scope:

This International Standard gives guidelines for the selection, installation, calibration, performance and operation of Coriolis meters for the determination of mass flow, density, volume flow and other related parameters of fluids, synonymous for liquids and gases as a first approach. For gases, it gives the determination of gas mass flow and standard volume flow (using predetermined standard density). It also gives appropriate considerations regarding the fluids to be measured.

The primary purpose of Coriolis meters is to measure mass flow. However, some of these meters offer additional possibilities for determining the density and temperature of fluids. From the measurement of these three parameters, volume flow and other related parameters can be determined.

Measurements of gas flow, in principle, are possible using any Coriolis meter if special considerations are made. Specific considerations for gas flow measurements are given in Annex E.

The content of this International Standard is primarily applicable to the metering of liquids and where possible to gas measurements.
