由于节能和经济核算的需要,目前有些厂家正在试制供测量蒸汽流量的专用流量计。这种流量计具有压力定值补偿或自动补偿,能很好的克服蒸汽压力变化产生的误差,对提高计量精度有着重要的意义,是一种比较理想的蒸汽计量仪表。但是,蒸汽流量计的标定是较为困难的。本文介绍的一种标定蒸汽流量计的方法,可供生产蒸汽流量计的单位及有关人员参考。
Due to the needs of energy conservation and economic accounting, some manufacturers are currently trying out a special flowmeter for measuring steam flow. This kind of flowmeter has pressure setting compensation or automatic compensation, which can well overcome the error caused by the change of steam pressure, which is of great significance to improve the measurement accuracy. It is an ideal steam measuring instrument. However, the calibration of steam flowmeter is more difficult. This article describes a calibration method of steam flow meter, steam steam flow meter for the production of units and the relevant personnel.
