- FMM Fluid Monitoring Module - Neptune Systems
The FMM (Fluid Monitoring Module) is a multi-purpose module that, with the help of various accessories, enables your Apex to do:
- Flow Monitoring
- Leak Detection
- Water Level Detection
- Power 24VDC accessories
- Future sensors
Measuring the flow of your aquarium’s main return pump is an incredibly useful piece of information. The key benefit would be to have the Apex notify you the instant the flow stops for any reason — usually the result of a failed or faulty pump. Furthermore, an indication of a reduced flow rate could be used to determine that the pump or the lines are dirty or are becoming clogged with algae, debris, animals, or the growth of organisms inside your plumbing.
Auxiliary pumps on reactors
This is a very handy application for the FMM. Place a flow sensor on a device like a carbon/gfo/biopellet reactor and it serves many purposes. First off, you will know if your pump is not not flowing correctly or failed altogether. Next, you can easily fine-tune the flow into the reactor by watching the dashboard tile on your Apex. Finally, you can know when the reactor is becoming clogged with detritus or possibly channeling has occurred by an alert on your Apex or by monitoring your dashboard.
Put a flow sensor inline to your device, plug it into the FMM, and see exactly the flow rate of the water (any aquarium fluid really) going through that sensor. The industrial-grade flow sensors work use either a turbine or paddle-wheel mechanism (depending on the model) to measure the flow.
It is important to note that the flow rate that will be reported back to you from the flow sensors will likely be far lower than you expect or what is printed on the pump label or documentation. This is due to head pressure loss from physical height differences, long runs, restrictions such as ball valves, fittings like elbows, tees, and reducers, and then finally the loc-line many use as the entry point into their tanks. As an example, a pump rated at 3200gph will likely be showing less than half that amount in nearly all applications.
With the FMK – Fluid Monitoring Kit you get one 1″ Flow Sensor as well as two 1/2″ Flow Sensors. For North American customers, adapter fittings are also provided.
(The 1/2″ sensors are rated for flow rates from 30-250 gph. The 1″ flow sensors are rated for flow rates from 150-1500 gph.)
ONE PORT FREE – ADD ANOTHER SENSOR!
The FMK comes with three flow sensors but the FMM has a total of four ports. This means you have one port free to use for another purpose. Buy additional flow sensors (available also in 2″ and 1/4″ sizes) or choose from one of the options below and add even more functionality!
OPTICAL WATER-LEVEL SENSOR (OPTIONAL)
There are many useful purposes for water-level sensors on an aquarium. They can help you build an auto-top-off, monitor the levels in your supplement containers, even help automate saltwater mixing containers. Traditionally float switches have been the most commonly used types of these devices, however they are prone to all kinds of failure. On the other hand, the solid-state, optically-controlled sensors used with the FMM are much more reliable and dependable.
These optical sensors work by using an LED emitter and receptor in a clear enclosure such that when it becomes wet, the light bends and no longer completes the circuit.
Easy to use
Of course you could always add water-level sensors to your Apex – but it was more complicated than most users could handle. Now, with the FMM and these optical water-level sensors, you just plug them in! No wire-stripping, no breakout box necessary!
LEAK DETECTION (OPTIONAL)
In addition to flow monitoring and level-detection, the FMM can be used for leak detection. Simply plug in up to four of our new, super-sensitive leak detection probes and place them where you want that oh-so-important protection for your floors, and your marriage! There is one sensor for solid surfaces and another slimline version for use under carpets.
DC24 ACCESSORY PORT BUILT-IN!
The FMM has another trick up it’s sleeve. In addition to the four sensor ports, the FMM also has a DC24 accessory port and a power supply input. This adds another controllable outlet to your Apex set up. So, for instance, if you do want to make your own ATO and attach our available PMUP or Solenoid Valve, you can do so. Simply add our 36W 24V DC power supply (available separately).

Another Beautiful Addition to My Apex By Brett on 2/4/2019Brett would recommend this product to a friendSet up was easy, plug and play.
Poor design By Luis on 10/27/2018Luis wouldn't recommend this product to a friendDifficult to set level without triggering alarm mode/once in alarm mode the system stopped monitoring and reset was required/reset is done by unplugging-not smart
Don't build a tank without one! By Brian on 8/12/2017Brian would recommend this product to a friendI got out of the hobby for a few years because I was travelling too much and afraid to leave my tank alone but with Neptune's Apex and modules I can fully monitor my tank all the time. The FMM takes care of controlling my top off tank and shows me when my flow rates are off. I actually have two FMM modules now so I can monitor leaks as well. Easy to program and use.
Do you need a power supply if you have the Apex "Classic"?
You will not need a separate power supply from the Aquabus cable if you are just using this module for monitoring. However, if you plan to power accessories, you will need a power supply and plug this into the power port.
