Abstract	本发明属于光纤传感技术领域，尤其涉及一种液体密度计和液体密度测量系统。该密度计包括套管和在套管内固定级联设置的两个FPI结构，每个所述FPI结构的末端设置有与待测液体接触并用于测量所述待测液体内压强的F‑P腔结构，两个FPI结构位于所述套管内的不同高度，以测量不同位置处的液体压强；每一个FPI结构将测量的液体压强通过内部的光纤输出，每一个FPI结构内部光纤的一端与所述F‑P腔结构接触，另一端延伸出所述套管。本发明提供的液体密度计，体积小、灵敏度高且具有温度自动补偿的特点。
Other Abstract	The invention belongs to the technical field of optical fiber sensing, and particularly relates to a liquid densimeter and a liquid density measuring system. The densimeter comprises a sleeve and twoFPI structures which are fixedly arranged in the sleeve in a cascade manner, wherein a F-P cavity structure which is in contact with liquid to be measured and is used for measuring the pressure intensity in the liquid to be measured is arranged at a tail end of each FPI structure; the two FPI structures are positioned at different heights in the sleeve in order to measure the liquid pressure intensities at different positions; each FPI structure is used for outputting the measured liquid pressure intensity through an internal optical fiber; and one end of the internal optical fiber of each FPIstructure is in contact with the F-P cavity structure, and the other end extends out of the sleeve. The liquid densimeter provided by the invention has the characteristics of small volume, high sensitivity and automatic temperature compensation.
