Radar level meter

- Nov 19, 2017 -

Radar level gauge is a universal radar level gauge, it is based on the principle of time travel measuring instruments, radar wave speed of light operation, operating hours can be converted into electrical signals through the electronic components. The probe sends a high-frequency pulse to propagate in space at the speed of light. When the pulse encounters the surface of the material, it is reflected and received by the receiver in the meter, and the distance signal is converted into a level signal

Measurement principle editor

Radar level gauge is based on the principle of time-domain reflection (TDR) -based radar level gauge, the electromagnetic pulse of the radar level gauge at the speed of light along the cable or probe propagation, when the surface of the measured medium, the radar level Some of the pulses are reflected to form echoes and return to the pulse launcher along the same path. The distance between the launcher and the surface of the measured medium is proportional to the propagation time of the pulse between them and the height of the liquid level is calculated.

Application Guide Editor

Radar level gauge used in water tank, acid storage tank, slurry storage tank, solid particles, small storage tank. Various types of conductive, non-conductive media, corrosive media. Such as coal warehouse, ash warehouse, oil tank, acid tank and so on
