Why measure mass flow instead of volume?
Because mass is virtually unaffected by changes in pressure or temperature. Micro Motion Coriolis mass flowmeters measure mass directly. In contrast, volumetric flow measurement technologies such as differential pressure, positive displacement, turbine, or vortex, must perform pressure and temperature compensation to calculate mass. Each form of compensation introduces possible errors into the measurement and additional breaks in the customer piping (potential leak points). As well, Coriolis meters require no flow conditioning or straight piping runs, thus eliminating installation costs. They are generally the highest turndown devices found in Industry.
