View Full Version : Flow Sensors?

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?

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.

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
12/22/2014, 08:54 AM
Dennis I don't see why it's not possible.

There are 3 diff flow meters available:

Level Control Products (http://www.reefbytes.com/collections/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~)

d2mini
12/22/2014, 09:20 AM
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?

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? ;)

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

d2mini
05/11/2015, 08:55 AM
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.

Hi

these are standard Whitworth threads with these sizes:

Flow-Sensor 2000 l/h: G1/2
Flow-Sensor 5000 l/h: G1
Flow-Sensor 9000 l/h: G1 1/4

anyway, I am trying to get the matching parts for the flow-sensors, I think we can offer them soon as accessory

I can special order the gf unions but the cost is 50 per so that another 100 wasted if they don't fit.

how many people are looking for these fittings? its still being a bit difficult to acquire them but I may have the ability to do a bulk buy of them. also they have a barbed fitting and soon a slip fitting what would you be interested in. pm me with size and barb or slip fitting and I will see what I can do.

the guys that make the waveline pumps use them on their pumps. they are all made in china same as the flow sensors and its a common fitting there. it was a big pain in the *** and took over 2 months for them to send them too me. i got a set of the 1 inch and the 1 1/4 inch fittings the dc4000 uses a 1 1/4 on the inlet and a 1 inch on the outlet.

about 2 months and about 50 emails. you could try Aquarium Specialty they are a sponsor and seem to carry rlss stuff. i could most likly get more thats why i posted to see if anyone else wanted. for now i think all they have is barbed fittings i think he mentioned that they were working on slip fittings though.

PurePleX
04/25/2016, 02:46 PM
Hello!

Long time since I logged in (busy building...) - sorry for not responding to your replies/cries!

I think I can sort things out.

First some definitions:

PL-0866 - 2000 l/h: hereafter refered to as #6
PL-0867 - 5000 l/h: hereafter refered to as #7
PL-0868 - 9000 l/h: hereafter refered to as #8

Now for what size of nut that will fit the different flow meeters:

The threads of #8 fits to the nut-side of a 25 mm union (GF 721 510 107)
The threads of #7 fits to the nut-side of a 20 mm union (GF 721 510 106)
The threads of #6 fits to the nut-side of a 10 mm union (GF 721 510 103)

The #6 will also fit the nut-side of a 12 mm union (GF 721 510 104) since the threads are the same, but pipe fitting differ.

See http://www.gfps.com/appgate/ecat/common_flow/10005H/COM/en/109068/109342/109343/109351/P106104/product.html for the specs of the unions.

Now me mentioning metric sizes might be confusing at first but fear not!

A 12 mm pipe is 12 mm in diameter
A 20 mm pipe is 20 mm in diameter
A 25 mm pipe is 25 mm in diameter

Quite simple, is it not?

I will just hint that the imperial pipe sizes are a little more complicated and completely un-understandable...

If you don't want to buy the whole union (eg GF 721 510 107) you can just get the nut (http://www.gfps.com/appgate/ecat/common_flow/10005H/COM/en/109068/109342/109343/109351/P106144/product.html)
together with a suitable union end in metric (http://www.gfps.com/appgate/ecat/common_flow/10005H/COM/en/109068/109342/109343/109351/P106128/product.html) or imperial (http://www.gfps.com/appgate/ecat/common_flow/10005H/COM/en/109068/109342/109343/109351/P106149/product.html).

Should you want to connect a hose instead of a pipe, you can just glue a hose connector (http://www.gfps.com/appgate/ecat/common_flow/10005H/COM/en/109068/109342/109343/109344/P106084/product.html) instead of the pipe of the corresponding size.

Any conversion between sizes can be easily done with reducing bushes (http://www.gfps.com/appgate/ecat/common_flow/10005H/COM/en/109068/109342/109343/109348/P106062/product.html), also available in imperial sizes (http://www.gfps.com/appgate/ecat/common_flow/10005H/COM/en/109068/109342/109343/109348/P106167/product.html).

