 16" (405 mm) is always measured from the bottom of the threads or face of a flange. The related distance (as measured from the end of the antenna) varies depending on the antenna extension chosen. Refer to Figure 7. When necessary, the narrow beam width of the 26 GHz R82 does allow mounting so that the antenna is recessed inside the nozzle. Optimally, the recessed dimension should never exceed 2× the nozzle diameter (Sch. 40 maximum). Refer to Figure 8. 8-inch (200 mm) Antenna 15" (380 mm), BSP: 16" (405 mm) minimum (measured from bottom of threads or flange face) 7" (178 mm) Figure 7 Minimum Blocking Distance Maximum Recess (m) is 2 × Nozzle Diameter (d) (Sch. 40 maximum) example: 2" diameter nozzle example: 4" diameter nozzle 8-inch (200 mm) Antenna 2-inch (50 mm) Antenna 8" (200 mm) 8" (200 mm) 15" (380 mm), BSP: 16" (405 mm) 2" (50 mm) d 4" (100 mm) 15" (380 mm), BSP: 16" (405 mm) 9" (225 mm) Maximum Liquid Level m d 4" (100 mm) 8" (200 mm) m d 3" (75 mm) Maximum Liquid Level Maximum Liquid Level Figure 8 Maximizing Useable Capacity 5 O R I E N T A T I O N The R82 transmitter utilizes a linearly polarized, microwave beam that can be rotated to improve its performance. Proper orientation can minimize unwanted target reflections, decrease sidewall reflections (multipath) and maximize direct reflections from the liquid surface. The polarization pattern is parallel to the transmitter display when the mechanism is at the #11 position. Refer to Figure 10. Each index number represents 10 degrees of rotation. 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. Refer to Figure 9. For horizontal cylindrical vessels, direct the beam down the long axis of the vessel.

Figure 11 Use in Standpipe/Stillwell • Configuration must include an entry for PIPE I.D. P R O B L E M A T I C G U I D E D W A V E A P P L I C A T I O N S R A D A R A L T E R N A T I V E Some applications can be problematic for Pulse Burst Radar. The following are examples of when 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. 6 • 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). (Continued on next page.) P R O B L E M A T I C G U I D E D W A V E A P P L I C A T I O N S R A D A R A L T E R N A T I V E • 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. A G E N C Y AGENCY United States Canada ATEX/IEC • Extremely high liquid level (Overflow) conditions when liquid is very near the antenna can cause erroneous readings and measurement failure.
