摘要：An ultrasonic transducer assembly includes a proximal end and an opposingdistal end. The transducer assembly includes an outer housing and an electroacousticsignal generating element secured within the outer housing. The signal generatingelement transmits an ultrasonic signal at a characteristic frequency along an ultrasonic
path that is perpendicular to the face of the generating element. An isolation diaphragmis coupled to the proximal end of the outer housing. The isolation diaphragm is thinrelative to a characteristic wavelength of the diaphragm material. A fluidic transmissionlayer is disposed between the electroacoustic signal generating element and theisolation diaphragm. In one embodiment, the isolation diaphragm is at an angle relativeto the proximal face of the electroacoustic signal generating element. In anotherembodiment, a flow meter includes the ultrasonic transducer assembly, and the isolationdiaphragm substantially matches the contour of the flow passage within the flow meterbody.
