Description
Neptune LLS Liquid Level Sensor 15 inch
The Neptune LLS Liquid Level Sensor 15 inch is a continuous liquid level sensor for reef and aquarium keepers who want to monitor water depth in sumps, ATO reservoirs and more. It lets you track evaporation, consumption and dosing levels, and it works with compatible Neptune Apex controllers. Because it reads depth along its full length, you see the actual liquid level rather than a simple "present or not" signal.
Key Benefits
- Brand new, first-of-its-kind, industry-exclusive sensor technology.
- Continuous monitoring of water level depth, not just detection at one fixed point.
- Track evaporation, consumption, dosing levels and more.
- Readings are given in both centimetres and inches.
- All data can be tracked in the Neptune Fusion app and displayed as a graph or as visual animations.
- Set your Apex to send an alert or take action whenever the liquid level changes by a specified amount.
- A mounting clip is included.
How It Works
Most liquid level sensors only detect whether liquid is present or absent at a predetermined sensor height. The LLS is different. It is one continuous vertical sensor that can identify the exact depth of a liquid, in both inches and centimetres, at any given time. This finer sensitivity helps you spot and be alerted to changes in evaporation, consumption and dosing levels.
How to Use
- Use the sensor in sumps, ATO reservoirs, AIO tanks, dosing containers, mixing stations and similar setups.
- Connect it to a compatible Apex (see Compatibility below).
- Follow the level in the Neptune Fusion app, which shows measurements as digital readouts and animated visual readouts so you can watch the liquid level over time.
- Configure your Apex to send alerts or take action when the level changes by an amount you specify.
Suitable For
- Aquarists who want to automate and optimise their system with accurate level data.
- Sumps and ATO reservoirs where evaporation and top-off consumption need tracking.
- All-in-one (AIO) tanks.
- Dosing containers and mixing stations where you want to keep an eye on how much liquid is left or being used.
Compatibility
- Works with any A2 Apex equipped with an FMM.
- Works with any A3 Apex, using either the embedded FMM ports or a separate FMM.
- Not backward compatible with A1 Apex models (Apex Classic models).

Frequently Asked Questions
How is the LLS different from a standard float or optical level switch?
Most level sensors only detect whether liquid is present or absent at a set height. The LLS is a single continuous vertical sensor that reports the exact liquid depth in inches and centimetres.
Will it work with my Apex Classic?
No. The LLS is not backward compatible with A1 Apex models (Apex Classic).
Which Apex models can I use it with?
It works with any A2 Apex that has an FMM. It also works with any A3 Apex, using either the embedded FMM ports or a separate FMM.
Where can I use it in my system?
It suits sumps, ATO reservoirs, AIO tanks, dosing containers and mixing stations, among other applications where you want to monitor liquid depth.
Can it alert me when the level changes?
Yes. You can set your Apex to send an alert or take action whenever the liquid level changes by a specified amount.
Does it come with a way to mount it?
Yes, a mounting clip is included.
