Neptune Apex Flow Sensor – 1/4″ (FS-25)

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.
