MULTIPHASIC OVERREADING CORRECTION IN A PROCESS VARIABLE TRANSMITTER

摘要

A process variable transmitter is operably coupleable to a source of multiphasic process fluid flow. The process variable transmitter is configured to obtain information relative to temperature, a reference pressure, and differential pressure across a differential pressure producer in the multiphasic process flow. The process variable transmitter is configured to calculate and/or correct for overreading based upon the reference pressure, the differential pressure and the temperature.
