Aug 10, 2008. #2. I worked in mining for a lot of years, most of the thickeners had a float device. A SS ball about 6" diameter sliding on a length of SS tube. A magnet inside the float activated a series of reed switches inside the tube. I think it was in about 5% steps. The ball is filled with sand or water until it just sinks in water ...

There is a level-sensing probe located on the thickener to monitor the bed, or sludge, level in the thickener. Typically, the level-sensing probe is weighted so that it sinks in the clarified water and floats on top of the solids in the bed. Just as the bed level rises and falls, so does the sensor inside the probe. This level measurement is ...
