Orifice flowmeter application field description Flowmeter selection quote calculation

Orifice flowmeter applications and a wide range of applications, flow measurement technology and instrumentation have the following areas.

First, energy measurement
Energy is divided into primary energy (coal, crude oil, coalbed methane, petroleum gas and natural gas), secondary energy (electricity, coke, artificial gas, refined oil, liquefied petroleum gas, steam) and energy-carrying refrigerant (compressed air, oxygen, Nitrogen, hydrogen, water, etc. Energy metering is an important means of scientifically managing energy, achieving energy conservation and reducing consumption, and improving economic efficiency. Flow meters are an important part of energy metering. Water, artificial gas, natural gas, steam and oil use a very large number of flow meters, which are indispensable tools for energy management and economic accounting.
Second, the industrial production process
Flow meter is one of the large-scale instruments in process automation instruments and devices. It is widely used in metallurgy, electric power, coal, chemical, petroleum, transportation, construction, textile, food, medicine, agriculture, environmental protection and people's daily life. In all areas of 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 level. It plays an important role in the national economy. In process automation instruments and devices, flow meters have two functions: as a test instrument for the process automation control system and a total meter for measuring the quantity of materials.
    Third, environmental protection engineering
The emissions of flue gas, waste liquid, sewage, etc. 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. Air and water pollution must be controlled, management must be strengthened, and management is based on 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 into the atmosphere. Flue gas emission control is an important project to cure pollution. Each chimney must be equipped with a flue gas analysis instrument and a flow meter to form a flail emission monitoring system. The flow rate of flue gas is very difficult. The difficulty is that the chimney is large in size and irregular in shape, the gas composition changes indefinitely, the flow rate range is large, dirt, dust, corrosion, high temperature, and no straight pipe section.
Fourth, transportation
There are five ways: railway, air, water, and pipeline transportation. Although pipeline transportation has already existed, the application is not common. With the outstanding environmental protection issues, the characteristics of pipeline transportation have attracted people's attention. Pipeline transportation must be equipped with a flow meter, which is the eye for control, distribution and dispatch, and is an essential tool for safety monitoring and economic accounting.
V. Biotechnology
The 21st century will usher in the century of life sciences, and industries characterized by biotechnology will develop rapidly. There are many substances that need to be monitored in biotechnology, such as blood and urine. Instrument development is extremely difficult and varied.
Sixth, marine meteorology, rivers and lakes
These areas are open flow paths, which are typically measured and then the flow is estimated. The physical principles and hydrodynamics of the flowmeter and flowmeter are common, but the principle and structure of the instrument and the conditions of use vary widely.
    Seven, scientific experiment
The flowmeters required for scientific experiments are not only numerous, but also extremely versatile. According to statistics, a large part of the flowmeters are used for scientific research. They are not mass-produced and are sold in the market. Many scientific research institutions and large enterprises have set up special teams to develop special flowmeters.
