Tanks & how much air is left
Ok..I have 2, 20oz CO2 tanks. I filled one up, but the other one felt still fairly full so i didn't fill it. I know you can get gages for the tanks that show how much psi is left, but i don't have that right now, im wondering if their is another way to tell how much is left.
I have tried to weigh them, but i didn't weigh the one when it was empty. I weighed them both and they are both the same weight. So either im doing something wrong, the guys who filled it didn't fill it all the way, or something else.
Does anyone know ho much a standard 20oz weigh empty?
