Ever wonder how much beer you have in that 5 gallon cornelius keg? Well, me too! Some people are satisfied with seeing the condensation line on the side of the keg. I would like to know the volume of the brew in gallons.
A solution I came up with for myself was to weigh an empty keg and another keg full. I then drew up a scale to fill in the rest. Now when I want to see how much brew is left I just pull out the bathroom scale (I gotta use it for something!), weigh the keg and look up the volume on the scale. Below is the scale I made. There maybe weight differences in some kegs, but it should be close enough for government work and you don't have to wait for condensation to form.
