Fluid.iO float switch

The QFS-10 is a cylindrical float switch made of polyethylene. Depending on the medium, the connection cable is available in PVC, Teflon, silicone, or TPK.

By selecting the appropriate combination of float and cable, the QFS-10 is suitable for use with aggressive substances. The QFS-10 can be mounted through the tank wall using a 1" bulkhead fitting with a PVC gland. If top mounting is required, this can be achieved using the G-902 counterweight or simply by attaching the cable to a pipe or the tank wall at the desired switching level. When the float reaches the horizontal position, the reed contact is actuated and the switch operates.
