How to tell when gas nearly empty?

[marc4242]

I assume it's done by weight. We're still on our first canister, for those with Rascal / Hijet type vehicles with the canister about mmm 10-12" high, what weight is it when full/empty?

I don't want to run out mid Glastonbury ... ;D

We always take a spare, so if one runs out then you've always got gas, then get a replacement when convenient.

It always manages to run out when we are cooking a meal, then again it wouldn't run out when we weren't using it would it.

I hope this post is appropriate, as perhaps you all know about this and this is telling you how to ' suck eggs' so to speak... apologies if it is..

For me, gas always runs out at an inconvenient moment so have solution with my trailer tent. I have a two way gasglow valve, both cylinders are connected. When one runs out all I do is switch to the other cylinder, seconds then I can change the empty cylinder at a convenient moment. You can get automatic ones but I thought they were dangerous as you might not pick up that the gas supply had switched to the other cylinder, manuel is fine for me.

Tare weight is stamped on bottom rim of Gaz cylinders, a 907 is abt 3.2 kg I think with 2.72kg of gas when full.

If I need a rough estimate I disconnect mine and give it a slight shake. Keeping your ear close and feeling how the weight and sound sloshes around you can get a pretty good guesstimate on how full it is.
