IFW, Diaphragm Flow Switch for Non-Corrosive Liquids, 1-50 Lpm

IFW is a mechanical switch for the detection and confirmation of liquid flow.  The flow body houses a diaphragm responsive to flow rate.  A connected rod and lever mechanism triggers a micro switch at a manually adjustable set point.  An optiional light, either neon (VAC) or LED (VDC), can indicate operation.  Compatible liquids must be non-corrosive to the brass and copper alloy wetted parts and NBR or optional FKM diaphram.  Wiring method can be normally open or closed with a range of voltages.  A terminal box and CE compliance are also optional.

  • Flow ranges (lpm): 1-10, 10-20, 20-50
  • Port sizes (Rc, NPT, G): 3/8, 1/2, 3/4
  • Temperature rating (°C): -5 to 60
  • Operating pressure (MPa): 0.1 to 0.6
  • Withstand voltage: 1500 VAC (one minute)
