Abstract
An ultrasonic flow meter comprises a cavity disposed in the wall of a flow tube. This cavity is preferably elongated along a direction perpendicular to a flow axis and has a flat interior surface portion proximal an interior surface of a wall of the flow tube. A piezoelectric transducer has a surface bonded to the flat interior surface portion of the cavity so as to transmit and receive acoustic signals through a thin window in the wall of the flow tube. An encapsulant, which may be combined with other elements, such as a mechanical strengthening piece, bonds the second side of the piezoelectric wafer to a second surface of the cavity. In a particular preferred embodiment, the cavity may be a dovetailed groove cut into a wall of the flow tube.
