Flow Sensor – 2″ (FS-200)

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.

Flow Sensor – 1″  (FS-100)

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 BSPP threads so for North American customers we have included two specially designed
PVC unions with slip fittings to adapt it to standard 1″ PVC plumbing.  The FS-100 will work with flow rates from 150-1500 gph.

Flow Sensor – 1/2″  (FS-50)

Usually used with aquarium accessories like reactors, carbon/GFO filters, etc., 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 BSPP threads so for North
American customers we have included two specially designed PVC adapters with slip fittings to adapt it to standard 1/2″ PVC plumbing.  The FS-50
will work with flow rates from 30-250 gph.

Flow Sensor – 1/4″ with push-fit connectors  (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.
