Electromagnetic flowmeters and other scientific instruments can best reflect instrumentation as an important tool for knowledge innovation and technological innovation. It is also one of the themes of scientific and technological innovation research and an important manifestation of innovation achievements. Innovation makes electromagnetic flowmeter products continuously improved. It is developing in the direction of high performance, high precision, high sensitivity, high stability, high reliability, high environmental protection and long life. A large amount of demand in various industries has promoted the innovative development of electromagnetic flowmeters. Electromagnetic flow meters have a wide range of applications. Large-caliber instruments are mostly used in water supply and drainage projects, and medium- and small-caliber diameters are often used for solids, liquids, and difficult-to-measure fluids or high-demand locations. For example, pulp and black liquor in paper industry, pulp in non-ferrous metallurgical industry, coal slurry in coal preparation plants, The strong corrosive liquids in the chemical industry, as well as the control and monitoring of the cooling water in blast furnace tuyere outlets in the iron and steel industry, and the flow measurement and control of long-distance pipeline coal hydraulic transmission. Small calibers and micro calibers are often used in places where there are health requirements, such as the pharmaceutical industry, food industry, and bioengineering. Electromagnetic flowmeters were developed in the middle of the 20th century. They are used to measure flow measurements in various media and have their own unique application fields. Previous types of electromagnetic flowmeters were single, but with the development of technology, the types of electromagnetic flowmeters have become more More and more, more and more caliber, flow meter selection presents a single instrument to the development of diversified instrumentation, high pressure, high flow line ultrasonic flowmeter and other new flowmeters will be widely used. Electromagnetic flow meters play a very important role in people's industrial production. With the development of technology, the types and characteristics of electromagnetic flow meters are continuously changing to meet the needs of the market, but from the current market, Electromagnetic flow meters are constantly moving forward, and innovation plays an important role.
