Abstract In view of the orifice flowmeter in the process of steam measurement, due to the change of steam temperature and pressure of the measurement error is large, through the steam temperature and pressure compensation correction, reduce the instrument measurement error. Introduces the basic principle of orifice flowmeter measurement, the reason of temperature and pressure compensation for steam, the treatment method, calculation method and matters needing attention of temperature and pressure compensation, which is verified in DCS program for technicians reference.
