Abstract
A flowmeter for detecting gas flow rates in a pipe includes a container configured to be attached to the pipe having a channel through which the gas flows, and a plurality of recesses that extend through the container and a plurality of housings. Each recess has a housing which contains pressure in the channel. Each housing has a window that is in acoustic communication with the channel. The flowmeter includes a plurality of transducers, with one transducer of the plurality of transducers disposed in each recess. The transducers transmit ultrasonic signals into and receive ultrasonic signals from the channel through the window in the housing in which a transducer is disposed. The flowmeter includes a controller in electrical communication with the plurality of transducers which determines the gas flow rate through the channel by measuring transit times of signals transmitted by and received by the transducers. A housing for an ultrasonic transducer for a flowmeter which is inserted into a recess of a container that acoustically isolates the housing from the container. A method for detecting gas flow rates in a pipe. A transducer for an ultrasonic flowmeter.
