とを特徴とする超音波式流量測定装置。A measurement device that detects the difference in propagation time of ultrasonic pulses emitted in the forward direction and the reverse direction with respect to the flow of the fluid to be measured, and measures the flow rate of the fluid to be measured based on this time difference, the oscillator A counter counts the oscillation pulses of a constant frequency oscillated by the counter, and when the counted value reaches the set value, the backward propagation time measurement cycle ends, and the next forward propagation time measurement cycle is performed in the same way. In this measuring device, a timer element is provided which is actuated by the output signal of the counter and emits an output signal for a certain period of time, and while the timer element is in operation, the output signal causes the oscillation pulse of the oscillator to be controlled. An ultrasonic flow rate measuring device characterized in that the ultrasonic flow rate measuring device is configured such that the flow rate is not guided by the counter.
