ABSTRACT:
An improvement in an acoustic flowmeter of the type utilizing a pair of longitudinally spaced transceivers mounted to a fluid-carrying conduit and an oscillator feeding predetermined alternating signals to the transceivers. The improvement lies in a novel monitoring circuit which comprises a phase responsive circuit for producing signals corresponding substantially only to the phase difference between the signals produced by the respective transceivers for developing an output signal which corresponds in a predetermined fashion to the rate of fluid flow through the conduit.
