Neptune Systems FMK Flow Monitoring Kit

Neptune Systems FMK Aquarium Flow Monitoring Kit

  The Neptune Systems FMK Aquarium Flow Monitoring kit provides you with accurate water flow tracking across reactors, refugiums,and return pumps. Brought to you from neptune systems as part of their expanded controllers lineup.  

Neptune Systems FMK Aquarium Flow Sensors for Reliable Data

The kit includes industrial-grade flow sensors that track water movement through plumbing. With these sensors, aquarists can measure real flow rates instead of relying only on pump labels.

• One 1" FS-100 Flow Sensor rated for 150–1500 gph
• Two 1/2" FS-50 Flow Sensors rated for 30–250 gph
• Two 1" unions and four 1/2" adapters included

 

How the Neptune Systems FMK Aquarium Flow Kit works with Return Pumps

The FMK keeps a constant watch on return pump flow as water moces through your system. If water flow drops outside the normal levels, the Apex can send instant alerts and trigger automatic responses. The result? Blockages, clogs, or pump failures get addressed quickly.

Auxiliary Pump Monitoring and Reactor Applications

Carbon, GFO, and biopellet reactors are easier to dial in with the FMK. Real flow data helps spot issues like channeling or detritus buildup before performance drops.

• Track flow into reactors for optimal efficiency
• Use Apex dashboard tiles for live readings
• Receive alerts when reactor flow diminishes

Expand the Neptune Systems FMK Aquarium Flow Monitoring Capabilities

The FMM module included in the kit provides four sensor ports, yet three are used by default. This leaves one open port for expansion. Add more sensors or other supported devices to customize the setup.

Optional Optical Water-Level Sensors

Optical sensors improve reliability over traditional float switches. Connect them directly to the FMM for quick installation. They can manage auto top-off systems, monitor supplement reservoirs, or control saltwater mixing stations.

Leak Detection Options

Plug sensitive leak detection probes into the FMM for additional protection. Choose between slim sensors for carpets or solid-surface probes for stands and tile floors. These sensors help safeguard homes and aquariums alike.

DC24 Accessory Port for Added Functionality

The FMM also includes a DC24 accessory port. Connect devices such as the PMUP utility pump or a solenoid valve with a 36W 24V power supply. This port extends automation without the need for extra modules.
