Not really directly to a point, but we have a system around our house that helps figuring out which tanks are full and which are empty.
we live 100 miles from the nearest fill station, we do night dives at sites after the fill stations there are shut down or at sites that don't have fills to start with, so we always have some empties and some partials sitting around).
We have those little valve caps on every tank, and the rule of thumb is once that a reg gets hooked up to that tank, the cap stays off. That way we know it is not completely full. The only tanks that have the caps on them are full.
Doesn't relieve a person from doing their pressure checks, of course... also, some 'full tanks' are more full than others... an AL80 may be at 3300 "full" or at "2700" full since most places around here use hot fills and don't top em off so short fills are common. Some places will fill my LP's to 2640 (they are plusses) and some only 2400.
Again, this is besides the point since one needs to check every single time, absolutely.
Just sayin.
