摘要
电接点水位计、就地水位计是超高压锅炉最重要的测量仪表，其测量存在严重误差，致使锅筒实际运行水位长期高于设计值。华能淮阴电厂采用ＧＪＴ测量筒取代普通测量筒，消除了测量误差，从而解决了锅筒高水位运行问题。
Abstract The remote water level indicator and local water indicator are the prime instruments for high boiler, super high pressure boiler and subcritical pressure boiler. Its sampling severe error shows that the practical operation water level of the drum is realy much higher than the design value. Huaneng Huayin Power Plant which replacing normal sampling water column by GJT high precison sampling water column, eliminated the sampling error and resoluted the drum high water column' operation problems.
