Malaysia Cement Plant-small Diameter Magnetic Flow Meter Application

Flow measurement used to be almost a blank in the cement industry, automation technicians often only know temperature, pressure, level and other metering sensors. With the increase in cement production scale, the process is constantly updated, flow measurement and new small diameter magnetic flow meter also began to be applied in the cement industry.

Magnetic flow meter can be applied to various links in the cement production process, such as raw material batching, making, firing and so on. In the raw material batching process, magnetic flowmeter can quickly and accurately measure the flow of various raw materials, so as to ensure the production of standardized mixture. In the cement making process, electromagnetic flowmeter can real-time monitoring of the mill in and out of the material flow, improve the operation efficiency of the mill, to ensure the production of high quality cement. In the firing process, magnetic flowmeter can measure the inlet and outlet flow of hot air furnace and rotary kiln to ensure the production of standard cement clinker.

This cement factory used traditional measuring equipment in the production process often appeared inaccurate measurement, maintenance costs and other problems, seriously affecting the production efficiency. After the manufacturer's technical team's research and debugging, they chose magnetic flow meter as an alternative program. After a few months of use, the customer feedback measurement results are accurate and stable, equipment maintenance costs have been significantly reduced, and production efficiency has been significantly improved.

Electromagnetic flowmeter is the application of the principle of electromagnetic induction, according to the conductive fluid through the applied magnetic field generated by the electric potential to measure the flow of conductive fluids, an instrument. Its characteristics are:

1. Measurements are unaffected by changes in fluid density, viscosity, temperature, pressure and conductivity;
2. No flow-obstructing parts in the measuring tube, no pressure loss, and low straight pipe section requirements. Unique adaptability to slurry measurement;
3. Reasonable choice of sensor lining and electrode materials, i.e. good corrosion and wear resistance;
4. The converter adopts novel excitation method with low power consumption, stable zero point and high accuracy. The flow range is up to 150:1;
5. The converter can be combined with the sensor in a single unit or in a separate unit.
