The flow meter is one of the major instruments in process automation instrumentation and devices. It is widely used in metallurgy, electric power, coal, chemical industry, petroleum, transportation, construction, textile, food, medicine, agriculture, environmental protection and daily life of the people. In various fields such as the national economy, it is an important tool for developing industrial and agricultural production, saving energy, improving product quality, and improving economic efficiency and management. It plays an important role in the national economy. In the process automation instrument and device, the flow meter has two major functions: as the total amount of the instrumentation of the process automation control system and the measurement of the quantity of the material.
Second, energy metering energy is divided into primary energy (coal, crude oil, coal bed methane, petroleum gas and natural gas), secondary energy (electricity, coke, artificial gas, refined oil, liquefied petroleum gas, steam) and energy-carrying working fluid (compression Air, oxygen, nitrogen, hydrogen, water, etc. Energy measurement is an important means of scientifically managing energy, realizing energy saving and consumption reduction, and improving economic efficiency. Flow meters are an important part of energy metering instruments. Water, artificial gas, natural gas, steam, and oil are all commonly used energy sources. They use an extremely large number of flow meters from Chengfeng Flow Meter Co., Ltd. They are not energy management and economic accounts. Missing tools.
III. Environmental Protection Engineering The emission of fumes, waste liquids, and sewage seriously pollutes the atmosphere and water resources, seriously threatening the human living environment. The country regards sustainable development as a national policy, and environmental protection will be the biggest issue in the 21st century. Air and water pollution must be controlled and management must be strengthened. The basis of management is the quantitative control of pollution.
China is a country with coal as its main energy source. There are millions of chimneys in the country that continuously emit smoke to the atmosphere. Flue gas emission control is an important project to eradicate pollution. Each chimney must be equipped with flue gas analysis instruments and flow meters to form a continuous emission monitoring system. The flow rate of the flue gas is very difficult. Its difficulty is that the chimney is large in size and irregular in shape, the gas composition is indefinite, the flow velocity range is large, dirt, dust, corrosion, high temperature, and no straight pipe sections.
