Radar water level meter, also called water level radar, is an electronic device that uses electromagnetic waves to detect targets. Its main role is used for water monitoring, sewage treatment and flood warning.
The main measurement principle is to transmit radar pulses from the radar water level sensing antenna, the antenna receives the pulses reflected back from the water surface, and records the time T. Since the propagation speed C of the electromagnetic wave is a constant, thus deriving the distance to the water surface D.
Radar Water Level Gauge is an electronic device that utilizes electromagnetic waves to detect the target. The electromagnetic wave is emitted to irradiate the target and receive its echo, thus obtaining information such as the distance from the water level water flow to the point of emission of the electromagnetic wave, the rate of change of the distance (radial velocity), the bearing, and the height.
