Accurate and efficient slurry level and froth thickness measurement in flotation cells improves level control and helps prevent cell overflows and draining issues, both common problems with existing technology. Outotec LevelSense is a reliable, robust solution designed specifically for Outotec flotation cells to replace traditional ball-float measurement systems. It contains no moving parts, meaning it is extremely reliable and easy to maintain.
Outotec LevelSense™ monitors slurry-froth and froth-air interfaces in flotation cells, providing a highly accurate and repeatable measurement of froth-bed thickness. It uses electrical impedance tomography (EIT) technology to accurately analyze and measure the media inside process tanks and pipes. Measurements are based on the conductivity distribution of the media and advanced mathematical modeling.
Accurate froth-bed thickness measurement allows better control over the metallurgical performance of the cell. Outotec LevelSense can also monitor collapses in froth level and overflow, which improves both the stability and economic performance of the flotation process. LevelSense can be expanded with powerful tomographic analysis of froth and slurry characteristics as well as Outotec Advanced Control Tools for optimizing flotation cell performance.
