Here are some references for capacitive proximity sensors (may be you can find something useful there):

When you say "level" do you mean level=horizontal
or the level of liquid in the tank?

dear kender,
with thanks for your attention i must say that these links are about overall description of capacitive proximity switches not about capacitive level meter. for capacitive level meter i mean a sensor and conditioner for measuring continious level of materials such as powderes or liquides in a tank by means of the capacitive changes of probe as a result of material level changes.
