You can not know if it is full without weighing the tank and subtracting its empty weight. The CO2 in the tank is mostly liquid with some gaz on top at 800psi (at room temperature). There must be some other gas mixed with the CO2 right now that contribute to the excess pressure and will be evacuated in a few days of use. The pressure will thus gradually drop to 800psi and not budge from there until all the liquid CO2 has been used up. When the pressure starts to drop below this level (about 800psi), then it is time to refill the tank.
