No, this is wrong. Taprite makes many regulators, almost all of the gauges show the flow rate in red. Don't believe this, just email or call the company, or call any brewing supply or welding supply store, you don't have to give your name or why you're asking the question, JUST ASK THEM! Over and out on this with you.
A regulator for compressed inert gases does not care what gas it's using. All inert gas cylinders share the same fitting. All inert gases will do the trick for what we're talking about here.
Yes, but for the folks in the US a nice proper flow rate regulator that is not as expensive as Maxx Dog or a oxygen regulator + adapter would be nice. They are sold all over the place here in Europe. Will google when i find the time.
This is so incorrect that I'm going to go back on what I said and try one more time, though as a retired teacher and longtime welder I recognize someone who knows they're right, no matter what the facts say:
Don't obsess over the flow rate! I can't say this enough: just about any rate will do. Hopefully you've read the first page or two of this thread that tells you everything you need to know, or any of the many other sources available for info about this simple and foolproof method.
Take the regulator into the store. You want something called a hose barb adapter, will look something like this:
On a medical oxygen regulator (including Maxx Dog) or one like the Harbor Freight that works via a constrictor (showing the flow rate in liters per minute or cubic feet per minute/hour on a round gauge that looks like the second gauge that shows the tank pressure) you dont have to worry about conversion factors. There is no difference in flow rate between argon, helium and nitrogen with such devices.
Yes, thank you. Many people used this method successfully in the early days when the recipe was "open the valve on the balloon tank a bit until gas flows out". A decent sized exit bag filled with inert gas will probably do you in even without any ensuing gas flow.

"Floating ball" type flow meters
show different rates for different gases. Here the difference in the density of the gases leads to difference in buoyancy of the ball. The type of gas the meter is calibrated for is indicated on the scale.

That today everybody obsesses about flow rate is due to the Australian group (now Exit International) and Nitschke's "Peaceful Pill Handbook". Probably confronted with people asking for less ambigous instructions they came up with using two balloon tanks and then a flow control nozzle they developed.
With the switch to nitrogen and higher pressure, industrial cylinders due to the diluted balloon helium regulators must be used. When a regulator is needed to reduce the tank pressure why not get one that also allows setting a flow rate? Industrial gas cylinders offer higher capacity than balloon tanks and gas flow over a longer time. While not strictly needed (any gas flow over, say, 15 minutes is basically useless) it offers a safety margin and room for errors.
A continous gas flow helps
-the bag to stay inflated
-ensures that no air leaks in over time
-flushes out the fraction of air that is still in the bag when pulled down
-flushes out CO2, which is problematic with smaller bags and if loss of consciousness takes longer (large air fraction in the bag when pulled down)
-peace of mind, room for errors
The 15 liters per minute that the PPH recommends is not set in stone. Its a ballpark number with as bit of safety margin.
PPH is to blame for over-emphasizing the importance of CO2 flushing. With a bag of a volume of 3 gallons / 15 liters and no gas flow it takes many minutes until CO2 concentration becomes a problem. At that time one is already deeply unconscious. (And breathing already stopped or about to stop)

My answer was directed to Sparks so there's no need to thank me! :-)On a medical oxygen regulator (including Maxx Dog) or one like the Harbor Freight that works via a constrictor (showing the flow rate in liters per minute or cubic feet per minute/hour on a round gauge that looks like the second gauge that shows the tank pressure) you dont have to worry about conversion factors.

You needed just one fitting, not fittings: a hose barb. Did you take the regulator into the store with you as I suggested?
Yes, and the hose barb threading doesn't match the regulator's threads. Neither did any other fittings.
My regulator is home and I'm out-of-state or else I'd look at it and tell you the correct hose barb size.
