9kg Gas Bottle Gauge

One of the adhesive/magnetic ones you pour hot water over are very accurate and cheap. $3 or $4 from most camping shops.

Well, g'day Steve.

If your gas bottle is empty, you won't be able to do this, but then you won't need to either because the fridge will be warmed up, and you'll know.

1) Light the gas stove and boil half a litre of water.

2) Pour it over the side of the bottle.

3) Look at the bottle. It may have condensation up to the level of the gas. If not, you'll be able to feel the difference in temperature with your hand.

Important cautions:

1) Don't pour the hot water down your boots.

2) Don't burn your hand as you feel for the temperature difference.

Steve,

I have purchased a cheap set of fishing scales. Weigh the cylinder when full and when empty. Wright these figures on the bottle and you should have a fair idea of how much gas is left with a simple test.

Steve,

How old is your bottle?

A practical solution may be to buy a new Gas Bottle with a built-in gauge.
All you see is a small plastic gauge but the bottle includes an internal float mechanism to operate it.

I have these gauges on both the 9kg bottles I use at home and the 4.5kg bottle I take camping.

If your bottle is still worth the effort, you can have the float/gauge mechanism retro-fitted. You would need to check who is authorised to do this in your State. In SA it's Maxbuilt Trading Co.

I agree, its handy to be able to check at a glance how much gas is left in the bottle.

Or you could buy yourself a Gasfuse. It has a reasonably accurate gauge combined with an automatic cutoff if your line downstream is breached.

Hot water works for me takes about 5 seconds when poured onto bottle. Does not need to be boiling, if at home out of the hot tap is good enough
Cheers

Shake the bottle - it'll give you a reasonable indication of how full it is.
