ABSTRACT:
The transducers in a transit time clamp-on flowmeter are positioned relative to one another by abutting against pin stops located in selected openings of one or more rows of openings extending longitudinally along the pipe axis. A block or strip of sonic-energy absorbing material is fixed to the conduit surface between the spaced transducers and absorbs sound energy which tends to flow in the pipe wall between the transducers, substantially improving the signal-to-noise ratio of the flowmeter system.
