Claim Text:
1. An ultrasonic waveguide assembly comprising: a pipe having an exterior surface and an interior surface, the interior surface defining an inside diameter of the pipe which comprises fluid traveling therethrough; a first ultrasonic waveguide penetrating the exterior surface of the pipe and the interior surface of the pipe at a first location such that the first ultrasonic waveguide is in direct contact with the fluid traveling therethrough, wherein the first ultrasonic waveguide comprises two end surfaces and two side surfaces arranged between the end surfaces and spaced apart along a longitudinal axis of the pipe such that the two side surfaces are substantially parallel, and each of the side surfaces of the first ultrasonic waveguide contacts the pipe at an acute angle to the longitudinal axis of the pipe; a first ultrasonic transducer adapted to be acoustically coupled to a top end of the first ultrasonic waveguide at an acute angle such that the top end of the first ultrasonic waveguide is parallel to the longitudinal axis of the pipe; a second ultrasonic waveguide penetrating the exterior surface of the pipe and the interior surface of the pipe at a second location such that the second ultrasonic waveguide is in direct contact with the fluid traveling therethrough, wherein the second ultrasonic waveguide comprises two end surfaces and two side surfaces arranged between the end surfaces and spaced apart along a longitudinal axis of the pipe such that the two side surfaces are substantially parallel, and each of the side surfaces of the second ultrasonic waveguide contacts the pipe at an acute angle to the longitudinal axis of the pipe; and a second ultrasonic transducer adapted to be acoustically coupled to a top end of the second ultrasonic waveguide at an acute angle such that the top end of the second ultrasonic waveguide is parallel to the longitudinal axis of the pipe.
