An update on the OFCOM situation: As you know, censorship around the world has been ramping up at an alarming pace. OFCOM, the UK’s communications regulator, has singled out our community, demanding compliance with their Online Safety Act despite our minimal UK presence. This is a blatant overreach, and they have been sending letters pressuring us to comply with their censorship agenda.
Our platform is already blocked by many UK ISPs, yet they continue their attempts to stifle free speech. Standing up to this kind of regulatory overreach requires lots of resources to maintain our infrastructure and fight back against these unjust demands. If you value our community and want to support us during this time, we would greatly appreciate any and all donations.
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.
You can use an argon regulator (with flowmeter) on a nitrogen cylinder if the cylinder connection for nitrogen in your region is the same as an argon cylinder connection. ... You seem like you've done a lot of research. Do you know if a US (CGA580 flowmeter connection [like this one]) works...

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.
