NIVOFLOAT NL-100, NW-100 – Float-Type Level Switches

The NIVOFLOAT NL-100 series float switches are used to switch on and off at specified levels of both drinking water and wastewater. The double polypropylene housing ensures perfect watertightness, and cable lengths of 5, 10, or 20 m—available in PVC or neoprene—meet even the most demanding requirements. A mercury-free switch is built into the float and operates at a 45° angle. The NW-100 series was developed for extremely demanding applications; it features a robust design and a float volume nearly twice that of the NL series. Thanks to its larger volume, the float performs better in denser liquids. Another advantage of this series is that it functions even without a counterweight.
