阻抗式过环空找水仪校准问题分析

Calibration Problem Analysis on Annular Water Detector of Impedance Type

影响阻抗式过环空找水仪校准效率的因素有很多,为了提高校准效率,实现量值传递,通过现场边校准边维修,发现集流伞布大小、含水率计故障、中心管密封程度是影响校准效率的主要因素。得出伞布宽度在190 mm^193 mm、集流伞开度与套管规接触段长度在30 mm^50 mm,中心管与薄壁筒装完伞不透光时比较合适。

There are ninny factors that influence the impedance type annular water detector calibration efficiency. In order to improve the calibra- tion efficiency and value transfer, through the field calibration and maintenance, find out the major factors affecting the calibration efficiency are umbrella cloth size, water cut meter fault, the center tube sealing. Arrived at when the umbrella cloth width in 190-193mm, umbrella opening and contact length of casing rules in 30-50ram, the central tube and the thin wall cylinder loaded umbrella opaque are more appropriate.
