Claim Text:
1. A clamp-on ultrasonic fluid flow meter system, comprising: a section of fluid flow pipe defined by a pipe wall having an outer surface and having repeating corrugations spaced at periodic intervals on the outer surface of the pipe wall, the periodic intervals of the corrugations being spaced according to a set of equations defined by: and where A and B are amplitudes of incident and reflected structure-borne ultrasonic wave signal components, respectively, Φ and Ψ are wave coupling coefficients, and x is a length of a path traversed by the ultrasonic wave within the pipe wall; and a clamp-on ultrasonic fluid flow meter having at least one transducer clamped on the pipe for measuring fluid flow within the section of fluid flow pipe.
