Flow 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 temperature difference between the RTDs.
An electronic control circuit converts the RTD temperature difference into a DC voltage signal. Both of these signals are provided at output terminals and are used to drive two adjustable-setpoint alarm circuits. Both alarms are independently field configurable for flow, liquid level/interface or temperature operation.
FCI has designed and developed four standard thermal flow switch product series to meet a broad range of performance and environmental application requirements. Each FCI flow switch group can be distinctly identified by the following listed general instrument characteristics:

Level Switches
FCI liquid level/interface switches feature Thermal Dispersion technology in which the temperature difference between the two RTDs is greatest in the absence of liquid and decreases when the level element is submerged, cooling the heated RTD.
An electronic control circuit converts the RTD temperature difference into a DC voltage signal. Both signals are provided at output terminals to drive two adjustable-setpoint alarm circuits.
Both alarms are independently field configurable for liquid level, interface or temperature operation. Since all process media exhibit different heat transfer capabilities, highly sensitive FCI liquid level/interface controllers may be specifically calibrated to detect difficult interfaces between fluids -- including liquids, gases, slurries and foam regardless of their physical properties.
FCI has designed and developed three standard thermal level switch product series to meet a broad range of performance and environmental application requirements. Each FCI level switch group can be distinctly identified by the following listed general instrument characteristics:
