Given a cylinder of a constant shape and size, how can the water level be calculated using the inside surface of the container?

For instance, could the inside lining of the container be a pressure sensitive foil of some sort, and using that pressure could the water level be calculated?

Pressure will be hydrostatic, so $\rho g h$ with $h$ measured down from the surface of the water. Put a pressure sensor at the bottom of your container, and you can calculate the water level from that, yes. – Jaime Nov 27 '12 at 0:09
