If you have a container and you put two vertical parallel wires in it,
why can't you determine the quantiy of a liquid poured into that
container based on the resistance measured between the two wires?


Basically too many variables. You would have to know the diameter &
lenght of the container, the diameter of the wires, the depth of
their immersion and the resistivity of the liquid.
Even then you could only determine any difference in the levels of
liquid. not the absolute amount unless the wires touched the bottom of
the container and assuming it was an insulator.
