26G Radar Level Meter NYRD809 Small Blind Zone High Frequency
26G Radar Level Meter Working Principle
The radar level antenna transmits narrow microwave pulses, which are transmitted downward through the antenna. When the pulse wave touches 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 pulse propagation speed is extremely fast, the time taken for the electromagnetic wave to reach the target and return to the receiver after reflection is almost instantaneous).
Measuring datum plane: the bottom surface of the thread or the sealing surface of the flange.
Note: When using the radar level timer, it must be ensured that the highest level cannot enter the blind area (area shown in D in the figure).
