Camping Gas - when to refill

[WelshMoth]

Is there any way of telling when we need to refill the cylinders? I have no idea how many hours I have left in my cylinder.

You can generally feel when they are getting empty.

Or if you have bathroom scales you can weigh it and work out how much you have in it www.camping-gas.com/find-a-stockist/search-results/search-results-products.php?manufacturer=Campingaz
