Flow Sensors?

took me 1.5 years to find a source and 1.5 months for them to send me the fittings hopefully its all worth it.

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.
 
Has anyone found adapters for the flow meters. Would really like to purchase one But need the adapters.
 
*** is british standard? I thought there was just metric and standard. Yeesh. :facepalm:
GHL just needs to change it on their end. Bam. Done.
 
the flow sensors they get are made in china i believe hence the thread pattern. there is 2 different british threads too. ie 1st post on page 3

what sizes are yall looking for and ill see if i can get more in from the supplier i got mine from.

Ya, this I just don't understand. Why on earth would you produce/sell something that almost nobody seems to be able to use?!
This seems completely not thought through at all... the complete opposite of GHL.
Boggles my mind. :hmm3:
 
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/co...068/109342/109343/109351/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/co...068/109342/109343/109351/P106144/product.html)
together with a suitable union end in metric (http://www.gfps.com/appgate/ecat/co...068/109342/109343/109351/P106128/product.html) or imperial (http://www.gfps.com/appgate/ecat/co...068/109342/109343/109351/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/co...068/109342/109343/109344/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/co...068/109342/109343/109348/P106062/product.html), also available in imperial sizes (http://www.gfps.com/appgate/ecat/co...068/109342/109343/109348/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?

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. :)
I would want to buy this in kit form, not have to source parts from one country to make sure it works in my country with a device from yet another country.

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).
