MODEL R82 Non contact radar transmitter for level and volume DESCRIPTION The Model R82 is an economical, loop powered radar transmitter bringing radar to everyday applications. Ultrasonic devices, frequently used in daily applications, can now be replaced using radar technology with its superior performance. The electronics are housed in a single compartment cast aluminium or polycarbonate housing. The R82 measures effectively even when atmospheres above the liquid are saturated with vapour. 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.

Blocking Distance 380 mm (15") measured from bottom of thread Model R82 Liquid DN 50 (2" sch 40) maximum only Level Volume 20-point strapping table Worldwide level and flow solutions P R I N C I P L E O F O P E R AT I O N Model R82 Pulse Burst Radar emits short bursts of 26 GHz energy to a liquid surface. An ultra-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 no duty cycling is needed like with likewise radars. This allows to track high rates of level changes up to 4,5 m/minute (180"/min). Distance = C (speed of light) x T (transit time) 2 Initial Pulse Reflected Pulse Air εr = 1 ORIENTATION The R82 transmitter utilises 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. Each index number represents 10 degrees of rotation. Liquid εr ≥ 1,7 Ground Launcher adjustment in #11 position (default) 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. For horizontal cylindrical vessels aim beam down the long axis of the vessel. Internal launcher adjustment Sensor reference point Tangent Line Launcher Orientation OPERATIONAL CONSIDERATIONS Radar applications are characterized by three basic conditions: • Dielectric • Distance (measuring range) • Disturbances (turbulence, foam, false targets, multiple reflections and rate of change) Highest Measureable Value Sensor Offset + Tank Height = Distance from process connection to tank bottom Maximum measuring range (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 flange). The maximum distance chart shows the maximum measuring range of each antenna based on dielectric and turbulence.

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. Q=K(L-CH)Hn Model R82 Flow Parshall flume 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 non-resettable. Several multipliers are selectable to allow for proper scaling. Totalizer time is also recorded to show how long each totalizer has been recording flow. ENCLOSED FLUMES AND WEIRS Conditions: turbulence and changing dielectric. NOTE: For optimal accuracy, mount the transmitter a minimum of 75 cm (30") above the flow element (this is dependent on type and size of the flow element). Consult factory for assistance on this dimension. 3 MOUNTING >25 cm 10” 1/2 radius Distance Meters Beam Spread (W) Feet Meters 3 10 0.74 Feet 2.5 6 20 1.47 4.9 9 30 2.21 7.4 12 40 2.95 9.8 ∝14° W Maximum recess (m) is 2 x nozzle diameter (d) (Sch. 40 maximum) example: 100 mm (4") diameter nozzle example: 50 mm (2") diameter nozzle 200 mm (8") antenna 50 mm (2") antenna 205 mm (8") 50 mm (2") d 100 mm (4") 230 mm (9") m 100 mm (4") d 380 mm (15") Maximum liquid level 205 mm (8") 380 mm (15") 75 mm (3") Maximum liquid level Maximizing useable capacity S TA N D P I P E S , S T I L LW E L L S A N D B R I D L E S The R82 can be mounted in a standpipe or stillwell but certain considerations should be given: • Metal stillwells only: DN 50 (2" sch 40) maximum only. • 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 < 3 mm (0.125") diameter, slots < 3 mm (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 adjustment (#11 position, default) should be rotated 90° from process connections. • Configuration must include an entry for PIPE I.D. 4 205 mm (8") m d Maximum liquid level T R A N S M I T T E R S P E C I F I C AT I O N S FUNCTIONAL/PHYSICAL Description Specification Power (at terminals) Output Span Resolution Weatherproof: 16 to 36 V DC / ATEX Intrinsically Safe: 16 to 28,4 V DC 4-20 mA with HART®, 3,8 mA to 20,5 mA useable (meets NAMUR NE 43) 380 mm (15") to 12 m (40') - depending process conditions and measured from thread Analog: 0,01 mA Display: 0,1 cm (0,1 inch) 400 Ω @ 20 mA - 24 V DC or 350 Ω @ 22 mA - 24 V DC Adjustable 0-45 s Adjustable 3,6 mA, 22 mA, HOLD last output HART® communicator, PACTware® and/or 4-button keypad 2-line x 16-character display English/Spanish/French/German IP 66 / Aluminium A356T6 (< 0.20 % copper) or IP 67 / polycarbonate ATEX II 1 G Ex ia IIC T4 / IEC Ex ia IIC T4 Ga, intrinsically safe Other approvals are available, consult factory for more details Functional safety to SIL 1 as 1oo1 in accordance to IEC 61508 – SFF of 89,1 % Ui = 28,4 V, li = 94 mA, Pi = 0,67 W // Ui = 28 V, li = 120 mA, Pi = 0,84 W Ci = 5,5 nF, Li = 370 µH ANSI/ISA-S71.03 SA1 (Shock), ANSI/ISA-S71.03 VC2 (Vibration) 1,45 kg (3,2 lbs) incl. 50 mm (2") polypropylene antenna 0,73 kg (1,6 lbs) incl. 50 mm (2") polypropylene antenna Max: H 376 mm (14.80") x W 101 mm (3.98") - cast alu housing and tall sensor Min: H 204 mm (8.03") x W 96 mm (3.78") - polycarbonate housing and short sensor Loop Resistance Damping Diagnostic Alarm User Interface Display Menu Language Housing Material Approvals SIL (Safety Integrity Level) Electrical Data Equivalent Data Shock/Vibration Class Net Weight Cast aluminium Polycarbonate Overall Dimensions PERFORMANCE Description Specification Linearity Measured error ± 5 mm (0,2") or 0,05 % of tank height, whichever is greater ± 5 mm (0,2") or 0,05 % of tank height, whichever is greater.
