Abstract
The invention relates to measuring technique, namely to the technique of measuring a motion speed and a liquid or gas flow by means of pulse acoustic signals. The purpose of this invention is the improvement of measurement accuracy of the motion speed of liquid or gas in a pipeline by means of the complete elimination of an impact of the transmission time of acoustic signals in the pipeline walls on the measurement results and a more effective compensation of its own delays of a radiation source and a receiver directly in the operational conditions of the measurements.
