Do Propane Tank Gauges Get Stuck?

[ovrszd]

So propane is a liquid which would mean that on a warm afternoon (after a cooler night) you should be able to tell how full the tank is just by feeling the side. The level of the propane would be colder than the surrounding air and you should be able to feel that on the side of the tank.

Yep .

I just now had my 500 gal. L.P. tank filled. As you see gauge reads 75. Delivery guy fills until liquid comes out like in last picture I opened the valve like he does.
It's sunny, 40 deg.F.
