I take it that pump is "submersible", totally under the water in
normal operation?

Couldn't you simply measure output pressure?

Around here we periodically drain our swimming pools (to get rid of
mineral concentration due to evaporation). A submersible pump is
used, which turns off automatically when the pool is empty. Wonder
what they use?
