THE ULTIMATE MULTIPURPOSE FLUID-MONITORING DEVICE!
The FMM has four ports where you can plug in various sensors and accessories (all sold separately). The best part is that they do not need to all be of the same type. This means if you want to have a flow sensor in ports 1 and 2 and then a leak detection probe in ports 3 and 4 – NO PROBLEM! Want a flow sensor for your return pump, an optical sensor for emergency sump level detection, and two leak detection probes, NO PROBLEM! Just plug them in and the FMM will automatically sense which type of sensor you have in each port.

THE ULTIMATE MULTIPURPOSE FLUID-MONITORING DEVICE!
The FMM (Fluid Monitoring Module) is a multi-purpose device that, with the help of various accessories, enables your Apex to do:

  • FLOW MONITORING
    • With the various flow monitoring sensors you can monitor the flow inside the pipes of your return pump, emergency drains, reactor pumps, RODI feed, and much more.
  • OPTICAL WATER LEVEL SENSING
    • Attach one to four optical water level sensors and you can detect the rising or falling water levels in such applications as: water level in your sump, a low-water level in your ATO reservoir, a full skimmate waste container, or many other possibilities.
  • DETECT LEAKS AND STRAY WATER
    • Plug in up to four leak detection probes and know you have a problem BEFORE it becomes a REAL problem!
  • POWER ACCESSORIES LIKE PMUP AND SOLENOID VALVES
    • Provide an external 24V power source to the FMM and the DC24 power connector on the FMM can switch on and off devices like our PMUP, Solenoid Valve, or your own
  • OPEN THE DOOR TO FUTURE POSSIBILITIES
    • The FMM was designed such that it will be able to morph into other roles as possibilities open up – either directly from us – or from third parties.
  • WORKS WITH ALL APEX MODELS!
    • The FMM works with the Apex (2016), Apex Classic, Apex Lite, and Apex Jr. Systems.

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 can be used to add another controllable outlet to your set up. So, if you do want make your own ATO and attach our available PMUP or Solenoid Valve you can do so. Simply add our 36W 24V DC power supply.
