摘要
油罐的油品计量,不仅是液位测量,而且是一项综合了各种参数的复杂的计量系统。通过三种主要的油品储罐计量方案的比较,分析了影响油罐库存管理和计量交接精度的各种因素,对误差产生的原因和修正的方法进行了探讨。基于液位和质量测量技术的混合式计量系统可以作为一个比较完善的油罐自动计量系统方案。
Oil tank gauging system is a complex system that integrates various parameters and is not limited to the level measurement. Three kinds of oil tank gauging schemes are introduced. Various influence factors of management of tank inventory and custody transfer accuracy are analyzed, the reasons of the error caused and ways to compensate are discussed. Hybrid gauging system based on level and mass measurement technology is introduced as a complete and perfect oil tank gauging system.
