The Neptune Systems 4" Liquid Level Sensor offers continuous, precise measurement of liquid depth within your saltwater aquarium system. Unlike basic on/off sensors, this innovative device identifies the exact height of liquid in both inches and centimeters, providing real-time data on critical levels in sumps, ATO reservoirs, AIO tanks, and dosing containers. It is designed to help aquarists proactively monitor and manage water changes, consumption, and dosing.

This industry-exclusive sensor enables comprehensive tracking of evaporation, consumption, and dosing levels over time, with all data viewable in the Neptune Fusion app through digital and animated visual readouts. Measurements are displayed in both centimeters and inches. Users can configure their Apex controller to send alerts or trigger automated actions whenever the liquid level changes by a specified amount, ensuring prompt response to any fluctuations. A mounting clip is included for easy installation.

Ideal for serious reef keepers and those with automated systems, this sensor is perfect for anyone seeking unparalleled accuracy in liquid level monitoring to optimize their setup. It allows for advanced automation and provides peace of mind by preventing potential issues related to low ATO water, depleted dosing solutions, or unexpected water level drops. This product is invaluable for maintaining stability and efficiency in any modern reef aquarium.
