The Role of Measurement Instrumentation in Cooling Water Circuit in Mining Applications
Optimizing cooling water processes in mining applications
Maintaining operating temperature of cooling water in mining
Some steps of mineral processing in mining generate a tremendous amount of heat, which needs to be dissipated to maintain safe and efficient operation of equipment. Accurate measurement instrumentation of cooling water ensures that the cooling system is operating optimally, preventing potential damage to equipment and safety incidents. The Cooling Water Circuit is responsible for removing heat from process fluids, such as oil and acid pipes, by using cooling water that has a significantly lower temperature. It is important to monitor the temperature and flow rate of both the process fluid and cooling water to ensure that the heat transfer process is optimized. Without reliable instrumentation, it would be difficult to maintain a consistent operating temperature and ensure a safe and efficient mining operation. Emerson's measurement instrumentation solutions helps to maintain production output, prevent equipment failure and reduce costs.

The Flexim PIOX S721 ultrasonic density meter determines the concentration and density by means of clamp-on ultrasonic transducers mounted on the outside of the pipe. The non-intrusive technology found in this inline density meter is the system of choice when substances and processes place highest demands on safety and reliability. The sound velocity sensor PIOX S measures in real time the speed of sound through liquids. In binary liquids such as acids or sodas, the acoustic velocity is in a fixed proportion to concentration and density. PIOX S measures the sound velocity, thereby measuring the inline density and concentration of the medium.
- For all pipe materials - glass, steel, plastic and more
- For almost all acids, caustics and a wide range of other toxic liquids
- For ATEX, IECEX and FM areas
