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.

摘要: A process pressure fluid transmitter is coupled to a differential pressure producer and measures a differential pressure across the producer. A statistical parameter is calculated upon successive differential pressure indications, and the calculated parameter is used to indicate wet gas flow. The indication can be generated locally at the process pressure transmitter, communicated via a wired process communication loop, communicated wirelessly, or any combination thereof.
