The problem, IIRC, with the temperature method is that it only works

you've fired off enough gas to cause a temperature drop in the tank. *I

The liquid level shows up almost immediately.

Unfortunately, pouring water on an icy porch (or worse, inside the house!)
counts as "excess horsing around." *While I am sure it's great for barbecue
gas tank testing in mid-summer, it's not going to be a helpful method in
this case - melting ice on the front steps. *I'm still convinced the
embedded scale is the perfect solution here.

I was on your side for a while, but I gotta disagree with you
here. ;-)

If you've got the device out on the icy porch, it's because you are
about to use it right?

A small additional amount of water in an area that you are about to
torch - and I assume dry up - won't make any difference.

In fact, it will melt the ice before you even put the torch to it,
thereby saving propane. Do the math. ;-)
