How might a potentiometer be used to give a remote reading of the level of liquid in a tank?

By mounting the potentiometer (pot) in a way that the control shaft can be connected at a right angle to an arm with a float on it, the varying resistance that would come with changing tank level could be monitored from a remote location. Just run a couple of wires from the pot to your remote position. One wire goes to the wiper and the other wire to one end of the pot. Picture how the float in a toilet tank works. Instead of a valve operated by the float, how about having it rotate the shaft of the pot? Should work pretty well.
