    We use 47 Kg Propane Calor Gas Cannisters just for our cooker hob as we aren't on mains gas here, but is there a simple dumb way to know when they are getting low?

    I know we just let them run out and when they are empty, they are empty! (simple I know)!!

    But just wondered if I was missing something obvious, as a guage to see how low or how much were still inside these?

    Its just the last few we had to guess, and they run out at the most annoying moments, like Xmas day or New Years Eve! (has happened)!

    Sorry for being stupid...! :)

    Weigh it?

    Has the cylinder got a tare weight stamped or printed on it anywhere?

    Or just buy a second one!

    A spare cylinder and a changeover valve would solve your problem.

    For some reason, the small 13kg patio gas cylinders come complete with a gauge.

    Not sure why someone bbq-ing should be more important than a domestic user .....

    @snes you are 100% right! Know one in their right made that loves a BBQ would use a bottle anyway! Give me a choice of charcoal, wood, smoking, tears in my eyes, the occasional flare up from fat, the odd burn here or two, the excuse to get another cold beer out to "soothe" the burns, the envy of the neighbours a street away who can smell you having one and the great neighbours that pop round because they could smell you having one. Can you tell I love a good cook out!?

    Back to the OP, the gauges you've been shown witll work if you're tight for space. A second bottle and changeover valve is the ideal solution as this will give you plenty of time to sort another out when one goes.

    Cheap bit not accurate solutions are, depending on the temperature outside, if you are running something full rate you may notice a line develop around the bottle as small ice particles form where the liquid lies. Another is to get a small spanner or similar and tap the bottle from top to bottom. Their should be a slight to distinguished change of note.

    Best off with a secondary bottle and a changeover though as this is the best and safest option.

    OP, your solution is to have a 13 kg standby to use as an emergency for when the big one runs out.

    I have a brand new full 47 kg one which I don't need and must get round to selling. I bought it with a range cooker but now that's on mains gas.

    Somewhere I have the auto change over too but no idea where.
