ABSTRACT:
In an ultrasonic flowmeter ultrasonic signals are transmitted alternately upstream and downstream of a fluent media whose flow velocity is to be ascertained. The repetition rate at which signals are transmitted is controlled by a voltage controlled oscillator. To increase the sensitivity of the meter, the frequency of the voltage controlled oscillator, which is related to sound speed through the fluent media, is increased.
