In industrial production, flow measurement is a crucial link to ensure the stable operation of process flow. Orifice flowmeters, as a classic differential pressure flow measurement instrument, are widely used in petrochemical, electric power, metallurgy, and other industries due to their simple structure, reliable performance, and convenient maintenance. However, facing complex working conditions and diverse measurement requirements, standardized orifice flowmeters often struggle to fully meet actual application demands. Customized Orifice Flowmeters have emerged as an effective solution to measurement challenges under special working conditions.

I. Necessity of Customizing Orifice Flowmeters

In industrial production, each application scenario has its unique characteristics. Standard orifice flowmeters Although they can meet the needs of most conventional working conditions, customization becomes particularly important when facing the following situations:
