A flanged vortex flowmeter is connected to a flanged piping system that has a diameter larger than the diameter of the measurement section of the vortex flowmeter border. The vortex flowmeter has an inlet flange that reduces diameter from the inlet to the measurement section. A bluff body positioned in the measurement section produces vortices that alternate at a frequency proportional to the flow rate of fluid through the flowmeter. A length from inception of vortex shedding at the bluff body to a first expansion of the flow passage downstream of the bluff body is greater than a vortex wavelength of the vortices produced by the bluff body.

Flanged reducer vortex flowmeter

A vortex flowmeter measures process fluid flow. The vortex flowmeter includes a conduit that carries the process fluid. A sensing device is housed in a cavity of a sensor body that is coupled to the conduit. A flexure is disposed in a portion of the conduit. The flexure is configured to isolate the process fluid in the conduit from the sensing device. A pathway extends from the cavity to an outer surface of the sensor body.
