Fairly new to camping so please be kind to me, but is there such a device that can tell how much gas is left in your bottle. Dont want to get caught out between trips or on site but have never seen anything for sale. Is there any sort of tester  / monitor device out there that could be connected to valve , if so any reccomendations would be appreciated.

Pour the contents of a boiling kettle down the side of your gas bottle.Then feel down the side  of the gas bottle from top to bottom. Where it goes from hot to cold that is the level of the liquid gas still in your bottle.Hope this helps.

Many sites sell gas and there's usually a supplier a short drive away if not. The only time I worry is if we're not on hook up & it's low in winter as it may run out in the middle of the night & we'd be cold in the morning without the gas fire. The fridge will be fine for a few hours while we get another bottle on.

I've got a magnetic temperature gauge that is supposed to show the level on my propane bottle.

We have a magnetic one, It dos'ent seem to tell us anything unless its us not understanding it but we always carry two bottles.

We have a surplus of blue gas bottles, does anyone who is going to meet at Eden want one ( empty of course) if so we'll bring them with us.

Hi

there is a weight on the metal tag at the top of the bottle, thats the weight when it is full, so if you weigh it and subtract the weight from the tag weight it gives you the weight of gas left.

cheers

I`ve got no scientific basis for this, but pouring boiling water over a metal bottle containing a flammable gas sounds a bit dangerous to me! What if the cylinder was very cold? You might crack it...or something....expand the bottle but not the valve ball so it leaked?

I`ll stick to my two cylinders and paranoia...

Thanks Tony & Steve.

I will give the hot water a go, if that doesnt work then will get the scales out. As space is tight for 2nd bottle then hopefully one of these will work.

Cheers

George Telford mentioned this once before Steve but my bottle doesn't have a metal tag.

Don't get paranoid Val  . I think it would be safe enough. All dealers keep the cylinders outside their premises - on a hot Summer's day the metal will get a lot warmer in direct sunshine than it will from having a kettle of boiling water poured over it. The idea is not to pour it directly onto the top of the bottle, but down the side, so it will not go near the valve.

I'll have another look at it when it's daylight George.

At the New Year meet at Bedfordshire we could tell Claire's propane bottle (running her patio heater) was running low because there was frost around the bottom of the bottle it was that cold in the barn.
