锅筒水位的正确测量

Correct Measurement of Drum Water Level

由于膨胀水位和冷缩水位的影响，水位计如何正确指示锅筒水位是锅炉安全运行的重要问题。通过理论分析和计算，以及对照试验数据，对水位计反映水位的真实性问题进行了讨论，可供锅炉设计和进行参考。

Abstract Because of the influence of expanding level and shrinking level, it becomes an important probleme of boiler safety operation whether the level indicator gives correct water level of the drum. Based on the theoretic analysis and calculation as well as comparison with the test data, this paper discusses the authenticity of water level indicated by the level indicator. It is worthful for boiler design and operation. Figs 2, tables 2 and refs 3.
