In the liquefied gas industry, flow meters are the core equipment that ensures precise measurement and efficient transportation. And for flow meters like lpg flow meter, there are many little-known secrets hidden within them.
The valve body of the lpg flow meter is made of cast aluminum, while the piston is made of brass. The cast aluminum is not merely for lightness; it also has excellent corrosion resistance, enabling long-term stable operation in the special environment of liquefied gas and preventing the decline in measurement accuracy due to corrosion. The brass piston not only has the appropriate hardness to ensure the sealing performance when combined with the valve body, but also can reduce friction loss and extend the service life of the equipment. This material combination has been verified as a "golden combination" through numerous experiments and practical applications.
The marked operating temperature range of this device can reach 60℃. This temperature setting is not arbitrary. During the transportation of liquefied gas, the temperature may change due to environmental factors and equipment operation. If the flowmeter does not have sufficient temperature resistance, the thermal expansion and contraction of internal components will affect the measurement accuracy and even damage the equipment. However, this flowmeter precisely controls the thermal properties of its materials and ingeniously designs its internal structure, enabling it to maintain stability within a wide temperature range. Even in hot summer or when the equipment continues to operate and heats up, it can still reliably measure.
It can adjust the displacement according to the demand, and behind this is a sophisticated regulating mechanism. Different from some simple and crude regulating methods, the displacement regulating components of lpg flow meter have been finely polished. The regulating process is smooth and highly accurate, and even a small adjustment range can correspond to the precise change of the flow rate. It can meet the differentiated and precise requirements for flow measurement in various scenarios, such as filling from small bottled liquefied gas tanks to large tanker loading and unloading, and provides strong support for the flexible adjustment of production and operation.
Under complex working conditions such as the transportation of liquefied gas from underground tanks and batch gas filling, there are often situations like pressure fluctuations and the presence of gas in the medium. The internal structure of the liquefied gas flowmeter is specially designed to reduce the interference of pressure fluctuations on measurement, and it can also adapt to certain gas-containing liquefied gas media, ensuring accurate measurement even under these seemingly unfavorable conditions. This is an important "hidden skill" that enables it to be widely used in various scenarios.
These little secrets allow the liquefied gas flowmeter to play a key role in the precise measurement and efficient transportation of liquefied gas in the liquefied gas industry, and are the important "behind-the-scenes contributors" for the stable operation of the industry.
