This Standard gives guidelines for the selection, installation, calibration, and operation of Coriolis flow meters for the determination of mass flow, density, volume flow, and other related parameters of flowing fluids. Coriolis flowmeters cover a family of devices with varying designs that depend on the Coriolis force generated by the fluid (liquid or gas) flowing through oscillating tube(s). The primary purpose of Coriolis flowmeters is to measure mass flow. However, some of these flowmeters also measure liquid density and temperature of the oscillating tube wall. From the measurements, the mass flow of liquid or gas, liquid density, liquid volume flow and other related quantities can be determined.
