Among the most important components in alternative fuel dispensing infrastructure, the LPG Pump plays a critical role in ensuring safe, stable, and accurate fuel delivery. Industry professionals are increasingly focusing on technological advancements that improve operational efficiency while meeting stricter performance expectations.

The positive displacement flow meter is the core metrology component in a fuel dispenser. Its primary function is to measure the volume of fuel (gasoline or diesel) delivered during each refueling transaction with high accuracy and repeatability, providing the physical foundation for trade settlement, inventory management, tax compliance, and anti-fraud protection.

As a core metering device, the oil flow meter undertakes the task of quality monitoring throughout the entire process from oil receiving to dispensing at a gas station. It serves as the "digital heart" of the station, and its accuracy and reliability directly determine the health of the entire industry ecosystem.

Xiong Yihui, an employee of the Retail Management Department of the Petroleum retail company, discovered through the fuel nozzle anomaly monitoring program that the No. 15 fuel nozzle at a refueling station had an abnormal flow rate. He immediately organized on-site personnel to follow up and verify, carry out analysis and handling, and promptly initiated the maintenance process. The equipment debugging and repair were completed in the morning of the same day, ensuring the smooth operation of the refueling site.

In February 2025, following the announcement of broad tariffs by the United States on Chinese goods, China imposed retaliatory measures on selected U.S. energy products, including a 15% tariff on liquefied natural gas (LNG) and a 10% tariff on crude oil. As a result, imports of these two fuels from the United States came to an almost complete halt. From a resource endowment perspective, the United States — as the world's largest LNG exporter and a major oil producer — and China — as the world's largest energy buyer — have a natural energy complementarity. However, the recent escalation of the Middle East crisis is reshaping the global energy landscape. The disruption of shipping through the Strait of Hormuz has affected approximately one-fifth of global oil and seaborne natural gas exports, driving up international energy prices.

Due to the near-total disruption of shipping through the Strait of Hormuz, a vital corridor for crude oil and natural gas, China's energy imports saw a sharp decline in April. According to customs data released last Saturday, crude oil shipments fell 20% year-on-year, with petroleum imports also dropping below the previous month's levels. These figures include oil that had already begun shipping from the Gulf prior to the US-Israeli airstrikes on Iran on February 28. The Middle East typically accounts for about half of China's crude oil imports and nearly one-third of its liquefied natural gas (LNG).
