The one thing I have always wanted to have with my controller is a flow meter. Any chance you guys might or could come up with one? Thanks for a great product!!

That would be cool I've seen aftermarket ones but they don't integrate into the apex

I know it's late but not getting why you would want to measure flow all the time?
To see if the pipes are clogging, pump is dying or just plain see if everything is running.
This is just off the top of my head and I'm new to the apex but could you use a float switch sideways in a pipe or something like that? It couldn't measure flow but it would know when there is or isn't flow right?

That feature is available on the DOS and WAV that they announced at MACNA. If Neptune makes a DC return pump (If you are watching Terence, I would call it FLOW), then I am sure a flow meter will be incorporated into that.
You might be an engineer if...You have no life and can PROVE it mathematically.

This switch should do the work with a little modification .

That would do the trick. I would find one that uses the same size fittings as your return though and less modification would be needed.

Thats a pressure switch, not flow meassurement.

Yes, but it serves the same purpose if the user wanted a flow meter for the purpose of changing outlet behavior if return flow was less than a certain amount. If the user wants flow metering as a way to determine when preventative maintainance needs to be done, it would not serve that purpose.Originally Posted by AndreasK
this sounds better for me. Sorry, may I had a language issue.

You were correct even with the language barrier, but there is more than one way to determine when a return stalls or a pipe gets clogged.
1. If an actual flow meter was available, you would know that normal flow is X gph in the forward direction. If flow reduces by 10-20%, then you know you need to clean the pump or pipe, and if its close to zero, you know something failed or clogged.
2. You can use a pressure switch. If the return is on, there will be a large pressure in the pipe that tells you it is running properly. If output reduces because its dirty, it will still read as okay because its still running. But as soon as the flow stops, the pressure goes to zero and you know there is a problem.
3. You can use sump water level. If the return is on and the water level in the sump rises, it means either the ATO overfilled, or the return pump failed. You also know that if the normal level float shows open and the upper level float shows open then the ATO wasnt the culpret, so indirectly you can determine return pump failure or clogging with this code.
Set OFF
If HighSw OPEN Then ON
If ATOSw CLOSED Then OFF
If Outlet Return = OFF Then OFF
Defer 001:00 Then ON
Would a unit like a boat speedo work? A water wheel in a tube. Probably not made. But might be an easy DIY. Is the Grey conduit reef safe? If so, the wheel could be installed on a small junction. Just a thought
Do you mean schedule 80 PVC when you say Greg conduit? If so, yes that is reef safe. Almost all plastics are reef safe with the exception of number 1 plastics and number 7 if heated above 100 F.
S40 rigid conduit.
There are many types of rigid conduit. PVC, galvanized steel, EMT, liquidtight, etc. If its made of metal its not reef safe.
S40 rigid pvc sorry
Rigid PVC is fine.
So the DIYing a boat speedo might work if wanted. I just keep my tubes/pipes/pumps clean and maintained regularly. I basically can take all my plumbing apart in 3' chunks and brush them. I can run one return pump while one is down so nothing is to crazy for long.
Maybe, maybe not. I see clogging as a very possible issue and adding the instrumentation without exposing any internals to saltwater and detecting a loss of flow are not going to be easy.
The speed sensor on a boat is exposed to the salt. I'm thinking a guy could cut a slot for the water wheel to sit through the removable top and epoxy it on with the wheel through it. When the water passed by it would spin the wheel. Hence flow rate. No?
