Does the SuperFlow regulator gauge tell me how much CO2 I have left?
No. It will only give you a rough indication of when you are nearing the end of the CO2. The only way to get an accurate read on how much CO2 you have left is to weight your tank. What we recommend is that you weigh your Power TankTM assembly on an accurate scale while it is empty. Record this empty weight (write it down with a permanent marker on the tank weight box on the lower label). Once the tank is filled check to make sure you got an accurate fill (ie. a PT-10 should weigh exactly 10 lb. more than empty). Before you go on a job you will now be able to weigh your Power TankTM and get a good idea of how much CO2 is left in the tank. We offer a very accurate handheld digital Super Scale (P/N CO2-2050) so you can weigh your tank anywhere, anytime.
