Water will exert pressure in a very repeatable fashion. But it is pressure per area. The larger surface of the scale means you need to calculate the area of the scale to find grams per cm2. From there you can calculate depth very accurately. I work in industry and we do this for a variety of reasons, the most obvious is to measure the height of liquid in a tank.
