Compensation type selection Differential pressure compensation The type is not affected by medium components or the change of dryness. It is especially suitable for measuring unstable component mixed gas, liquid, high humidity steam and water vapor contained. Temperature compensation This type is mainly suitable for measuring mass flow rate of stable pressure saturated steam Pressure compensation This type is mainly suitable for measuring standard flow rate of stable temperature gas and mass flow rate of steam. Temperature and Pressure compensation This type is mainly suitable for measuring mass flow rate of steam and standard flow of gas.
