*	Water flow sensor compatible with your Neptune Systems Apex Flow Monitoring Module
*	Place in line with the flow of 1" pipe to send flow data directly to your Apex unit
*	Perfect for use on return pumps to monitor flow rate vital to overall aquarium health

The Neptune Systems 1" Flow Sensor with Unions pairs with your Flow Monitoring Module and your Apex unit to measure water flow. It's perfect for use with a return pump and can help you determine if your flow rate is where it needs to be, making it easier to determine if your pipe is dirty or clogging with any kind of debris.

It can be placed in line with the flow on any pipe and connected to the Flow Monitoring Module then it will communicate the flow rate of water through that pipe to your Apex.

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.
