Using Argon regulator for Nitrogen (inert gas method)

[Notaname]

I bought an argon flowmeter, but I'm using nitrogen. I know there's a density difference in the gases, and saw people saying I'd need to set it higher to get the proper l/min with nitrogen. Shouldn't I need to set the argon meter lower since nitrogen is less dense and will interact less with the ball? It's a matter of ~21 l/min or 13 l/min on the argon. I just don't want to set it too high and waste all of my nitrogen brain damaging me.

No I didn't do it.

I'm looking for the same answer so I ran a test nusing half a tank of Nitrogen which initially contained 2 litres of gas at 200 bar

Given that the tank had initially contained 400 Liters of Nitrogen gas and was now at a reading of 100 Bar i am assuming that I had 200 Liters of gas remaining.

After setting the regulator to 10 LPM it took 6 mins for the regulator to reach the tank 50 Bar mark at which point the flow meter had gone from 10 LPM to 11 LMP so i readjusted the flow meter to give a reading of 10 LPM and the gas flowed for another 6 mins before the flow rate began to slow down.

This would mean that using a 10 LPM / 11 LPM reading. That 200 Liters of Nitrogen took 12 minutes to deplete.
This would mean that the true flow rate was actually 16 LPM and not 10 LPM.
