Flow Switch, Diaphragm Style

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.
