Abstract

See full text

A system for measuring flow of process fluid through process piping in an industrial process includes a flow restriction element in the process pipe. A first differential pressure transmitter is configured to measure a first differential pressure across the flow restriction element in response to flow of process fluid. A second differential pressure transmitter configured to measure a second differential pressure in the process fluid across the flow restriction element. Circuitry performs diagnostics based upon the first differential pressure and the second differential pressure.
