The problem is that your sensor will corrode after a few weeks because of electrolysis. To avoid that, you should measure the resistance only for a very short time e.g. 10 ms and in intervals of maybe 10 minutes or something. For that, you have to switch the power pin of your sensor with a digital pin and a transistor or mosfet on and off. However, the sensor will still dissolve after a few months. Depending on the mineral content of the water, the resistance and thus your water level will also change.

Thanks Mr. Dollinger, for sharing your experience on this. I think, this sensor seems good if and only if we are approaching for developing a prototype to manifest our "Proof of Concept" for a bigger thing. The real time sensors for water level detection and measurement would be far more costly and sophisticated than this. Still I do appreciate the way you tried to enlighten me and the community with your precious comment.
