35 Inch LLS Liquid Level Sensor

Neptune Systems LLS – Liquid Level Sensor delivers continuous, precision water level monitoring for advanced aquarium automation. Unlike traditional float or optical sensors, the LLS measures exact vertical depth in real-time, allowing you to track evaporation, monitor dosing consumption, and detect system anomalies with confidence. Compatible with Apex A2 and A3 Series controllers, it integrates seamlessly with Apex Fusion for live data visualisation, historical trend analysis, and custom alerts. The 35-inch sensor suits tall reservoirs, mixing stations, and deep sumps. Ideal for ATO systems, dosing containers, and sump monitoring, the LLS transforms reactive maintenance into proactive control. Mounting clip included; FMM Module and Apex Controller sold separately.
