Tips: How does a radar level sensor work?
The working principle of radar level sensor is based on TDR technology, which is based on pulses of electromagnetic energy transmitted along the probe tube. Therefore, when the radar pulse reaches the surface of the liquid in the processing tank with a higher dielectric constant than air, the pulse will be reflected back to the electronics unit. Equipped with a high-speed electronic timing circuit, it can calculate the passing time and measure the liquid level in the tank. It can accurately measure the liquid level.
