How could a flow sensor be a useful addition to your system, what can you do with it, and how to configure it.
- Basic usage: Monitor flow rate(s), return pump, media reactors, UV, refugium, skimmer etc..
- Advanced usage: Monitor and Control Flow to parts of the system, in combination with 0-10v Controllable pumps.
On my system, I use it to keep a pre-set and steady amount of flow to the display from my return pump.
Why not just set the pump and forget it? Because manifold and media reactors.
I run a single return pump(Royal Exclusiv RD3 80w 10v controllable) with a manifold feeding 2x media reactors with Carbon and Phosphate Remover.
Occasionally the reactors require media change-out, or flow adjustment depending on the media, fill level, etc.
With the flow sensor configured, I can open up both reactors, or shut them off completely, within seconds the return pump will compensate up/down to adjust the flow to the desired rate.
Configuration:
1. Set Flow sensor index
2. Set Nominal Value (desired flow rate)
3. OPTIONAL: Set Alarm Threshold (Alarm if flow below this rate)
4. Set 0-10v output channel to "Constant Flow"
As I open or close any of the reactor feed valves, the P3 will adjust the flow by increasing or decreasing the 10v signal voltage to my return pump. Neat!

Can you provide a link to purchase the flow meters , I can not find on the GHL website?
Absolutely, here are the store links:

Marco, what are the I.D. of the three flow sensors?
Dennis:
- Flow Sensor 2000 l/h = 10mm (~3/8")
- Flow Sensor 5000 l/h = 20mm (~3/4")
- Flow Sensor 9000 l/h = 25mm (~ 1")
