自动密度仪测定原油密度及注意事项
DENSITY DETERMINATION OF CRUDE OILS AND POINTS FOR ATTENTION
摘 要
介绍了U型振荡管密度仪测定原油密度的方法、原理，以及实验中应注意的混样、进样、测定和结果计算等环节。将原油样品注入清洁、干燥的控温U型样品振荡管中，振荡管的振动频率随着振荡管中样品质量不同而变化，通过由已知密度的标准物质得到的校正数据可测定原油样品的密度。

Abstract
A small portion of crude oil sample is introduced into the clean, dry and temperature-controlled oscillating U-tube, the change in oscillating frequency caused by the change in the mass of the U-tube is used in conjunction with U-tube constants previously determined by measuring the oscillation frequencies when the U-tube is filled with calibration fluids of known density to determine the density of the sample. This article present the method & principle for determination of density of crude oils by digital density analyzer and points for attention.
