Mass Flow Meters

FCI designs, manufactures and sells a broad line of air / gas mass flow meters utilizing thermal dispersion and measurement technology. Thermal dispersion technology utilizes the relationship between flow rate and cooling effect for direct measurement of mass flow. With no moving parts...


Flow And Level Switches

FCI flow switches feature thermal dispersion technology in which the temperature difference is greatest in a no-flow condition and decreases as flow increases, cooling the heated RTD. Changes in flow velocity directly affect the extent to which heat dissipates and, in turn, the magnitude of the...
