Abstract
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.

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

An ultrasonic flow meter system comprising:
- two transmitting transducer and receiving transducer pairs arranged with respect to a conduit to define two chordal paths through fluid flowing in the conduit;
- at least one transmitting transducer and receiving transducer pair arranged on the conduit to define a diameter path and for generating a transit time signal;
- at least one of the receiving transducers positioned to receive scattered energy to generate a range gated Doppler signal;
- and
- a processing subsystem for exciting the transmitting transducer and responsive to the transit time signal and the range gated Doppler signal.
