Applications within the phosphate mining industry, specifically phosphate processing plants such as sulfuric acid and phosphoric acid lines, are highly corrosive and can be problematic for instrumentation that come in contact with these fluids. CiDRA’s SONARtrac® flow meter is a clamp-on solution designed specifically designed for flow measurement dealing with abrasive slurries and corrosive fluids like those in phosphate mining. The SONARtrac system never comes in contact with the fluid and it is a passive device so it requires no maintenance or re-calibration. The unique capability of the SONARtrac system to measure real-time entrained air can impact process improvements in slurry management, reagent addition and flotation optimization.
