Industrial production
The flowmeter is one of the instrument categories of process automation instrumentation and instrumentation. It is widely used in metallurgy, electricity, coal, chemicals, petroleum, transportation, construction, textiles, food, medicine, agriculture, environmental protection and People's Daily. The national economy in all fields of life is an important tool for the development of industrial and agricultural production, the conservation of energy, the improvement of product quality, and the improvement of economic efficiency and management. It occupies an important position in the national economy. In the process automation instrument and equipment, the flowmeter has two main functions: the detection instrument as the process automation control system and the total number of measurement materials table.
Energy measurement
Energy is divided into primary energy(coal, crude oil, coal bed gas, 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 scientifically manage energy, save energy, reduce energy consumption and increase economic benefits. Flow meters are important components of energy meters, water, artificial gas, natural gas, steam and petroleum products. These commonly used energy sources use a large number of flow meters and they are indispensable tools for energy management and economic accounting.
Environmental Engineering
The discharge of flue gas, waste liquid and sewage has seriously polluted the atmosphere and water resources and threatened the human living environment. China regards sustainable development as its national policy, and environmental protection will become one of the biggest problems in the 21st century. In order to control air and water pollution, it is necessary to strengthen management, which is based on pollution quantitative control.
China is a country that uses coal as its main energy source. Millions of chimneys constantly emit smoke into the atmosphere. Flue gas emission control is an important pollution project. Each chimney must be equipped with a flue gas analyzer and instrument, and even a discharge monitoring system. The flue gas flow is very difficult because the chimney is large in size, irregular in shape, variable in gas composition, and has a large flow range. There is no direct pipe section, where it is smut, dust, corrosion, and high temperature.
transportation
There are five ways: railways, highways, aviation, water and pipelines. Although pipeline transportation has already existed, its application is not universal. With the outstanding environmental protection problems, the characteristics of pipeline transportation have attracted people's attention. Pipeline transportation must be equipped with flowmeters, which are necessary tools for control, distribution and dispatch of eyes, as well as security monitoring and economic accounting.
