I personally don't like the idea of a float as there is a mechanical element to the sensor that will rely on friction among the edge of the container or whatever your float is sliding against.
I don't understand what the problem is here. It will take some work to make a simple, cheap and reliable design, but what is so inherently bad about something floating up the side?
