This sounds like it will not work but it does!
Monitor your pump runtime from a full tank to an empty tank.

What it actually sounds like to me is a really bad idea, because a
simple screwup can leave you thinking you have water in your tank that
you don't really have, the consequences of which could range from
unpleasant to life threatening. A flow meter has the same problem.
A real water gauge should always be used.
