摘要： 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.

摘要： A vortex flowmeter has a vortex sensor and terminals that receive a thermal junction output from a thermowell assembly that is remote from the vortex flowmeter. The vortex flowmeter has a data input that receives data representing a thermal property of the thermowell assembly. The vortex flowmeter has a circuit that receives the first thermal junction output and the vortex sensor output, and that provides a flowmeter output that is compensated for temperature and for the thermal property.

摘要： A vortex flow meter for measuring fluid flow has a conduit for carrying a fluid. A region of reduced thickness is formed in a portion of the conduit. A shedding bar disposed in the conduit is coupled to the region of reduced thickness and is configured to apply a rocking motion to the region of reduced thickness about a pivot line in response to flow of the fluid. At least one reinforcing rib on the reduced thickness portion preferably extends parallel to flow of fluid.

摘要： A process fluid sensor for sensing a characteristic of a process fluid is provided. The process fluid sensor includes a metallic sensor body that defines a chamber therein. A piezoelectric crystal element is disposed proximate the chamber and is configured to generate an electrical signal in response to a mechanical input. The piezoelectric crystal element is mechanically coupleable to the process fluid, but is sealed within the sensor body with the exception of a gaseous pathway. A vortex flowmeter utilizing the process fluid sensor is also provided.

摘要： A process fluid measurement system provides a first measurement relative to process fluid flowing in a pipe. An additional measurement of process fluid flow velocity in the pipe is combined with the first measurement to provide a simplified indication of mass fluid flow and/or density or other fluid parameter. In some embodiments, the first measurement is a differential pressure measurement. Additionally, one embodiment provides a vortex flowmeter having configurable terminations for coupling to a variety of pressure or differential pressure sensors or transmitters for advanced process fluid measurements or calculations.
