摘要
石油和石油产品的密度是其重要的理化性质之一,对其进行准确的测定具有很重要的现实意义。文中在研究现有的超声波传播时间法密度计和相位差法密度计的基础上,针对它们的不足,提出了一种新的测量技术——超声波传播时间整零分测技术,从很大程度上提高了密度在线检测的精度。
Density of petroleum and petrochemicals is an important physical-chemical quality. To measure it accurately is important and has practical significance. This paper proposes a new method for measuring oil density, that is, to measure the whole time and the excess time of ultrasonic spreading respectively. The method overcomes for the disadvantages of measuring time differences and measuring phase changes, and greatly improves precision of the measurement.
