Viscous and sticky liquids can stop a float switch in its tracks. The NLS is the answer.
Long Life
With few moving parts, only a flexing diaphragm, the NLS pneumatic point level sensor lasts long and is very reliable.
Low Power Operation
The NLS requires no power to operate it sensing elements, and provides a dry contact output.
Field Adjustable
Install a ½ in. pipe of your choosing in the bottom of the sensor housing, protruding past the switch point in the tank. The switch point is easily adjusted by your choice in pipe length.
