Neptune Flow Sensor - 2" with Unions

2-10 Days

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 for North American customers we have included two specially designed PVC unions with slip fittings to adapt it to standard 2″ PVC plumbing. The FS-200 will work with flow rates from 300-3000 gph
