Simple... keep a calendar, and after about two and a half weeks of use, refill.

Seriously, this subject has been picked over a lot and if our tanks
were mounted vertically, we might be able to use something like the
indicators that apply to the side of the removable metal jugs. Being
horizontal, they won't work. I think the $$$ gowesty replacement tank
has a gauge in it, some kind of a float. If they can install one that
means you can, too, if you have somebody to do the fab work if
required. I don't know of anyone who has actually done it, though.
