Abstract:
The present invention provides an ultrasonic flowmeter comprising an oscillator and an oscillation start unit for accelerating oscillation of the oscillator. The oscillation start unit accelerates the oscillation of the oscillator so that pulses from the oscillator will become stable in a shorter time period. The accuracy of flow rate measurement is improved. Electric power can be saved where the flow rate is measured repeatedly at intervals.
