MEASURING PRINCIPLE
Display
Sun Guard
Microwave signals are generated and transmitted via an antenna.
These signals travel through the antenna propagating the signal
Dual Chamber Housing
(Separate Electronics &
Gland terminals)
into the atmosphere. The signals then travel to the target and are
reflected back to the instrument. Time of Flight is measured to
determine distance (level).

BEAM ANGLE
The Beam Angle (ά) is defined as the angle at the point where the energy density of radar waves becomes half the value of the
maximum energy density at centre.

GENERAL ARRANGEMENT
4-20 mA Analogue Output
The system shows a 138
Pulse Radar with 4 - 20 mA
output & requires only a
single pair of wires and an
auxiliary power supply (24
VDC) for its operation. Digital
Process Indicator, Model 176
with built in 24 VDC power
supply eliminates use of a
separate power supply unit.
Up to 4 nos. relay outputs
(optionally) are available in
176 Digital Process Indicator
which can be used further for
operation of digital devices
like motors, pumps, valves,
etc. Analogue and digital

POSITION
The necessary beam should not touch the tank
wall. Please refer Beam Angle on P-5
Do not position at the tank centre line. It causes
multiple reflections and results into incorrect
measurement. Recommendation, especially for
dome shaped tanks.

ANTENNA SELECTION
It is essential for specific application and installation requirements to be evaluated and the correct antenna type selected. The
SBEM range of radar antenna include:
4Horn and Parabolic antennas - suited for solid applications like coal, cement, food grains, etc.; also well suited for liquid
applications
4Rod antenna - specifically suited for very aggressive products - corrosive and highly condensing products
4Wave guide antenna - suitable for bullet tanks and small containers (Refer leaflet for 132 GWR LF_GuidedWaveRdr_132GWR)
Basic Criteria for Antenna selection
4Service - Solid / Liquid

4Mounting requirements
For free space applications, it is essential that
the horn extends below the nozzle. The general
rule for diameter selection is "the larger, the
better," as a larger diameter of the antenna
generates a narrower beam.

The parabolic antenna is the largest free space
antenna with the smallest beam angle. It is ideal
where the location of the nozzle is close to tank
walls, The parabolic antenna is also an
excellent choice on products with a low
reflectivity.
