The Neptune MOS Magnetic Optical Sensor offers modern and compact water level monitoring with precise control. It features a built-in magnetic mount, is silicone-encased for waterproofing, and fits into tight spaces. The design ensures it prevents water incursion into the sensor and it is suitable for glass or acrylic up to 1/2" thick. The sensor can signal changes in water state and can be used for auto-top-off systems or as a high-level warning sensor in sumps.
