4-20mA Radar Tank Level Gauge RS485 Radar Level Transmitter
Application
- River water level measurement
- Lake water level measurement
- Shallow water level measurement
- Hydrographic survey
- Environmental protection
Configuration of flange
Because the double cable needs to be fixed, the mounting flange
must be greater than or equal to DN100, and the size of the
mounting flange has negligible effect on the signal.
Selection and Installation of Guided Wave Radar
1.For the selection of the range, the end of the probe or weight is
5cm from the bottom of the tank More appropriate.

Radar Water Level Gauge Working Principle
The radar level gauge is a measuring instrument based on the
principle of time travel. The radar wave runs at the speed of
light, and the running time can be converted into a level signal by
electronic components. The high-frequency pulse emitted by the
probe propagates in space at the speed of light. When the pulse
encounters the surface of the material, it is reflected and
received by the receiver in the instrument, and the distance signal
is converted into a level signal. It is suitable for non-contact
continuous measurement of the level of liquid, mud and granular
materials, suitable for large changes in temperature and pressure;
where there are inert gases and volatilization.
Radar Water Level Gauge Principle Structure
The radar level gauge is mainly composed of electronic components
and antennas, without moving parts. Few failures during use. The
occasional problem encountered in use is that some volatile organic
compounds in the storage tank will crystallize on the horn or
antenna of the radar level gauge, which requires only regular
inspection and cleaning, and less maintenance, as shown in Figure
1.
