FMM – FLUID MONITORING MODULE
IT DOES SO MUCH!
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
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.

FLOW SENSORS
Return pump
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.
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).

Additional Information:
FMM - FLUID MONITORING MODULE
The FMM (Fluid Monitoring ModulE) is a module that connects to any Apex (Apex(2016), Apex Classic, Apex Lite, Apex Jr.) via it’s AquaBus port providing four multi-function monitoring ports that can be used for flow sensors, water-level sensors, leak detections sensors and possibly future products as well.
1'' FLOW SENSOR (FS-100)
This flow sensor connects to the FMM, monitors the flow of water through the device, and then reports it back to your Apex via the FMM. This sensor is most often used to measure the flow in the main return line of a standard-sized aquarium.
TWO 1'' UNIONS
To connect your FS-100 Flow sensor, we have included in the FMK, two 1″ BSPT -> 1″ Slip PVC Unions. (North American markets only)
FOUR 1/2'' ADAPTERS
To connect your two FS-50 Flow sensors, we have included in the FMK, two 1/2″ BSPT -> 1/2″ Slip PVC Adapters. (North American markets only)
WORKS WITH ALL APEX MODELS!
That’s right, whether you have the new Apex, Apex Classic, Apex Lite, or Apex Jr., they all will work with the FMK!
