ELITE® Coriolis Flow and Density Meters
edge.rit.eduMicro Motion® ELITE® Flow and Density Meters 5 Liquid flow performance Mass Volume(1) (1) Specifications for volumetric flow rate are based on a process-fluid density of 1 g/cm 3 (1000 kg/m3). For fluids with density other than 1g/cm3 (1000 kg/m3), the volumetric flow rate equals the mass flow rate divided by the fluid’s density.
