EnglishFlow measurement is widely used in various fields of industrial and agricultural production, national defense construction, scientific research, foreign trade, and people's lives.
In the petroleum industry, flow measurement runs through the entire process from oil extraction, transportation, refining, smelting and processing to trade sales, and flow measurement is inseparable from any link. Otherwise, the normal production and trade exchanges of the oil industry will not be guaranteed. In the chemical industry, inaccurate flow measurement can cause imbalance in the distribution ratio of chemical components, which cannot guarantee product quality, and serious production safety accidents may occur. In the production of the electric power industry, the measurement and regulation of the flow of liquid, gas, steam and other media occupies an important position. The accuracy of flow measurement is not only of great economic significance for ensuring that power plants operate under the *parameters, but also with the development of high-temperature, high-pressure and large-capacity units, flow measurement has become an important part of ensuring the safe operation of power plants. If the instantaneous feed water flow of a large-capacity boiler is interrupted or reduced, it may cause a serious dry pot or tube burst accident. This requires the flow measurement device not only to achieve accurate measurement, but also to send out an alarm signal in time. In the steel industry, the flow measurement of circulating water and oxygen (or air) in the steelmaking process is one of the important parameters to ensure product quality. In light industry, food, textile and other industries, flow measurement is also inseparable.
In agriculture, such as farmland water conservancy, weather and wind speed, and even some agricultural machinery, such as motorized sprayer, water pump characteristic test, also need flow measurement.
In the construction of national defense, with the development of space technology, quite high requirements are put forward for flow measurement. For example, the nuclear power control of spacecraft and nuclear submarines is inseparable from the flow meter; the rocket generator test runs a passive large amount of liquefied fuel. If the flow is not accurate, not only will the economic loss be huge, but the range will also deviate by several thousand kilometers; chemical defense equipment Flow meters are also indispensable; some military projects even use thousands of flow meters.
In terms of scientific research and foreign trade, flow measurement also occupies an important position and role. Tap water, gas, natural gas, oil, etc., which are closely related to people's daily life, all use flow meters for measurement.
