Your solution to measuring the amount of CO2, in the bottle, is to use a 12V gas pressure transducer and to connect that to the regulator's gauge, which shows the bottles pressure, (not the supply side pressure). Then connect that to Robo-Tank. You will need the appropriate code to convert the voltage/data input to something understandable, but that is pretty straight forward.
This method is immune to any restarts and unlike a pressure plate/scale, does not need to be reset when you do a restart.
Something like this, would suit:
and simply add a t-piece between your regulator and the pressure gauge which displays the bottles pressure, like this:
Then when the bottles pressure starts to drop, you can have an alert set up to warn you. Be aware, depending on the rate at which your using CO2, that will only give you 2 to 5 days warning before empty. But at least you'll know. Also as it's data you can add code to display the current pressure on the Home screen.
