This flow switch is an Industrial Standard, due to it's ruggedness and accuracy. We can calibrate it for detection of just about any flow rate that you might need. It is very common to see it in the Machine Tool and HVAC industries, but we cater to just about every market. The switch in this unit is silicone potted in a factory replaceable capsule to permit a very high vibration resistance as well as keeping it repairable in the event of failure. This model has a true globe-shaped one piece cast body that yields a lower pressure drop and minimizes turbulence while keeping the pressure capabilities very high.

Operation: Liquid flows through the housing, with flows below the "set point" the liquid flows around the shuttle, as the flow rate increases the magnet equipped shuttle starts to lift up compressing the spring until the flow rate reaches the set point in which case the magnet actuates a hermetically sealed reed switch inside the stem. Flows above the set point pass by the shuttle without issue holding the unit actuated until the flow rate begins to decrease where the spring begins to push the shuttle back down to resting position until the magnet extends far enough away from the switch causing it to de-actuate. Flow rates below the set point do not effect the unit and do not cause it to actuate.
