The Neptune Systems Optical Sensor is the perfect Apex accessory for constructing your own auto-top-off, as a high level warning sensor in your sump, as a water storage level sensor, and much more.
The sensor plugs into your Flow Monitoring Module and uses infrared light to signal your Apex when it changes state from being wet to dry or dry to wet.
It easy to connect to your Flow Monitoring Kit and provides reliable, easy to read reports to your Apex.
The sensors can be mounted into custom brackets or through a hole in a vessel. Included is a fastening nut and silicone washer. These sensors are sold individually.
