摘要(Abstract)：
对影响汽包水位信号的因素进行分析,并在此基础上进行改造,通过改变变送器安装位置、改变取样管加热方式等措施,取得了较为明显的效果。
With boiler drum water level in normal range is very important.So,the steam drum water level measurement system must be accurate and reliable.This article introduces running and maintenance experience of drum water level measurement in Jiaxing Power Plant,analyzes influencing factors to differential pressure type level measurement,and discovers primary cause of measurement deviation.Based on these,transformation for drum water level measurement had obtained more obvious effects.
