RSF50 series are compact vertically
mounted devices with a single switch
point. Mounting is either from the top or
bottom of a tank from the inside, so
requires access to the inside of the tank.
Typical applications include vending
machines, printing systems and chemical
dosing equipment.
These can be manufactured in a variety of
plastics, with a choice of gasket materials,
to suit most commonly used liquids.
The switch action may be reversed by
removing the float, inverting it, then
refitting to the stem.
All the standard types are also available
with 1/8”NPT tapered thread mounting
(The last letter of the part number is
replaced with 1/8.)
