Abstract
The clamp-on ultrasonic fluid flow meter system is an apparatus that includes structures that filter out a pipe structure-borne ultrasonic wave component. The clamp-on ultrasonic fluid flow meter system provides pipes that are modified to rely on Bragg resonance to attenuate the pipe structure-borne ultrasonic wave component. In a first embodiment, the fluid flow pipe is modified with corrugations so that the periodicity of the corrugations defines a pipe wall corrugation wavelength that is one-half the wavelength of the structure-borne ultrasonic wave component, satisfying Bragg's condition and preventing propagation of structure-borne noise that might interfere with the ultrasonic fluid flow meter. In a second embodiment, a pipe clad material having periodic corrugations as described above is adhesively or magnetically attached to the fluid flow pipe. In a third embodiment, alternating materials at a periodic rate satisfying Bragg's condition are attached to the exterior of the fluid flow pipe.
