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

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.
