摘要
论述了加油站油气排放控制与运油罐车、地下储罐量油方式的关系,概述了我国加油站量油方式的现状,以及人工测量和液位仪密闭自动测量两种量油方式。综述了电容式液位仪、超声波液位仪和磁致伸缩式液位仪的量油原理、特点及发展趋势,重点介绍了磁致伸缩技术,并结合汽油流转过程中油气密闭性控制的重要性及储油罐的管理要求,展望了未来加油站量油方式的技术发展趋势。
The relation of oil and gas emission control with oil tank truck as well as underground oil tanker was discussed to overview refueling methods of China oil gas stations in present, which methods had artificial measurement and airtight automatic liquid level meter measurement. The principle, characteristics and development trend were summarized for capacitive level meter, ultrasonic liquid level meter and magnetostrictive meter. The discussion focused on magnetostrictive technology and management requirements of gasoline transfer process control for oil and gas storage tank. Technology development trend in the future refueling way of oil gas station was prospected.
