RSF150 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. These can be manufactured in a variety of plastics, with a choice of gasket materials, to suit most commonly used liquids.
