饱和蒸汽是应用最广泛的二次能源之一,因此饱和蒸汽的设计量越来越受到关注,如果能够精确地计量和科学的管理,对节能工作无疑具有十分重要的意义。在过去较长的一段时间里,饱和蒸汽的计量普遍采用无补偿功能的仪表。这种仪表的设计参数与实际工况参数往往有一定差异,特别是在蒸汽压力波动较大的场合,计量偏差更大,甚至大到不能允许的程度,给计量管理工 Saturated steam is one of the most widely used secondary energy sources. Therefore, the design volume of saturated steam is getting more and more attention. If accurate measurement and scientific management are available, it is of great significance to energy conservation. In the past, for a long period of time, the measurement of saturated steam has generally adopted instruments without compensation functions. There are certain differences between the design parameters of these instruments and the actual working conditions. Especially in the occasions where the steam pressure fluctuates greatly, the measurement deviation is even greater, even to a degree that cannot be tolerated.
