Your LPG storage tank should have a gauge that shows you how much fuel it has in it. Most LPG suppliers suggest that you arrange a fuel delivery when the level in your tank gets down to about 20%. Make regular checks, particularly in the winter when you will use more, so you know when levels are low.
