ABSTRACT:
A damping device for a fluid flow meter mountable on the exterior of a pipe to meter fluid flow traveling within the pipe is provided. The flow meter has at least one ultrasonic sensor operable to transmit ultrasonic signals through a pipe wall in a direction normal to the pipe wall and into a fluid flow disposed within the pipe, which signals create secondary ultrasonic signals circumferentially traveling within the pipe wall at a frequency. The damping device includes a base and a plurality of tines. The base is conformable to an exterior surface of the pipe wall, and has a pipe-side surface and a tine-side surface. The plurality of tines is attached to the base and extends outwardly from the tine-side surface. Each tine is spaced apart from an adjacent tine by a tine-to-tine distance that is less than the wavelength of the secondary ultrasonic signals circumferentially propagating within the pipe wall.
