The RSF50 series from Cynergy3 are compact vertically mounted devices with a single switch point. Mounting is in the top or bottom of the tank from the inside, so access to the inside of the tank is required. Typical applications include printing systems and chemical dosing equipment. They are manufactured in a variety of materials, with a choice of gasket materials to suit most commonly used liquids. The switch action may be reversed by removing the float, inverting it, and then refitting it to the stem. All types are also available with 1/8" NPT tapred thread.
