石油产品的输出计量装置的核心是一个包括流量计在内的定量系统。文中介绍了定量系统主要设备的型号、特性及使用范围;五种油品输出计量控制装置的结构及使用范围;以及油品输出计量装置的四种检验方法。 作者对定量机构中的定量计选型,认为电子式定量计的功能优越于其它型号定量计,其特点是可以在控制室内密集型安装,便于远传集中控制和显示,并能提供二段控制信号。关于计量装置的检验无论采用何种方法,都应考虑到正在使用的流量计精度与校正时精度的一致性,会随着环境变化和时间的变化而有所差异。同时建议建立管理机构、各项管理制度及制订油品计量法规。
At the heart of the output metering device for petroleum products is a dosing system that includes a flow meter. This paper introduces the model of the main quantitative system equipment, features and scope of use; five kinds of oil output metering control device structure and scope of use; and oil output metering device of the four test methods. The author of quantitative institutions in the quantitative selection, that the function of electronic quantitative superior to other models of quantitative, which is characterized by intensive control room can be installed for remote centralized control and display, and can provide two control signal. No matter what method is used, the accuracy of the meter in use and the accuracy of the calibration should be taken into consideration. The accuracy of the meter will vary depending on the environment and the time. At the same time, it is suggested to set up management agencies, various management systems and formulation of oil metering laws and regulations.
