Flow Sensors?

[d2mini]

A long time ago there was talk of sourcing fittings that would work with USA plumbing... was this every figured out?
Or what is needed to install the flow sensors?

 

[BigAl2007]

Dennis I have a client who is literally working on this right now. I'm hoping that our efforts pan out and I will have a "connection kit" available in a few weeks.

HTH

Thanks, Al.
Where it would really come in handy for me is to measure the flow through a UV.
But we're talking flow rates of something like 1000-2000 gph.
Is this even possible?

 

[BigAl2007]

Dennis I don't see why it's not possible.

There are 3 diff flow meters available:

Level Control Products
2000 l/h
5000 l/h
9000 l/h

To be able to handle your upper amount of 2000gph you'd want to get the 9000 l/h unit (2000gph = 7571lph~)

oh cool, i think i missed that larger one last time i had looked at these.
Do you happen to know approximately what size the fittings are? My plumbing is 1.5".
I would be afraid of creating a restriction in flow if it's much smaller.

 

[BigAl2007]

See if this answers your question Dennis:

Part #PL-0868: Measurement range flow max. 9000 l/h, Nominal width DN25, 2x G1 1/4" outside thread

That's all of the "specs" I have available at the moment.

Hello!

Google "Georg Fischer 721514106" (and choose for example http://www.construnario.com/presto/921/4/424/424.gif) and you'll get an idea of what you need. The union above will have one end metric (20 mm) which you'll discard (the flow meter will instead be that end) and one end ASTM (1/2 inch). The flow meter comes with O-rings (and so does the union). The other sizes will fit the other flow meters. Works like a charm.

if you need to measure higher flows you can operate the flow sensor in a bypass

ProfiLux is able to calculate the real flow based on the bypass / main flow ratio

Thanks for the link

Unfortunately these are near impossible to come by in the USA or Canada which has always made such an important part of the GHL kit a difficult sell.

I've been using +GF+ (Georg Fischer) piping for the past few years and Grainger(International) always has stock.

This type 375 union may be what you need, no?

Thanks, I will buy one for each and test, if this is the case then we can start selling the sensors with the adapters to retailers as a kit.

Excellent help thank you.

No problem, keep me updated as i am curious myself.

 

[d2mini]

Thanks, Jerel!
And thanks AQD for testing it out. I did the google search but would still be confused on exactly what would work.

Also, Matthias mentioned using it in bypass mode.
I don't really understand how that works. Can anyone offer an idiot explanation/illustration?

I believe he means something like that.

any follow up on this? any news?

 

[AQD_ottawa]

Off to UK in July, only way to get reliable source for these I wish they were supplied with them to cater for the USA requirements. Great unit really beneficial but the connection is not North American friendly.

Once we have got ample supply of the adapter they will sell like mad I have no doubts

 

[sowildpaul]

Are they planning to make 1 1/2" flow sensors or not?

You can't use a timer and a bucket?

:lol:

 

[BigAl2007]

You can't use a timer and a bucket?

:lol:

Sure you can but how do you incorporate a bucket and timer into your ProfiLux Controller? :spin2:

 

[d2mini]

I've done the timer and bucket to get a very rough idea, if that.
But i have water coming out into the tank, into a frag tank, into a refugium and into a mangrove tank. Trying to get that accurate measurements from all that is next to impossible. It would be so much better to have a flow meter inline after my return pump.

Michael, if you can find the parts during your trip let me know!
I would love to get one of these installed, take some pics, post about it here, on my build thread, Facebook, etc.
