摘要(Abstract)：
汽包水位测量值作为机组运行的重要监视参数,其准确性直接关系到机组的安全稳定运行。通常单元机组都要配备若干就地云母水位计、电接点水位计和差压式水位计,各种水位计由于测量原理的不同,各有优缺点。结合北仑发电厂二期汽包水位测量问题,分析存在测量偏差的原因,并提出了改进措施。
Drum level as the critical parameter for the unit running,its veracity is related with the unit safety. Usually,a unit is equipped with several types level meter,for example mica level meter,electrode level meter and different pressure level meter.Because of these level meter's measurement principles are not same,so they have their own advantage and shortcoming.This paper discusses the improvement on drum level measurement method and the reason of measurement error which has existed since the phase 2 units were put into production.
