Application of electromagnetic flowmeter in environmental protection industry

As the national requirements for environmental protection are becoming more and more strict, for the paper industry, sewage treatment has been an important indicator for assessing enterprises. In sewage treatment, sewage flowmeter is an instrument used by enterprises, among which electromagnetic flowmeter accounts for the largest proportion in the process of sewage treatment.

Why is electromagnetic flowmeter reused in sewage treatment of paper industry? First of all, of course, it has the characteristics of high precision, wide range, sensitive response and stable performance. In some cases, the electromagnetic flowmeter can be measured in both directions, and is not affected by the temperature, viscosity and density of the measured medium. There is no choke and no pressure loss.

The environmental protection industry has higher and higher requirements for the accuracy and reliability of sewage flow measurement and control. F. C. King horn, a foreign flow expert, once said that flowmeter is one of the few instruments that are more difficult to use than to manufacture. This paper describes the application of electromagnetic flowmeter in petrochemical wastewater measurement and the treatment of common faults.

According to the characteristics of sewage such as large flow change, impurities, low corrosivity and certain conductivity, electromagnetic flowmeter is a good choice to measure the flow of sewage. It has the advantages of compact structure, small volume, convenient installation, operation and maintenance. For example, the measurement system adopts intelligent design, the overall seal is strengthened, and can work normally in a harsh environment. The electromagnetic flowmeter with neoprene lining and Molybdenum Stainless Steel (ocri8ni12mo2ti) electrode can meet the requirements of sewage flow measurement.

For example, a smelter will produce a large amount of industrial sewage due to the needs of production process, and the sewage treatment plant must monitor the flow of sewage. In view of this situation, vortex flowmeter and orifice flowmeter are generally selected. However, in practical application, the deviation between the measured flow display value and the actual flow will be large, while the deviation will be reduced after using the electromagnetic flowmeter produced by Ruineng instrument.
