Help can a regulator flow meter on Amazon for exit bag work

[ocean2200reef]

Would a regulator flow meter work from Amazon there are a bunch that show up. I plan on buying an argon one and using it with nitrogen tank I have already calculated it to scfh

You're going to use argon? Then yeah, why wouldn't an argon regulator/flowmeter work? Amazon sells the same equipment, for the most part, as anyone else. If you're going to use nitrogen, get a setup for that. Make sure to match the type of connection to whatever tank you buy.

Argon regulator/flowmeter will work fine for Argon / Helium / Nitrogen gases.. They all use the same threaded connection to the cylinder....cga-580

There are nitrogen regulators that have a flowmeter but they are expensive.

Like you mentioned, just have to take into account the flowmeter conversion for Nitrogen.
I think when using Nitrogen in an Argon flowmeter, the conversion is 1.19...so not much difference.



Most of the flowmeters in the USA are show in units of SCFH standard cubic feet per hour
15-20 liters per minute = 32-42 scfh

So using an Argon flowmeter with Nitrogen gas, the conversion is 1.19.
Argon is heavier than Nitrogen. I thought more than what these conversion tables state, oh well.

So for 20 lpm or 42 scfh of Nitrogen......the Argon flowmeter would read: 42 scfh/1.19 = 35 scfh

----------
Sometimes the same flowmeter with have units on it for CO2
Same conversion for using Nitrogen......except conversion is 1.26 in this case.
42/1.26 = 33 scfh

I tried this regulator for nitrogen and tightened it and it leaks. What other ones are there that are similar to the one I have attached. Apparently I was advised the one that I have below, has a low flow. The connection valve is for a CGA580 cylinder.
