Intelligent electromagnetic flowmeter is a kind of precision measuring instrument, which is widely used in many industries such as industry, chemical industry, electric power, electronics, machine tools, shipbuilding, metallurgy, petroleum, medical, etc. With continuous development , the technology of intelligent electromagnetic flowmeters has been improved and the fields of application have become more and more extensive.
Flowmeter is widely used in industrial and agricultural production, national defense construction, scientific research, foreign trade and daily life. With the development of industrial production to the direction of automation and the needs of people’s daily life development, flow meters are used in the entire instrument production. The proportion is increasing, and data shows that the flow meters used in different industrial sectors account for 15 30% of the total number of meters. The technology has been greatly developed, and the flow sensor tends to be electronic, digital, and multi-functional, opening up new fields for flow measurement. The new flowmeter has the characteristics of wide range ratio, intelligence, high reliability, low price and convenient maintenance.
