Abstract: A vortex flow includes a flowtube configured to receive a flow of process fluid. A shedder bar is disposed within the flowtube and is configured to generate vortices in the flow of process fluid. A vortex sensor is disposed to sense vortices in the flow of process fluid generated by the shedder bar. Measurement electronics are operably coupled to the vortex sensor and are configured to detect an analog signal of the vortex sensor and provide a digital indication relative to the analog signal of the vortex sensor. A processor is configured to receive the digital indication and calculate velocity of the process fluid flow based on a frequency of the digital indication. The processor is also configured to measure an amplitude of the digital indication and estimate density of the process fluid based on the measured amplitude.

Abstract: 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.

Abstract: 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.
