摘　　要：分析了亚临界汽包锅炉差压水位计"传统平衡容器"在水位测量中的不足之处,由于参比水柱温度对水位测量有较大影响,而平均温度随环境温度变化大且不易求得。应用改进的HL2512P平衡容器,并在水位测量中采用简化的温度补偿公式,提高了汽包水位测量的准确性。同时总结了消除汽包水位差压测量误差的主要方法。This paper analyzed the influence of ＂traditional balance con ment of drum water level （because average environment temperature greatly and too difficult to get a value）. It has explained the principle o balance container which simplified temperature compensation formula new app methods lication can improve the accuracy of level measurement. At the same time, main to eliminate the error of level measuring have been summarized.
