Operation
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 principle of operation measures a temperature differential between a heated and a reference temperature sensor (see figure 1). 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. Flow ranges are shown on the next page of this brochure in the set-point range chart. A conversion chart is also provided to covert volumetric flow to velocity.
The electronics feature a SPDT relay switch output with options for power input of 120 VAC, 12VDC, and 24 VDC or VAC. Calibration is easily performed by adjusting a potentiometer on the circuit board.
