  • Patent number: 8245581
    Abstract: A flowmeter for detecting fluid flow rates in a pipe includes a tube having a channel disposed in the pipe through which fluid in the pipe flows. The flowmeter includes an upstream transducer in contact with the pipe and positioned so plane waves generated by the upstream transducer propagates through the channel. The flowmeter includes a downstream transducer in contact with the pipe and positioned so plane waves generated by the downstream transducer propagate through the channel and are received by the upstream transducer which produces an upstream transducer signal. The downstream transducer receives the plane waves from the upstream transducer and provides a downstream transducer signal. The flowmeter includes a controller in communication with the upstream and downstream transducers which calculate fluid flow rate from the upstream transducer signal and the downstream transducer signal.
