We have gas in our new place, one big bottle. 40Kg or so, I'd say.
Problem is there is only one bottle as the gap between the bottle and whatever else (door, window) doesnt allow for two bottles, so when it runs out we have a two day outage. Is there a level meter that can attach to the outside of the bottle temporarily? I think I've seen this before as it measures based on temp of the gas/no gas?
Or any other suggestions?
