It could, but would be just as worthless as it is on a standard propane
tank. Propane changes from a liquid to gas as it is used. That gauge
measures pressure. Until the propane is almost all the way gone (no
liquid left), the pressure is directly related to temperature, and has
almost nothing to do with how much liquid is left in the tank. A gauge
which says everything is fine until you're 10 minutes from empty is
pretty worthless, IMHO.
