Patented process for sludge level measurement

In contrast to the usual optical or acoustic techniques for measuring the sludge level in sedimentation tanks, the process developed by us uses passive pressure sensors to measure the difference in density between the sludge layer and the clear-water layer.

The sensors measure the upper sludge level in the separation zone between the clear water and the sludge running up to it, as well as the lower sludge level between the retention zone and the thickened sludge at the bottom or in the filter.

This easily applied, patented technique for measuring differences in density manages without any moving installations in the secondary sedimentation basin. The measurements are particularly reliable as the more or less maintenance-free sensors are insensitive to soiling.
