FMA-1618A-B

FMA-1600A series mass and volumetric Omega's flow meters use the principle of differential pressure within a laminar flow field to determine the mass flow rate. A laminar flow element (LFD) inside the meter forces the gas into laminar (streamlined) flow. Inside this region, the Poiseuille equation dictates that the volumetric flow rate be linearly related to the pressure drop along a fixed distance of the LFE. This, along with the viscosity of the gas, is used to accurately determine the volumetric flow rate. Separate absolute temperature and pressure sensors are incorporated and correct the volumetric flow rate to a set of standard conditions.
