Explosion-proof High Frequency 80GHZ Level Meter Radar Type Water Level Sensor
The general principle of frequency modulated continuous wave radar level gauge is that the radar emits electromagnetic waves at the top of the tank, and the electromagnetic waves are reflected by the medium and received by the radar. The frequency difference δ f between the received signal and the transmitted signal is proportional to the distance R from the surface of the medium: R=C (velocity) * δ f (frequency difference)/2/K (frequency modulation slope). Due to the known speed of light C and frequency modulation slope K, the frequency difference δ f can be estimated to obtain the distance R from the radar installation position to the material surface. Then, by subtracting the spatial distance from the radar to the material surface (referred to as the empty height) from the known total height of the storage tank, the material level height can be obtained.
