Co2 Meter
Basically this would be the same as a propane meter for a combustion. Just 2 ball valves, a pressure gauge, a street elbow going into your chamber, and a piece of pipe. Calculate the volumes and how much pressure would it take to pressurize your chamber to 90 or 100 psi, put dry ice in one ball valve, close it, wait for the pressure you want in the meter, and open the other ball valve. Portability!

Actually, you might have a little something here.
If you've got a CO<sub>2</sub> tank and adapter, (not regulator), you could fill some 1/4" or 3/8" steel pipe to a full 800 PSI, (first make sure it's rated
), and use the P1(V1) = P2(V2) equation to see what length of pipe you'd need to get the chamber to 100 PSI.
Cheaper than a CO<sub>2</sub> paintball regulator, in any case.

...or just use that and save yourself a hell of a lot of time and some money...
Whats the dry ice for... how are you getting dry ice and holding it on the ball valve... and how is this practical for portability...

What we are describing is basically a propane meter with CO<sub>2</sub>.
Even using propane, the pressure in the chamber raises slightly when you inject propane, (with a good sealing projectile).
Basically, you're just switching the propane to CO<sub>2</sub> and taking the pressure WAY up to fill the chamber to 100 PSI from an 800 PSI tank without a regulator.
