Working principle
Guided wave radar is a gauge based on “time and domain” principle, the radar waves run along a probe at speed of light, the running time can be converted to a level signal through electric components. The sensor emit high frequency impulse and transmit along the probe, when the impulse meets the material surface, it reflects back and is received by the receiver inside the transmitter, which converts the distance signals to the level signals.
