Abstract

The current methods for measuring ultrasound propagation time are based on the formation and further measurement of the time interval between the radiation and locked-on signal equal to the time of the sound propagation. The mechanism of this interval formation is determined by the circuit of the control and construction of the measurement converters. To ensure high accuracy of the measurement of the acoustic oscillations propagation time, all functional units have to meet the needs of the temperature and time stability.
