Flow meter application area

Flow meter application field 1. Industrial production process 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, Various fields of national economy such as medicine, agriculture, environmental protection, and people’s daily life are important tools for the development of industrial and agricultural production, energy conservation, improvement of product quality, and improvement of economic efficiency and management level. They play 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 measuring instrument and the quantity of the measured material of the process automation control system.

2. 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 devices. The commonly used energy sources such as water, artificial gas, natural gas, steam, and oil products use a very large number of flow meters, which are indispensable tools for energy management and economic accounting. 3. The environmental protection project's emissions of flue gas, waste liquids, and sewage seriously pollute the atmosphere and water resources and seriously threaten 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. The air and water pollution must be controlled, and management must be strengthened. The basis of management is the quantitative control of the amount of pollution. The flowmeter has an irreplaceable position in terms of smoke emission, sewage, and exhaust gas treatment flow measurement.

China is a country where coal is the 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 size of the chimney is large and its shape is irregular, the gas composition changes indefinitely, the flow velocity range is large, dirt, dust, corrosion, high temperature, and no straight pipe sections.

4. There are five ways of transportation: railway, highway, aviation, water transportation and pipeline transportation. Although pipeline transportation has already existed for a long time, its application is not widespread. With the outstanding environmental protection issues, the characteristics of pipeline transportation have attracted people's attention. Pipeline transportation must be equipped with a flowmeter. It is the eye of control, distribution and dispatch, and it is also an essential tool for safety supervision and economic accounting.

5. In the 21st century, biopharmaceuticals will usher in the century of life sciences, and industries that are characterized by biotechnology will develop rapidly. There are many substances that need to be monitored and measured in biotechnology, such as blood and urine, etc.; the pharmaceutical industry also lacks or controls the flow meter for various pharmaceutical formulations and liquid formulation components. Instrument development is extremely difficult and varied.

6. Scientific Experiments Scientific experiments require not only a large number of flow meters, but also a variety of flow meters. According to the statistics, more than 100 kinds of flowmeters are required for scientific research. They are not mass-produced and are sold on the market. Many scientific research institutions and large companies have specialized teams to develop special flowmeters.

7. In areas such as oceans and rivers and lakes, open flow paths are generally used, and flow rates are generally measured and then the flow rate is estimated. The physical principles and fluid mechanics basis on which the flowmeter and flowmeter are based are common, but the principle and structure of the instrument and the premise of use are very different.
