Model R82 BE58-110 - Magnetrol International

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.
Up to 12 m (40 ft) range

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).

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

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

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)
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.

EXTENSIVE SELECTION
OF PRIMARY FLOW ELEMENTS
With a total of 35 flume and weir curves stored in the electronics, it would be hard to find an open channel flow application that cannot be handled by the R82 transmitter.
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
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.

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 (#9 position, default) should be
rotated 90° from process connections.
• Configuration must include an entry for PIPE I.D.
