Thermal gas flowmeter has become the ideal choice for flare gas measurement because of accurate measurement, wide range ratio, adapt to complex environment, easy installation and maintenance and wide application, especially in petrochemical and other industries with outstanding performance.
Flare gas is more recommended thermal gas flowmeter based on the following reasons:
First, the measurement principle and accuracy
Thermal gas flowmeter is designed based on the principle of thermal diffusion, and adopts the constant temperature difference method to measure the gas accurately. This measurement method enables the thermal gas flow meter to directly measure the mass flow rate of the gas without the need for temperature and pressure compensation. This feature ensures high accuracy in flare gas measurement, because the temperature and pressure of flare gas may fluctuate greatly, and traditional flow meters need to carry out complicated compensation calculations, while thermal gas flow meters can avoid this problem.
Second, wide range ratio and adaptability
Thermal gas flowmeter has a very wide range ratio, theoretically up to 1:1000, which means that it can achieve from a very small range to a very large range of measurement. This is very important for flare gas measurement, as flare gas flow can fluctuate greatly due to operating conditions, process changes and other factors. The wide range ratio of the thermal gas flow meter allows it to accommodate such flow variations, ensuring continuity and accuracy of measurement.
Third, the adaptability of the complex environment
Flare gas may contain dust, solid particles, oil, moisture and other impurities, which puts forward high requirements for the flowmeter's corrosion resistance, resistance to media corrosion and media insensitivity. Thermal gas flowmeter excels in these aspects, its sensor has no moving parts and pressure sensing parts, not subject to vibration on the measurement accuracy, and insensitive to impurities in the medium. In addition, the thermal gas flowmeter also has the advantages of good seismic performance, long service life, and can operate stably in harsh industrial environments.
Fourth, the convenience of installation and maintenance
Thermal gas flowmeter installation and maintenance is relatively simple. Its overall design is compact, digital circuit measurement makes accurate measurement and easy maintenance. In the case of site conditions allow, can be achieved without stopping the installation and maintenance (requires special customisation), which reduces the impact on production. At the same time, the thermal gas flowmeter connection specifications are diverse, including threaded connection, French card mounted, flange connection and other ways to meet different pipeline requirements.
V. Wide range of applications
Thermal gas flowmeter is widely used in many industries, including petrochemical, electric power, metallurgy, food and beverage, environmental protection and pharmaceuticals. In the petrochemical industry, it is particularly suitable for the metering and control of natural gas, liquefied natural gas (LNG), liquefied petroleum gas (LPG) and other gases. The application experience in these industries has proved the reliability and accuracy of thermal gas flow meters in complex environments, and has also provided strong support for their application in flare gas measurement.
In summary, flare gas is more recommended thermal gas flowmeter because of the accuracy of its measurement principle, wide range ratio adaptability, adaptability to complex environments, ease of installation and maintenance, and a wide range of application areas. Together, these factors make thermal gas flow meters the ideal choice for flare gas measurement.
