An ultrasonic transducer apparatus is provided. In one embodiment, the apparatus includes an ultrasonic flow meter (38, 92, 132) having an ultrasonic transducer assembly (50) coupled to a meter body (94, 134). The ultrasonic transducer assembly can include an ultrasonic transducer (112) in a transducer housing (52, 72, 74), and the transducer housing can be positioned within the meter body such that, during flow of a fluid through the meter body, the transducer housing is exposed to, and is in pressure balance with, the fluid. The transducer housing can be positioned in a sheath that acoustically isolates the ultrasonic transducer and its housing from the meter body. Additional systems, devices, and methods are also disclosed.

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. 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. 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.

An apparatus for determining a fluids kinematic viscosity from ultrasonic energy that has passed through the fluid of unknown viscosity along an acoustic path of known length. A computer of the apparatus determines a characteristic frequency of a received electrical signal associated with the ultrasonic energy and measures the fluids velocity of sound. The kinematic viscosity of the fluid is determined by the computer on a continuous basis based on the characteristic frequency and the sound velocity. A method for determining a fluids kinematic viscosity.
