Helium, as a scarce single atom rare gas, has the characteristics of colorless, odorless, non-toxic, strong inertness, and extremely low boiling point. It is widely used in high-end fields such as electronic semiconductors, aerospace, medical imaging, low-temperature superconductivity, and petrochemicals, and is an irreplaceable strategic resource. China's helium resources are extremely scarce, with over 95% relying on imports. Helium recovery technology has become the core path to reduce production costs, improve resource utilization, and ensure supply chain stability. The helium recovery process covers the entire process of "collection purification storage transportation reuse", with the core goal of separating and purifying helium from the exhaust gas to meet reuse standards. The precise monitoring of parameters such as composition, purity, pressure, and temperature throughout the entire process directly determines the recovery efficiency, helium quality, and process operation safety. As the "eyes" and "nerve center" of helium gas recovery process, online instruments run through the entire recovery process, responsible for real-time capturing of various parameter changes, accurate feedback of process status, and linkage optimization of equipment operation. They are essential supporting equipment to ensure the stable and efficient operation of helium gas recovery process, ensure the quality of recovered helium gas meets standards, and avoid production risks.
