1. Application areas of gas flow meters

Gas flow meters are widely used, and the application of flow measurement technology and instruments can be roughly divided into the following areas. 1、 Industrial production process flow meters are one of the major categories of instruments and devices in process automation. They are widely used in various fields of the national economy, such as metallurgy, power, coal, chemical, petroleum, transportation, construction, textiles, food, medicine, agriculture, environmental protection, and peoples daily lives. They are important tools for developing industrial and agricultural production, saving energy, improving product quality, enhancing economic efficiency and management level, and occupy an important position in the national economy. In process automation instruments and devices, flow meters have two main functions: as detection instruments for process automation control systems and as total quantity meters for measuring material quantities. 2、 Energy metering is divided into primary energy (coal, crude oil, coalbed methane, petroleum gas, and natural gas), secondary energy (electricity, coke, artificial gas, refined oil, liquefied petroleum gas, steam), and energy carrying working fluids (compressed air, oxygen, nitrogen, hydrogen, water). Energy metering is an important means of scientifically managing energy, achieving energy conservation and consumption reduction, and improving economic efficiency. Flow meters are an important component of energy metering instruments. Commonly used energy sources such as water, artificial gas, natural gas, steam, and oil all use an extremely large number of flow meters, which are indispensable tools for energy management and econom

ic accounting. 3、 The chain discharge of environmental protection engineering flue gas, waste liquid, sewage, etc. seriously pollutes the atmosphere and water resources, posing a serious threat to the human living environment. The country has made sustainable development a national policy, and environmental protection will be the biggest issue of the 21st century. To control air and water pollution, it is necessary to strengthen management, and the basis of management is quantitative control of pollution levels. China is a country that relies mainly on coal as its energy source, with millions of chimneys continuously emitting smoke into the atmosphere. Smoke emission control is an important project to eradicate pollution. Each chimney must be equipped with smoke analysis instruments and flow meters to form a continuous emission monitoring system. The flow rate and volume of flue gas pose significant challenges, including large and irregular chimney sizes, variable gas composition, wide flow velocity ranges, dirt, dust, corrosion, high temperatures, and the absence of straight pipe sections. 4、 There are five modes of transportation: railway and highway, aviation, water transportation, and pipeline transportation. Although pipeline transportation has long existed, its application is not widespread. With the prominent environmental issues, the characteristics of pipeline transportation have attracted peoples attention. Pipeline transportation must be equipped with flow meters, which are the eyes of control, distribution, and scheduling, as well as essential tools for safety monitoring and economic accounting. 5、 The 21st century of biotechnology will usher in the century of life sciences, and industries characterized by bi
