IF3 is a mechanical switch for the detection and confirmation of liquid flow.  The device threads into a flow path, where the liquid pushes against the paddle.  This actuation triggers a micro switch at a manually adjustable set point.  Short, medium and long paddles are provided with each model.  Paddle size to install will be determined by the pipe size and flow rate.  Options include IP42 or IP44 rated enclosures, and either brass / bronze or 304 stainless steel wetted parts.  Compatible fluids must be non-corrosive to these materials.  Wiring method can be normally open or closed with a range of voltages.  CE compliance is also optional.
