ABSTRACT:
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.
