OK I've taken my 10# bottle to two places so far to get it filled and both of them messed it up.
First one seemed to know what he was doing but the tank was low so I only got a partial fill. He actually weighed before and after and only charged me partial.
The keg place I went to today just totally amazed me though. Long story short I went three freaking times and I only have about 2# - 2.5# over tare.
Now the part I want to clarify that I'm sure I already know. I've been wrong before though so might as well make sure...
CO2 is measured in weight... not PSI, not some other funky unit. Simple weight. The bottle is at its tare weight (stamped on the bottle as TW) when it is empty and at tare weight plus bottle capacity when it is full. IE A 10# with a tare weight of 13.8 would be full at, or around, 23.8.
Second question would be, assuming all the above is right... I know the pressure can vary by temperature but does that affect the weight?
Either way though you take an empty bottle to someone and they fill it and it should be as much heavier as the capacity of the bottle right?
OK that rambled but I just spent a frustrating day dealing with a keg store that though they have an awesome selection of beers has no clue about CO2, lol. The kicker was the third trip there was at 8pm and they are located a couple blocks from a college... you do the math. Oh and I hit a sobriety check point on the way home... not a big deal as I hadn't had anything yet tonight but it did mean close to 30 minutes sitting in cop generated traffic.
