Empty the small bottle and close the valve. Weight it to the ounce and make note. Put it in a freezer for awhile. Hours if you have the time.

Pull it out, hook it up, open both valves, give it a few shakes, close the valves after 20 seconds or so. Weight it again. It will likely be overfull. Bleed gas off until it weighs just 10oz more than when you started or less

Do NOT leave it overfill. It will over pressurize when it warms up and bad things will happen. At a minimum it will pop the safety disc and scare the s### out of you.

Equipment is nothing more than a couple of bottle nipples with 6AN adapters and a length of Teflon AN hose with -6 ends.
