为加强能源管理,提高计量精度,水蒸汽流量的温度压力自动补偿日益为人们所重视,国外目前已有为此用途的专用微处理器,国内有不少单位在研制自动补偿用单板机,有的已在实际中使用,但更多的是使用模拟仪表实现补偿。本文就收集到水蒸汽密度(重度)方程式进行分析比较,以供选用时参考。 In order to strengthen the energy management and improve the measurement accuracy, automatic compensation of temperature and pressure of steam flow is paid more and more attention by people. There are some special microprocessors for this purpose in the world. Many domestic units are developing single- Some have been in actual use, but more is the use of analog instrumentation to achieve compensation. In this paper, the collected water vapor density (severe) equation for analysis and comparison, for the selection of reference.
