Abstract
PURPOSE:To accurately measure the object without depending upon the variation of the amplitude of wave receiving output, by obtaining output right specifying a point of time of wave receiving output when at least one of wave receiving output vibration has amplitude exceeding a reference level. CONSTITUTION:Ultrasonic waves are emitted from an ultrasonic-wave transducer 2A, propagated in the forward direction in a fluid 4 and received by means of an ultrasonic-wave transducer 2B. Wave receiving output W is gained through a gate circuit 7. Pulses P5 acquired from a pulse generating circuit G5 are obtained as output indicating a point of time specifying a point of time when osicillatory waves forming the wave receiving output W cross a reference level as a point of time when the wave receiving output is gained, and the output is supplied to a measuring circuit 22.
