FMM - Fluid Monitoring module

The FMM (Fluid Monitoring Module) is a module that connects to any Apex (Apex 2016, Apex Classic, Apex Gold)
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.

The FMM 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

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.

Auxiliary pumps on reactors and the like
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 in to the FMM, and see exactly the flow rate of the water

(any aquarium fluid really) going through that sensor. The industrial-grade flow sensors 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. 

(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).

FMM Accessories

Flow Sensor – 2″ (FS-200)

Usually used with a return pump, this flow sensor can be placed in line with the flow on any pipe, connected to the FMM,
and communicate to your Apex the flow rate of water through that pipe. The flow sensor itself uses British Standard Parallel

The FS-200 will work with flow rates from 300-3000 gph.

Flow Sensor – 1″  (FS-100)

Usually used with a return pump, this flow sensor can be placed in line with the flow on any pipe, connected to the FMM,

and communicate to your Apex the flow rate of water through that pipe. The flow sensor itself uses BSPP threads so for

The FS-100 will work with flow rates from 150-1500 gph.

Flow Sensor – 1/2″  (FS-50)

Usually used with aquarium accessories like reactors, carbon/GFO filters, etc., this flow sensor can be placed in line with

the flow on any pipe, connected to the FMM, and communicate to your Apex the flow rate of water through that pipe.

The FS-50 will work with flow rates from 30-250 gph.

Flow Sensor – 1/4″ with push-fit connectors  (FS-25)

Usually used with aquarium accessories like RODI inputs, calcium reactor feed lines etc., this flow sensor can be placed

in line with the flow on 1/4″ tubing, connected to the FMM, and communicate to your Apex the flow rate of water through

that pipe. The flow sensor itself uses push-fit connectors to make connecting to your system as simple as possible.

The FS-25 will work with flow rates from 3-12 gph.

Optical Level Sensor  (OS-1)

This sensor plugs into your FMM and, using reflected infrared light, will signal your Apex when it changes state from

being wet to dry or dry to wet. This sensor can be used for constructing your own ATO (auto-top-off), as a high-level

warning sensor in your sump, water storage level sensor, and much more. The sensors can be mounted into custom brackets

or through a hole in a vessel. Included are a fastening nut and silicone washer. 

These sensors are sold individually.

Leak Detection Probe for use under carpet  (LD-1)

Plug this probe into your FMM and then place it underneath your carpet near your aquarium. Upon contact with

water this probe will communicate to your Apex and alerts or other actions can then take place. Don’t have carpet,

see the next probe listed here.

Note: The LD-1 will only work with the FMM and cannot be used with the ALD module.

Leak Detection Probe for solid surfaces  (LD-2)

Plug this probe into your FMM and then place it on any surface where you want to detect stray water.

Upon contact with water this probe will communicate to your Apex and alerts or other actions can then take place.

Time is so critical when it comes to water on the floor so it is very common to place two of these inside
the stand and two outside the stand to have the ultimate protection against a leaky aquarium. 

Note: The LD-2 will only work with the FMM and cannot be used with the ALD module.

PMUP (Practical Multi-purpose Utility Pump)

The PMUP is a 24VDC submersible pump that was designed to directly connect to the DC24
