Victor Flow Meter arived today. its got setting for Argon, CO2, Helium. theres no N2 flow setting. is there a conversion i can use?
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 was actually surprised at the big difference myself.Sorry to pry, just wondering.
That doesn't make sense as helium is so much lighter than argon. How could the flow rate be the same for helium and argon? I'm wondering about how accurate this dartmouth page is.I was actually surprised at the big difference myself.
And I too, wondered about @TiredHorse
The flow rates between helium and argon are almost identical, but BIG difference between them and nitrogen.
Nop, seems it is specific to the flowmeter.should we use
WHEW! That's a much greater difference than I would have expected! I think I set the flow a bit higher, just to err on the side of caution, but not as high as 22 LPM. Maybe 17 or 18?Do you think that may have had a role in your failures Tired Horse, or did you set the flow a bit higher to compensate? Sorry to pry, just wondering.
I think that is a wise choice, considering the ambiguity of it all.N2 flow meters are hard to come by with the 580 connection. i'm sending my Victor back and going to get this Harris 335-2N2
thanks Color Me GoneI think that is a wise choice, considering the ambiguity of it all.
Nothing better than buying something that absolutely fits the application,
especially considering the criticality of this application.
I know it's a lot of cash to keep tied up, but it might be interesting to keep the Victor for the moment, order the Harris, and when it arrives hook the Victor and the Harris in line and see how they differ.N2 flow meters are hard to come by with the 580 connection. i'm sending my Victor back and going to get this Harris 335-2N2
You're very kind. I haven't decided even if I'm heading back to the bus stop, let alone what method I'll use once I get there. I'm very uncertain, very tired, very unhappy; recovery is an uphill slog, at best. Each method has a lot going for it, and I suspect which I use will be a matter to decide on when the moment is upon me --but I will bear your words in mind.TiredHorse... please use the N2 method. guns are too violent and i hope you do it peacefully which you deserve for all the help you give.
A gun does have its advantages.stop waffling and use a gun
Additionally, I did get greying out around the edges of my vision, which implies to me that I was on the edge of blacking out. The N2 was taking effect, but not fast enough to outpace my survival instinct. I suspect my delayed onset of unconsciousness was much more a factor of my very shallow stress-breathing than of inadequate gas flow.
Nop, seems it is specific to the flowmeter.
If you look at the physicsforums link I provided, a guy was questioning the fact that 4 different companies gave four different sets of conversion factors, which, in some cases, varied widely between them.
So it remains a mystery.
I would NOT assume those values I gave to work for just any meter.
The answer would be, either buy a flow meter designed specifically for the gas you are using,
or use a conversion factor given specifically by the manufacturer of the flow meter you are using.
Sorry, it just sucks!
Purchasing N2.... my experience in buying the N2 was to read a quick article on winemaking and N2.... tell the clerks your learning the homemade wine process etc. it works really well. ask if they have any other wine making customers in casual conversation etc. these guys tell me they have some beer customers but no amateur wine makers. i was able to buy N2 from 2 different sources. i'll practice the art and when its time for the bus i'm going to try and get Beverage grade N2 if i can...
