Neptune Systems Flow Sensor, available in 1/4″, 1/2″, 1″ and 2″ sizes.
1/4″ Flow Sensors
Will work with flow rates between 3-12 GPH. 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.
Note PVC adaptors are not included, these are supplied with Flow Sensors sold in North America only.
1/2″ Flow Sensor
Will work with flow rates between 30-250 GPH. 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 British Standard Parallel Pipe (BSPP) threads.
1″ Flow Sensor
Will work with flow rates between 150-1500 GPH. 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.
2″ Flow Sensors
Will work with flow rates between 300-3000 GPH. 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.
