ABSTRACT:
An ultrasonic measurement system for measuring a flow in a conduit. Spaced ultrasonic signal transmitters are configured to launch a ultrasonic beams having a center axis of maximum intensity. Receiving transducers are configured to receive modulated signal energy from the beams and are located off the center axis of the beams to increase the modulation of the signal energy and to produce receiver output signals. A processing subsystem is configured to correlate the receiver output signals to determine a time delay indicative of the flow velocity in the conduit.
