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.
