Help Uk Flowmeter regulator for Nitrogen Exit bag method ?

[PierreWolf]

Hello everyone,

I have a quick question and would love some help with it!

I live in the UK and I'm in the process of setting up my Nitrogen Exit bag method. I've got pretty much everything by the Flowmeter regulator.

Here are the ones I've found so far but I'm wondering if they are the rights ones for this method:

Nitrogen/Helium/Air 230 bar BS3 two stage regulator - two gauge 0-10 bar

Suitable for all cylinders and packs up to 230 bar with a BS341 No3 (5/8"" right hand thread) outlet connection. This two-stage regulator is suited for all inert (Argon, Helium and Nitrogen) gases/mixtures. There are two gauges, an outlet delivering 0-10 bar and a maximum flow of 100 m3/h).

Would any of these ones work with a Nitrogen gas bottle UK fitting BS 341 No. 3?

If not, does any of you know where to found a flowmeter regulator that would fit BS 341 No. 3 ?

Does it matters if it's a single stage regulator or do you need a two stage one?

Thank you very much

I'm not in the UK.. but no 1 & 3 are regulators and they are BS 341 No 3 connections. They would connect to any Inert gas cylinder.

The no 2 link is for a flow meter that would come after the regulator....it would be in-between the regulator and the final delivery.
It would give data on the flow in this case Liters per minute. This particular one appears to be calibrated for Argon. But it can be used for other inert gases...but one would just need to adjust with a compensation factor (i.e. if using nitrogen instead of argon, it might need to be a higher flow shown on the meter, bc gases behave differently from each other based on density etc. There are factors posted online, I can't recall what it is when going from argon to nitrogen)

Both singe and two stage regulators will work. But I'd say a two stage would give better adjustment and more constant delivery.
There are better explanations of the these types than I can give.

The regulators that the PPH 2023 shows (page 134) is a 'Click Style Regulator'. There are used for home brewing etc.
Im not aware if these are singe or double stage type.
One may be able to attain these at a brewing supply.

What might be the recommended flow rate, I wonder?

 

[devils~advocate]

For Nitrogen, I think the official book mentioned at least 15 Liters per minute (L/m)
Some here have suggested that around 20-30 L/m is good for a variety of reasons (i.e. breathability, etc)

Most of the flow meters are not set up for Nitrogen though. Usually they are set up for Argon, CO2
Since Nitrogen weighs differently from those, a correction factor must be used if Nitrogen is used in one of those.

For instance from the chart below, if a flow meter or gauge is calibrated for Argon, then the correction factor for Nitrogen is 1.19.
To get 20 to 30 L/m for Nitrogen, the gauge would need to read a different number... 17 to 25 l/m
20 to 30 l/m nitrogen = 1.19 x 17 to 25 l/m argon

Thanks! A very useful resource.

Thanks also to the thread originator. This is useful stuff.

 

[fussyohno]

Great thread.

 

[devils~advocate]

Glad to help. Engaging in dialogue is sort of therapy for me in a way.
It helps me confirm to myself what I need to do in my circumstance.
Ask any questions...any information is useful.

Have you found anywhere that will sell you 99% nitrogen yet? I'm struggling tbh.

Yes check Adam gases uk on eBay

 

[apple2024]

the only reason o% nitrogen from Adams is in 75 litre bottles which weigh 76kg. Not sure I could manage to move that myself.
The smaller oxygen free ones are usually 10-20% CO2 which I've read will make you feel like you're suffocating.

What about this https://www.ebay.co.uk/itm/19527787...6&customid=1Kyw9qQfAAAAPtEusLME31LrBR4mAAAAAA

 

[apple2024]

Yeah I spoke to the local Adam supplier. That is the oxygen free nitrogen which has high proportion of CO2. The 99% nitrogen bottle from Adams starts at 75l

Can you send me a link in pm to the 75l because I can't seem to find it on the eBay site for Adam gas uk

Is 75l even enough. I'm seeing lots online about needing at least 500l and then I don't get all this or how to secure such amount of nitrogen or even helium and then it all confuses me with what regulators are needed for the specific tank. And all pure nitrogen is on sites like BOC etc and I am not sure if I will even be allowed to get them delivered. And if I was to pick up would I be asked questions and also if I managed to get it they will want to know how I plan to transport and I only have a car. Plus how much do these tanks weigh? I'm so confused and disheartened on how difficult this is. I am UK based by the way
