摘　　要：电站锅炉汽包水位的精确测量是机组运行中的重要参数依据 ,但目前进行热工测量、运行监控的差压测量法水位计所给出的水位高h只有进行汽包压力修正后才能较准确地反映汽包真实水位。对此 。Accurate measurement of water-level in the drum of utility boilers is an important basis of parameters in operation of units, but the drum-level height h indicated by the level-gauge with differential-pressure measuring method used at present for thermotechnic measuring and operation monitoring only after carrying out correction of drum-pressure can reflect a comparatively accurate real drum-level. For these, some expounded proofs are given by inference.
