Unless you just bought one of the new style marker mounted CO2 bottles that cannot be over filled you need to hang the bottle on the scale WHILE you are filling it. Hope you got a digital scale. Hang the scale at a height so that the neck of the tank is level with the fill station hose. Hang the tank with the fill hose attached from the scale hook and "zero" the scale. Fill the bottle until it reads the correct weight for the size bottle. A 20 oz bottle should stop being filled at 1 lb 4 oz.

If you intend to do a fill on a partially used bottle on occasion you should mark the total weight of the bottle, when full, on it some place. (weights vary slightly from manufacturer to manufacturer) Then you can just "top off" to total full weight as the need arises.

BTW, it is possible to put more liquid CO2 in the cylinder than it calls for. It won't blow up, but as the bottle warms in the car from the heater or from the sun , even in the winter, the rupture disk may blow leaving you without the gas you need to play and a bottle that cannot be refilled until the disk is replaced.
