I remember loking at fuel canisters at the local REI.a few years ago. one brand had two markings on the out side. the idea was that the user floated the canister in still water and compaired the water level to the two markings. this would give the user a faily good indication of the remaining fuel.(along with the markings there were also instructions to accomplis this. I know that a person could make their own markings..but that would require that person to plan ahead and have both an empty and filled cans in order to figure out, where to place the markings. I always wished I had bought one canister of this brand so that I could just transfer the needed information to my already purchased canisters. now slowly gearing up for a section hike and would love to be able to read the current fuel level in any of my canisters
