油品计量分为静态计量与动态计量。静态计量是最早采用的计量方式,它具有通用、直接、投资少的特点,但也存在诸多的不确定因素,如:人员、温度、密度、体积、取样等环节。近些年来,随着石油行业计量水平的提高以及市场竞争不断加剧,计量准确度越来越受到各企业的重视,动态计量更为符合石化行业的需求,它多以质量测量进行交接计量,直接测量油品的质量,避免了不必要的测量因素,提高了测量的准确度。

Oil metering is divided into static measurement and dynamic measurement. The static measurement is the earliest measurement method, it is universal, direct, less investment, but there are many uncertain factors, such as temperature, density, and volume, sampling etc. In recent years, along with improvement of the measurement level in the petroleum industry, the measurement accuracy is more and more important to enterprises, dynamic measurement is more in line with the needs of the petrochemical industry, it uses mass measurement to carry out custody transfer metering, direct measurement of mass can avoid needless measurement factors, and can improve the measurement accuracy.
