Electromagnetic flowmeter application field:
1, industrial production process
Flow meter is one of the major types of process automation meters and devices, it is widely used in metallurgy, electric power, coal, chemical industry, petroleum, transportation, construction, textile, food, medicine, agriculture, environmental protection and People’s Daily life and other fields of the national economy, is to develop industrial and agricultural production, save energy, improve product quality, An important tool to improve economic efficiency and management level occupies an important position in the national economy. In process automation instruments and devices, flow meters have two main functions: as a test instrument for process automation control systems and a total meter for measuring material quantities.
2. Energy measurement
Energy is divided into primary energy (coal, crude oil, coal bed methane, liquefied petroleum gas and natural gas), secondary energy (electricity, coke, artificial gas, refined oil, liquefied petroleum gas, steam) and energy-carrying working medium (compressed air, oxygen, nitrogen, hydrogen, water). Energy measurement is an important means to manage energy scientifically, save energy and reduce consumption, and improve economic benefits. Flow meter is an important part of energy metering meters, water, artificial gas, natural gas, steam and oil these commonly used energy are using a very large number of flow meters, they are energy management and economic accounting tools.
3. Environmental protection engineering
The discharge of flue gas, waste liquid and sewage seriously pollutes the atmosphere and water resources, and seriously threatens the living environment of human beings. The state has listed sustainable development as a national policy, and environmental protection will be the biggest issue in the 21st century. To control air and water pollution, management must be strengthened, and the basis of management is the quantitative control of the amount of pollution, flowmeter in the flue gas emission, sewage, waste gas treatment flow measurement has an irreplaceable position. China is a coal-based country with millions of chimneys pumping smoke into the atmosphere. Flue gas emission control is an important item of * pollution, each chimney must be fitted with flue gas analysis meters and flow meters, consisting of a emissions monitoring system. The flow rate of flue gas is very difficult, its difficulty is that the chimney size is large and irregular shape, the gas composition is variable, the flow rate is large, dirty, dust, corrosion, high temperature, no straight pipe section.
4. Transportation
There are five ways: rail, road, air, water and pipeline transport. Although pipeline transportation has long existed, it is not widely used. With the prominent environmental problems, the characteristics of pipeline transportation have attracted people’s attention. Pipeline transportation must be equipped with flowmeters, which is the eye of control, distribution and scheduling, and is also the best tool for safety monitoring and economic accounting.
5. Biopharmaceuticals
The 21st century will usher in the century of life science, and the industry characterized by biotechnology will develop rapidly. There are many substances that need to be monitored and measured in biotechnology, such as blood, urine, etc. The pharmaceutical industry is also inconsistent or lacking in controlling flow meters for various pharmaceutical formulations and liquid preparation ingredients. The development of instruments is very difficult and there are many varieties.
6. Science experiments
The flowmeter required for scientific experiments is not only large in number, but also extremely complex in variety. According to statistics, a large part of more than 100 kinds of flow meters should be used for scientific research, they are not mass produced, sold in the market, many scientific research institutions and large enterprises have set up special groups to develop flowmeters.
7. Oceans, rivers and lakes
These areas are open flow channels, generally need to detect the flow rate, and then calculate the flow rate. The physical principle and fluid mechanics basis of the current meter and the flow meter are common, but the principle and structure of the instrument and the use of the premise are very different.
