Which Accessories Can You Use with an FMM Module? (sold separately)

Flow Sensors: 1/4″ FS25, 1/2″ FS50, 1″ FS100, 2″ FS200.

Available in four different sizes, flow sensors can be used to monitor your return pump’s flowrate or the flowrate of other equipment like UV sterilizers where a specific flow rate is required.

Optical Sensors: MOS Magnetic Optical Sensor, OS-1 Optical Level Sensor.

They can help you build an auto-top-off, monitor the levels in your dosing containers, prevent your return pump from running dry, and even help automate saltwater mixing containers.

Leak Detectors: LD-1, LD-2, LD-3.

Simply plug in up to 4 leak detection probes and place them in the area you want to be notified about.

Water Level Sensors: LLS Liquid Level Sensor.

If you need to know the specific water level, the LLS is the right tool for the job. Perfect for ATO reservoirs, dosing containers, and the return section of your sump. LLS Sensors are available in four lengths from 4 to 35 inches.

DC24 Accessories: PMUP, SV-1 Solenoid Valve.

In addition to the four sensor ports, the FMM also has a DC24 accessory port and a power supply input. If you wish to utilize the DC24 port, simply add a 36W 24V DC power supply (sold separately).
