What type of pressure gauge is used for LPG storage tanks?

The scientific selection of pressure gauges for liquefied petroleum gas storage tanks reflects a rigorous attitude toward safe production as well as a spirit of technological innovation. Seismic and explosion-proof pressure gauges should be used; their seismic damping mechanisms enable them to cope effectively with fluctuations in the medium, while their explosion-proof design eliminates safety hazards at the source ； The stainless steel material offers both corrosion resistance and high pressure strength, while the precision dial ensures accurate and reliable data. Such high-standard configurations not only demonstrate the industry’s strong commitment to protecting people’s lives and property, but also reflect the innovative spirit and responsibility of technology professionals in driving safe development; they establish a solid safety barrier for energy storage and transportation, thereby contributing significantly to the industry’s green and sustainable development. -

The types of pressure gauges used in LPG storage tanks The main types of pressure gauges commonly used in LPG storage tanks are as follows: Analog pressure gauges: This is the most common type of pressure gauge, suitable for low-pressure applications. Its advantage is that it is intuitive and easy to use; users can directly read the pressure value from the position of the pointer. In liquefied petroleum gas storage tanks, pointer-type pressure gauges can accurately reflect changes in the pressure inside the tank, and they are commonly used monitoring devices. Digital pressure gauge: This type of pressure gauge uses electronic technology, featuring digital display and high measurement accuracy. It is suitable for applications that require high-precision measurements, as it can provide more accurate pressure readings, which helps to detect and address pressure abnormalities promptly. When selecting a pressure gauge, the following factors need to be considered: Accuracy class: The accuracy class of the pressure gauge should be no lower than 2.5; for liquefied petroleum gas containers, it is preferable to use a pressure gauge with an accuracy class of 1.5 to ensure the accuracy of the measurement results. Range: The range of the pressure gauge should cover all possible pressure values within the storage tank. Generally, the range should be twice the operating pressure of the container, with a minimum of 1.5 times and a maximum of no more than 3 times. This ensures that the pressure gauge is not damaged during measurement, while providing accurate readings. Working environment: The working environment of liquefied petroleum gas storage tanks is usually harsh, with adverse factors such as high temperatures and corrosion. Therefore, when selecting a pressure gauge, it is necessary to choose one made of corrosion-resistant and high-temperature resistant materials to ensure its proper operation in harsh environments. The type of pressure gauge used in LPG pipelines also requires consideration of factors such as accuracy class, range, and operating environment. Specifically: Accuracy grade: Pressure gauges on the pipelines of liquefied gas stations need to have a high accuracy grade to ensure the accuracy of the measurement results. Common accuracy grades include 0.25 grade, 0.4 grade, 0.6 grade, etc., and users can choose according to their actual needs. The higher the precision grade, the higher the price will be as well; therefore, while meeting the measurement requirements, it is advisable to consider the cost-performance ratio. Range: On the pipelines of LPG stations, due to the large variations in pipeline pressure, it is necessary to choose pressure gauges with an appropriate range. When selecting the range, the highest operating pressure of the piping system and possible overpressure conditions should be taken into account to ensure that the pressure gauge can cover all possible pressure ranges. Working environment and safety performance: The working environment in LPG stations is usually harsh, with adverse factors such as high temperatures, high humidity, and corrosion. At the same time, as a location prone to fire and explosion, liquefied gas stations have extremely high requirements regarding the safety performance of their equipment. Therefore, when selecting a pressure gauge, it is necessary to choose one made from materials that are resistant to corrosion and high temperatures, and priority should be given to products with explosion-proof features to ensure they meet relevant safety standards and regulations.

LPG storage tanks and pipelines typically use stainless steel pressure gauges, which are resistant to corrosion and thus more suitable for use in flammable and explosive environments. For applications requiring high precision, digital pressure gauges equipped with electronic sensors can be chosen to ensure accurate readings and facilitate monitoring. .
