摘要
Abstract
When measuring the density of crude oil by U-shaped vibrating tube method,the crude oil viscosity would affect the density test results,which would lead to the deviation of crude oil trade settlement.The principle and standard of U-shaped vibrating tube method measuring crude oil density were introduced,and the effects of viscosity of different types of crude oil on the density test results were studied.The results show that when using the digital density meter without viscosity correction function,it should be strictly in accordance with the requirements of the standard,improve the test temperature and reduce the effects of viscosity.When using the digital density meter with viscosity correction function,it should pay attention to instrument calibration according to the manufacturer’s specifications to make test results more reasonable.关键词
