Know Your Flow!

1″ Flow Sensor for the Fluid Metering Module from Neptune.

The FS-100 will work with flow rates from 150-1500 gph, and will connect to any standard 1″ Slip PVC.


Usually used with a return pump, this flow sensor can be placed in line with the flow on any pipe, connected to the FMM, and communicate to your Apex the flow rate of water through that pipe. The flow sensor itself uses British Standard Parallel Pipe (BSPP) threads so TSA customers we have included two specially designed PVC unions with slip fittings to adapt it to standard 1″ PVC plumbing.
