Other AbstractThe method involves reflecting pulse energy to obtain echo signal. Guided wave radar echo signal is sampled by using a liquid level meter according to sampling frequency. Original echo signal is obtained and pre-processed. Effective wave crest section information is obtained according to the pre-processed echo signal. A shortest wave section transmission time is set. A first coordinate position is selected. Peak maximum range is determined. A second coordinate position is selected corresponding to peak. Distance between a wave guide rod and separating liquid is determined. Upper liquid level of absorbing medium is determined.
