Why can’t I find the right flow meter for nitrogen? Please help.

[thisandthat]

I know that you can use an argon flow meter but I can't find information on 15lpm nitrogen to argon conversion

Can I use a nitrogen flow meter on 32 scfh ?

That still seems wrong honestly

32 scfh is 15 lpm. Nitrogen flowmeters allow flow greater than 15 lpm. So yes. Is that your question?

Yes that answered that. what about cfh on an argon flow meter for nitrogen ? Like the one in the picture

I still can't find it I'm sorry. Is there any way you can answer it here ?

You don't see 2 overlapping dialogue "bubbles" at the top right-ish header portion of the page?

The pic you posted is an acu-200 argon/co2 regulator/flowmeter combo. Is that what you have and are going to use? You'll have to use conversion factor since calibtated for that gas mixture. I'm old school. I prefer the floating ball flowmeters. Honestly, don't think you even need good ones. It's just for trickling in some N2. If I were planning on inert gas, I'd just buy a Sparc setup, a regulator and a floating ball flowmeter. But, that's just me.

Which flowmeter would you use for nitrogen and on what setting ?

 

[locked*n*loaded]

Do you have a regulator already? Are you US?

I'm in the U.S. and no I don't have one yet. Also what size cylinder and how many liters ?

I'd just buy this cheap-ass regulator and flowmeter linked below, myself. The reg is for cga580 US tanks, though.

What you've shown in your picture previously should work just fine. Just need to do simple conversion factor.

At least a 40 cuft. You need a little extra to mess around with. 60 or 80 is better. Remember you've got to haul it home. Going up in size really doesn't cost much more.

Since you plan on using hood and not mask, getting that right would be my focus. Elastic has to be "snug" around neck, but not "too snug". The pressure in the hood (from the N2) needs to push out the CO2 you exhale.

thanks So much for your help. What scfh or psi would you use on those flowmeters you sent me?

Well, they're for nitrogen, so the flow should be 15 LPM. It should not blow up the bag like a balloon. The 15 LPM should be enough pressure to make a nitrogen environment inside the bag while providing enough pressure to push the CO2 past the properly fitted tension of the elastic around your neck. You will probably have to switch out the output fitting on the flowmeter with a barb style to attach a hose. And like I said, though, the flowmeter you showed me will certainly work by setting it to the correct conversion amount on the dial, which would probably 20-something LPM. Maybe 30. The BIG thing is to make sure they fill whatever size tank you get to FULL PRESSURE, which is like 2000 psi+.

Awesome bro thanks. So get both the flow meter and regulator ? Does the flowmeter have to be upright for the ball to read correctly ?

If I were doing inert gas for myself, that's what I'd buy. That cheap Chinese stuff would be worth the risk to me since only going to be using it once. If it didn't work, I'd just get another different one. Yeah, the ball-type, or float-type, both need to be vertical to work correctly. The click dial-type, like the one you showed, doesn't matter. The regulator doesn't matter, either.
