There are a few factors that can make the sender non-linear, the sending unit itself, odd shaped tank, and of course position. If it leans heavily in one state a bridge resistor circuit can level it out somewhat.
If the sender had a float arm (sounds like thats not the case here), you could also use "S" bends on the arm.
Of course there's always the tried and true "graduated broomstick" method.
