Flow rate is an important parameter in the automated production process of petroleum, metallurgy, electric power, chemical, pharmaceutical, food and other industries. In modern industrial production, the flow metering is inseparable from process monitoring to product quality inspection. Flow metering supervision and control level is also directly related to production quality, production efficiency and full utilization of energy. Therefore, flow metering is an important guarantee for industrial production, product quality and technological progress. It can be said that flow metering is an industrial production eye.

Flow measurement is also closely related to people's health and safety. For example, whether the domestic gas meter is accurate and safe; the amount of steam, the metering of the tap water meter is stagnation accuracy, etc., all belong to the scope of flow metering.

Flow metering is also used for trade settlement. From the international trade settlement of crude oil, aviation fuel, and natural gas to the trade settlement of energy consignment parties in various industries in China, it is necessary to use a flow meter for settlement. The annual amount of oil flow for trade settlement is calculated in the amount of 100 billion yuan.

As the international community continues to improve the world, environmental protection has become the most urgent task in the 21st century, such as the measurement of smoke, sewage and sulfur dioxide emissions, and the measurement of dust in the atmosphere.

In recent years, due to the vigorous development of natural gas fields, urban natural gas and liquefied petroleum gas have been widely used. Due to the multi-parameter, multi-component, continuous metering and non-recoverable and long-distance pipeline transportation and storage characteristics, the measurement accuracy of natural gas flow meter will be affected by many factors on site, that is, it needs to have perfect value. The transmission and traceability system can guarantee the flow metering standard, and the flow metering instrument is accurate and reliable, so that the metering accuracy can be controlled within a reasonable range that can be accepted by both the supply and demand sides. Therefore, the accuracy of these flowmeter verification and calibration is the most important link in the flow value transfer or traceability chain, not only related to the economic interests of the trade partners, but also the important technical basis for ensuring the uniformity of the flow value to achieve the relevant magnitude. Accurate and consistent with international standards.
