First, we turn on the stove and heat water, for example. The idea is that the cylinder is in use to do the test.
Then we fill a bucket with a little water and wet the whole tank.
We immediately let about 10 minutes pass and we will be able to observe how the tank shows a strip that dries faster. Well, that strip is a clear indication of the level of gas we have in the tank.
A very simple but highly effective method that we can apply at the first opportunity we have!
