How does radar level measurement work?
technology
The device works according to the FMCW method (FMCW = Frequency Modulated Continuous Wave). Electromagnetic pulses in the GHz range are sent to the medium at varying frequencies between 77 and 81 GHz. Since the transmitter constantly changes the frequency of the transmitted signal, there is a frequency difference between the transmitted signal and the reflected signal. Subtract the frequency of the reflected signal from the frequency of the signal transmitted at that time, resulting in a low frequency signal proportional to the distance from the horizontal. This signal is further processed for fast, reliable and highly accurate level measurement
