Dwyer Instruments' Series FSW2 Free-Floating Level Switch is designed for the automation of pumps

The Mercoid Division of Dwyer Instruments introduces the Series FSW2 Free-Floating Level Switch, a mercury-free self counter-weighted floating switch designed for the automation of pumps. The polypropylene body consists of a double airtight chamber with high-pressure melted polypropylene re-injection sealing. Cable hangers are available to suit a variety of mounting applications.

The FSW2 features a mercury-free microswitch housed in a waterproof casing made of polypropylene. The position of the float changes, depending on the liquid level, determining the microswitch position, which in turn controls the operation of the pump.
