Abstract

The present invention is a transducer (10) for sonically measuring gas flow. The transducer (10) includes a transducer body (18) defining a tube with a first end portion (3) of the tube including a damper portion for interfacing with the gas flow under measurement. The transducer also includes a membrane (12) rigidly attached to the transducer body for sealing off the transducer body from the gas flow. An actuator (6) made up of a stack of piezoelectric slices (4) is disposed in the transducer body (18) to interact with the membrane (12). An acoustic impedance matching material (8) having an acoustic impedance between the acoustic impedance of the actuator (6) and the acoustic impedance of the gas flow is disposed between the membrane (12) and the actuator (6). The transducer (10) further includes a damper assembly (20) disposed in the damper portion of the transducer body and consisting of a plurality of damping washers (30) disposed between acoustically transmitting washers (26) for damping acoustic energy through the transducer. Another embodiment of the transducer includes a reflector coupled to the first end portion for altering a direction of the acoustic energy directed to or form the transducer (10).
