Flow Switches
FCI Flow Switches for Liquid, Air and Gas 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 temperature difference between the RTDs.
Gas Mass Flow Meters
FCI air / gas mass flow meters utilize 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 and minimal invasiveness, thermal dispersion is ideal and widely applied in air and gas applications, and provides a highly repeatable and accurate measurement.
