Neptune Systems Neptune Apex Optical Level Sensor

The Neptune Optical Sensor plugs into your FMM Module, and using reflected infrared light will signal to your Apex when it changes from being wet to dry and vice versa.

This sensor can be used for constructing your own ATO (auto-top-off), as a high-level warning sensor in your sump, a water storage level sensor, and much more. The sensors can be mounted into custom brackets or through a hole in a vessel. A fastening nut and silicone washer are included with the Sensor.
