MOBEYE Water Float Sensor:
Mobeye AC-WS-FS1 Water and Acid Float Switch The Mobeye water float switch helps you detect water and water-based liquids. When mounted horizontally, with the movable part down, rising water will push it closed. Closing the magnetic contact results in a closed loop. It is free to install the float as normally open (NO) or, conversely, as normally closed (NC). When installed as NC, water will open the float. If there is no mounting location for the float sensor, we recommend mounting an auxiliary rod, making a hole in it and attaching the float to it.
