1. Energy Metering
Energy is divided into primary energy (coal, crude oil, coalbed methane, LPG and natural gas), secondary energy (electric power, coke, artificial gas, refined oil, liquefied petroleum gas, steam) and carrying energy (compressed air, oxygen, nitrogen, hydrogen, water). Energy metering is an important means to manage energy scientifically, achieve energy saving and improve economic efficiency. The flow meter is an important part of energy metering instruments. Very large quantities of flow meters are used in common energy such as water, artificial gas, natural gas, steam, and oil. They are an indispensable tool for energy management and economic accounting.
2. The process of Industrial Production
Flow Meter is one of the large-class instruments in the process automation instrument and device, which is widely used in various areas of the national economy like metallurgy, electric power, coal, chemical industry, petroleum, transportation, construction, textile, food, medicine, agriculture, environmental protection and people's daily life. It is an important tool which occupies a vital position in developing industrial and agricultural production, saving energy, improving product quality, improving economic efficiency and management level. In the instrumentation and device of process automation, the flow meter
has two main functions, as the process automation control system's measuring instrument and the total table for the quantity of measured materials.
3. Biological Technologies
The 21st century will usher in the Century of Life Science. A lot of substances, such as blood, urine and so on need to be monitored and measured by biological technology. The instrument is very difficult to develop with a wide variety.
There are five ways: railway, air, water, and piping. The characteristics of pipeline transportation have aroused people's attention with the prominence of environmental protection issues. The pipeline transportation must equip with the flow meter, which is the control, the distribution and the dispatch eye as well as the essential tool for safety supervision and the Economic accounting.
5. Scientific Experiments
Scientific experiments require not only a large number of flow meters but also an extremely complex variety. According to the statistical, among more than 100 kinds of flow meters, a large part of them are used for scientific research. They do not a mass production or in the market. Many scientific research institutions and large enterprises set up special groups to develop dedicated flow meter.
6. Environmental Protection Projects
The emission of flue gas, waste water, sewage and so on seriously pollute the atmosphere and aquatic resources as well as threaten the environment of human existence seriously. Sustainable development has been made as a national policy by the State and environmental protection will be the biggest issue in the 21st century. We should control and strengthened management of the pollution of air and water, and the basis of management is the quantitative control of pollution.
