Interpretation of Application Notes for Steam Flow Meters-

The steam flow meter is a commonly used flow measuring instrument, which is mainly used for measuring the average fluid flow in industrial pipelines. It has the advantages of wide measuring range, high precision, easy maintenance and flexible use.

 1. Industrial production process
The flow meter is one of the main types of instruments in process automation instruments and devices. It is widely used in metallurgy, electric power, coal, chemical industry, petroleum, transportation, construction, textile Food, medicine, agriculture, environmental protection and people\'s daily life and other areas of the national economy are important tools for developing industrial and agricultural production, saving energy, improving product quality, improving economic efficiency and themanagerial level, and occupy an important position in the national economy. In process automation instruments and devices, flowmeters serve two main functions: as a sensing instrument for a process automation control rol system and as a total counter to measure the quantity of materials.
2. 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 petroleum, liquefied petroleum gas, steam) and energy-carrying working environment (compressed air, oxygen, nitrogen, hydrogen, water), etc. Energy metering is an important way to scientifically manage energy, achieve energy saving and consumption reduction, and improve economic benefits. Flow meters are an important part of energy measurement instruments. Yard energy sourcesSystems such as water, man-made gas, natural gas, steam and oil all use a very large number of flowmeters. They are indispensable tools for energy management and economic accounting.
3. Environmental protection project
The discharge of flue gas, waste liquid, sewage, etc. seriously pollutes the air and water resources and seriously threatens the living environment of human beings. The country has enshrined sustainable development as a national policy, and environmental protection will be the focus of the 21st century. To control air and water pollution, management must be strengthened, and the basis of management is quantitative pollution control.
My country is a country where coal is the main source of energy. There are millions of chimneys across the country that are continually blowing smoke into the atmosphere. Controlling flue gas emissions is an important projectworking to eradicate pollution. Each stack should be equipped with flue gas analysis instruments and flow meters to form a continuous emissions monitoring system. The flow of fumes is very difficult. Its difficulty is that the chimney is large in size and irregular in shape, the gas composition changes, the flow rate range is wide, dirt, dust, corrosion, high temperature, the absence of a straight pipe section, etc
4. Transportation
There are five routes: rail, road, air, sea and pipeline. Although pipeline transportation has been around for a long time, its application is not widespread. With the importance of 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 of control, distribution and scheduling, and an essential tool for thesafety control and economic accounting.
V. Biotechnology
The 21st century will usher in the century of life sciences, and industries characterized by biotechnology will develop rapidly. Many substances need to be monitored and measured in biotechnology, such as blood and urine. Instrument development is extremely difficult and there are many varieties.
6. Scientific experiment
Scientific experimentThe required flowmeters are not only numerous, but also extremely varied. According to statistics, a large part of the more than 100 types of flowmeters are used for scientific research. They are not mass produced and sold in the market. Many scientific research institutions and large enterprises have set up special groups to develop special flow meters.
7. Marine Meteorology, Rivers and Lakes
These areas are water channels.open, and generally need to sense the flow velocity and then calculate the flow rate. The speedometer and the flowmeter are based on the same physical principle and the same basis of fluid mechanics, but the principle of the instrument, the structure and the service conditions are very different.
