ULTRASONIC FLOW METER USING SIMULTANEOUS TIME-OF-FLIGHT AND DOPPLER METHODS

An ultrasonic flow meter system includes transducers arranged with respect to a conduit to define at least one chordal path through fluid flowing in the conduit, and at least one transmitting transducer and receiving transducer pair on the chordal path for generating a transit time signal. At least...

More Information
Summary:An ultrasonic flow meter system includes transducers arranged with respect to a conduit to define at least one chordal path through fluid flowing in the conduit, and at least one transmitting transducer and receiving transducer pair on the chordal path for generating a transit time signal. At least one receiving transducer is positioned to receive scattered energy to generate a range gated Doppler signal. The system further includes a processing subsystem for exciting the at least one transmitting transducer. The processing subsystem is responsive to the transit time signal and the range gated Doppler signal and configured to generate a velocity profile and a mean velocity of the fluid in the conduit.
