Can you tell how full a tank is by tapping on the side?

The simple way is to look at the E/F gauge on the top of the tank.

If the tank has one and it's a float guage. Pressure guages are just
about useless on a propane tank. But I'm thinking the op would have
mentioned a guage if there was one.

Otherwise you are trying to find the liquid level and tapping is about
as good as anything. You can vent a bunch of it if it's humid out and
look for a condensation line. But that's not really a very good thing
to do.


Check it on a warm humid morning after a cold night, works best if the
sun hits it.
