Abstract of the Disclosure A fluid flowmeter includes a bluff body for producing vortex shedding free of intermittency. The body has at one end a support member for mounting in a conduit and has proximate its downstream surfaces a pair of orifices. A diaphragm, preferably ferromagnetic, is situated in a sensor chamber within the support member for vibrating in response to received pressure fluctuations. A magnetic detector is situated in proximity to the diaphragm for producing an electrical signal when the diaphragm vibrates in response to vortex shedding. Fluid in the conduit, and thus vortex shedding, is coupled from the orifices through a pair of channels, which are in nonfluid flow communication with one another, to opposite sides of the diaphragm.
