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

This item must be used with a Neptune Apex controller with an FMM, it cannot be used stand alone.

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.
