Flowmeter Applications - Focus on Microfluidic Control Technology

As we all know, the types of flow meters and their application fields have a wide range of practical applications and are the same things that science and development are indispensable. Here we explain the application of the flow meter.

The first is the energy sector

Energy is divided into primary energy (coal, crude oil, coalbed methane, petroleum gas, etc.), secondary energy (electricity, refined oil, liquefied petroleum gas, steam, etc.) and energy carrying medium (compressed air, oxygen, 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. The commonly used energy sources such as water, natural gas, steam and oil products use a very large number of flow meters, which are indispensable tools for energy management and economic accounting.

Second, the industrial production process

The flow meter is one of the major instruments in process automation instrumentation and devices. It is widely used in the national economy of metallurgy, chemical industry, petroleum, transportation, construction, textile, food, medicine, agriculture, environmental protection, and people’s daily life. The field is an important tool for the development of industrial and agricultural production, energy conservation, improvement of product quality, and improvement of 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.

Third, transportation

There are five ways to transport: railway and highway, aviation, water transport, 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, which is the eye of control, distribution and dispatch, and an essential tool for safety monitoring and economic accounting.

IV. Environmental Protection Engineering

Flue gas, waste liquids, sewage and other medium discharges, seriously pollute the atmosphere and water resources, but also a serious threat to the human living environment. State environmental protection will be the biggest topic 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 changes indefinitely, the flow velocity range is large, corrosion, high temperature, and no straight pipe sections.

V. Scientific experiment

The scientific experiment requires 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 special teams to develop special flowmeters.

VI. Biotechnology

The century of life science will usher in the first century, and the industry characterized by biotechnology will develop rapidly. There are many substances that need to be measured and measured in biotechnology, such as blood and urine. Instrument development is extremely difficult and varied.
