It\u2019s pretty low, but I\u2019m still holding pressure.\u00a0 If you want to know how much is left in the tank that is more accurate than your gauge, first look for the TW on the tank.\u00a0 TW stands for <em>tare weight<\/em>, and it tells you what the weight of the cylinder is.\u00a0 Mine happens to be 25.0 lbs.\u00a0 So now all I have to do it put my tank on a scale and see what it weighs.\u00a0 Then, subtract 25.0 from that number, and that is how much is left in the tank.<\/p>\n<p>00:50 I used an old giant household scale because it was all I had, however if you have something digital and smaller I suggest using that for a more exact reading. A little under 27.5 lbs is what my tank ends up weighing.\u00a0 So I take 27.5 lbs and subtract 25.0 lbs from it and I\u2019m left with about 2.5lbs in my tank.<\/p>\n<p>1:19 Another thing to note is that this is a 20lbs cylinder, so next time I exchange or fill my tank, the first thing I\u2019m going to do is weigh it and mark that value down to see if I always get 20lbs or not.<\/p>\n<p>At least I now know I have enough CO2 to get my next beer kegged and clear the head space.\u00a0 That will give me enough time to fill the tank before serving.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How do you know how much CO2 is left in your tank?\u00a0 I&#8217;ve been pushing my luck on how much is left in mine, and I want to know how many more brews I can force carb and serve before I need to fill it up or trade it in.
