That is an interesting concept using an O2 regulator on a CO2 cylinder, I
am not sure it will work and would not advise it. That said, a full
cylinder has a pressure around 800psi (say 700-950 depending on the
temperature and gauge calibration). The best way to tell how much CO2 is
left is weigh it and subtract the tare stamped on the shoulder of the tank.
