Processing of orifice plate flowmeters in DCS

2009-12-31View Original

Thread Content

To measure the mass flow rate of ammonia using an orifice flow meter (with a differential pressure transmitter), the range specified by the manufacturer for such a meter is in kg/h, and the design pressure is 150 kPa. Ammonia is a hot gas, so its pressure and temperature can change. How should this be handled in a DCS system? The transmitter outputs a differential pressure signal; I would appreciate advice from everyone. Thank you

Temperature and pressure compensation is needed; it should be carried out within the system

Just add temperature compensation in the DCS
