FMK Flow Monitoring Kit

START MONITORING FLOW IN YOUR AQUARIUM
THIS KIT INCLUDES:

• 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 1/2'' FLOW SENSORS (FS-50)
• 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. Two of these are included in the FMK. These sensors are perfect for attaching to devices such as media reactors, biopellet reactors, etc.
• 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!

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. 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.)
