The FM series is designed to provide an extremely reliable flow switch at a very cost effective price. This series replaces the standard explosion proof enclosure utilized in our FX series with a general purpose enclosure.



The thermal dispersion principle of operation measures a temperature differential between a heated and a reference temperature sensor. The differential varies as flow across the sensor changes. This allows the flow switch to detect the increase or decrease of flow of virtually all liquids, gases and slurries.



The electronics feature a SPDT relay switch output with options for power input of 01020 VAC, 012VDC, and 24 VDC or VAC. Field calibration is easily performed by adjusting a potentiometer on the circuit board.
