ABSTRACT:
A vortex shedding flowmeter assembly which utilizes at least one vibrating body that is positioned in relation to an upstream facing vortex forming plate so that vibration of the body caused by vortices formed at the edges of the plate is enhanced. The body is separated from the plate so it will vibrate without causing vibration of the plate. The vibration body may be split transversely generally in the midsection of the body so that the body forms two cantilevered portions.
