I’ve worked on/installed some that used capacitance to measure levels; the one used on the Hunters used to be the Snake River system. I think they might have been bought up by another company; no Google hits for them, but rather for these guys:
https://www.tankedge.com/ These systems are nice — self-stick a pair of conductive strips vertically on the outside of plastic or fiberglass tanks, and connect the terminal blocks; then wire to the panel. Unfortunately, they won’t work on metal tanks. But no internal parts to get gummed up in the holding tank.
