- 摘要:
- 为提高和确保天然气流量计量准确度，国内外都建立了天然气流量实流检测装置。气体流量计量环道检测技术作为一种新型的流量实流检测技术，已在天然气计量领域得以应用，技术也日趋成熟。但目前国内还没有采用该技术的天然气流量计量检测装置，相关关键技术尚属空白。区分了天然气流量计量检测装置的直排方案和环道方案，介绍和对比了国内外气体流量计量环道检测装置的技术指标，剖析了环道检测装置的基本组成和各部分的功能，以及环道检测装置的基本工艺流程，探讨了环道检测方案的几项关键技术，为天然气流量计量环道实流检定站的设计提供理论依据。
In order to enhance and ensure the measuring accuracy of gas flow meter， natural gas flow meter verification facilities have been established at home and abroad. As a new technology of gas flow meter calibration and verification， re-circulation design has been applied in the field of natural gas flow meter verification and the technology is becoming more and more mature. But so far， there is still no natural gas flow meter verification facility adopting re-circulation design and relative key technologies in China. Pointed out are differences between re-circulation design and direct discharge design of such gas flow meter verification facility and introduced and compared are gas flow meter verification and calibration facilities with re-circulation design in the world， analyzed are fundamental elements of such facilities， their functions and basic flow progress， discussed are some key technologies of the facilities， which has important reference values for re-circulation design of gas flow meter verification facilities.
