The newer Weber Genesis models have a spring-scale hanger
for the tank, but it's useless. Mine registered "empty"
about ten fires ago.

The liquid-crystal thermometer things they paste to the
sides don't work either. At least not when the ambient
temperature is 95 or above...

I've been thinking of that. I'll probably do it when
I change out The Eternal Flame, here. I want to weigh
this tank empty first, just to see how close to full
the trade-a-tank people are filling them. The rules
are you can't fill them more than 80% full, to allow the
float-valve to work. (The float shuts the outlet if the tank
is tipped, so the fluid won't be ejected; if the tank is
too full, the float always thinks it's tipped; the question
is how far below the 80% level the vendors are cheating).

Someone invented a fiberglass propane tank. It's not clear,
but it is translucent, and you can see the fluid level with
a little backlighting and sloshing. They'll sell like mad
if they're ever approved.