All sizes above is confirmed in my system except the #6 since I have none mounted and haven't bothered to measure it. However, info correct as per GHL datasheet delivered with the meeters.

Now you are confused at a higher level... Questions?

d2mini
04/25/2016, 03:34 PM
I would suggest you get together with Vinny, Michael and Matthias and they can have these metric to imperial parts available from the new GHL USA web store. :)

No problem - something in that end was in my mind and the purpose of the info.

I must say it's a little surprising the issue have not been solved reading the frustration in this thread. GF (George Fischer) is a ridiculously large company with zillions of products in all imaginable sizes. GHL should have no problem what so ever to get what they need in all and whatever sizes and in any version metric/imperial/hose.

As a side step: each part has an CAD that you can download from their page; making exact plans in Sketchup a breeze. For example http://cad.georgfischer.com/Default.aspx?laid=100&ArtNr=161546002 and attached screendump.

I also attach a picture showing #8 and #7 with corresponding unions nuts and union ends. Again, the union ends easily available in metric or imperial size to fit pipe or hose connector (links in first post).

Sadly I never got the sensor (because the fittings were never available) and now I'm broke. :sad1:

I need new pH and redox probes before I can splurge on a flow sensor.
I don't think my pH is really 3.83. At least I hope not! ;)

Like many here it seems that a decent flow meter, at reasonable cost, that is salt water safe is a unicorn at present...

The best thing that I have found that may work well is an ultrasound / doppler unit but these things are not cheap.

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")

I have the 9000 l/h meter, and am in need of the proper fittings. It seems that the last activity in this thread held promise. The fittings are not listed on the GHL USA website. Are these available for purchase somewhere else?

Hi Tom -
We're down to the last couple in stock, but will have a new shipment of them coming soon.

You will need 2x of each of the following:
Union Nut Collar 25mm - LINK (http://royalexclusiv.com/Spare-Parts/Mini-Red-Dragon-Red-Dragon-1-BK/screw-connection/union-nut-O-25-mm::553.html)
Bushing .75" - LINK (http://royalexclusiv.com/Spare-Parts/Mini-Red-Dragon-Red-Dragon-1-BK/screw-connection/collar-O-0-75-25-mm::564.html)

The 3/4" bushings I received from you last time worked well, but I am now upgrading my pump/plumbing and need to find a fitting that works with at least 1" PVC. I see on your website that you sell 32mm (or 1") bushings - will these work with the 25mm nut that this flow sensor requires?

I need to revive this discussion ...

Marco provided me with a solution for connecting the 9000 l/h sensor with 3/4" PVC. That was fine in my previous build, my flow was low enough that 3/4" was not an issue. I have a G25 union nut and a bushing for that nut that connects to 3/4" pvc. What I need is a bushing for that same nut that will connect to 1", but apparently that is not possible?

I am now planning to push about 1000 gph through this sensor, and 3/4" is going to be a restriction, isn't it? I know that we're converting metric pipe to fractional, so I need to compromise a bit. That said, the internal diameter of the sensor body is 1", and the threads are 1-1/4" (yes, BSPP). There has to be a way to connect this to 1" PVC ... anyone? Or do I just use a 3/4" to 1" adapter and hope that the short 3/4" restriction in the line isn't a problem?

BTW, I did try the Spears fitting mentioned earlier in this thread, and as the other poster found out, although that Spears fitting is indeed BSP, it is BSPT, not BSPP (at least that is what it seems to me).

The Apex fluid management kit has been released and from what I have read on the forums is they use the very same thread.(You should probably confirm this)
Look at suppliers for the Apex accessories (Marine depot and others) as they could possibly have stock available.

A pseudo restrictor in the line is still a restrictor, it will affect the flow through the whole line.

Thanks for that. I see that Neptune mentioned in one of their threads that they would start selling the fittings after they get caught up on backlog orders. Not sure what they meant by that - I don't think they sell direct, right?

They also mentioned that they think the Spears fitting will work, and it doesn't (at least not the 335-12). Hopefully they just sell the exact parts they are shipping with the sensors ..
