I'm reading this in s.e.b but yeah capacitance has always seemed a better way to sense levels to me, does it work well for non-conductive liquids like oil or gasoline? (conductive sensors can't work there) can it be used with compressed (non-liquid) gasses?

for plants they use ultrasonics to measure the distance to the waterlevel as the pumps are of a size that can't be directly switched by a floating switch.
or a sensor with hysterisis (those floats have it)

The hydrogen overvoltage of iron makes stainless steel largely useless for most electrolysis.

-- There are lots of different ways of sensing water level which don\'t involve contacting the water with electrically energized wires. Why can\'t you use one of those approaches?
i made a water level sensor once using a Ping-Pong ball inside a little tube that would push against a resistor plate. just sealed the wire, outer enclosure and it produced a roughly shaped analog value.. never had any problems with it.
