Product Description

Guided-Wave Radar Level Meter GRD 80 series

Measurement Principles
The guided-wave radar level meter is a measuring meter basing on time-stroke
principle and the radar wave runs at the speed of light. The running time can be
converted to level signal through electronic components. The distance between
measurement reference point and material surface, the probe transmits high-frequency
impulse which transmits along the cable, and when the impulse is reflected after
encountering the material surface, it will be received by the receiver in the meter,
and the time signal will be converted to level signal.

 

Input
The reflected pulse signal transmits along the cable to the electronic circuit
part of the meter, and the micro-processor will process the signal, identify
the echo wave of microwave impulse reflected on the material surface.The
correct echo wave signal will be identified by the intelligent software, and
the distance to material level D is in direct proportion to time-stroke T of
impulse.

 D=C×T/2
 Where, C indicates velocity of light.
 Because the distance in empty tank E is known, the material level L is:
 L=E-D
 
Output
By configuring empty tank height E (=Zero), full tank height F (=full range) and
some application parameters. The application parameters will adapt the meters to
the measurement environment automatically.
