More Detail

How does a radar level sensor work?

The radar level antenna emits a narrow microwave pulse, which is transmitted downward through the antenna.

After the microwave contacts the surface of the measured medium, it is reflected back and received by the antenna system again. The signal is transmitted to the electronic circuit part and automatically converted into a level signal. Because the microwave propagation speed is extremely fast, the time taken for the electromagnetic wave to reach the target and return to the receiver by reflection is almost instantaneous.

A: Range setting
B: Low position adjustment
C: High position adjustment
D: Blind area range

The reference surface for measurement is: the bottom surface of the thread or the sealing surface of the flange.

Note: When using the radar level meter, be sure to ensure that the highest material level cannot enter the measurement blind area (area shown in D in the figure).
