摘要:
介绍了小流量气体流量测量装置的原理和应用背景，建立了小流量气体测量系 统。采用两种实验方法，即质量流量计串连孔板测量法和孔板配合差压测量法，进行了测量， 得到小流量拟合公式。比较了不同实验方法的精度和特点。结果表明，第二种方法重复性好， 测量精度高。
Abstract:
New approch to the control and measurement of small gaseous nlass flow rate is needed when the mass flow rate is too small to be measured by traditional flow meter．In this paper， the background and principle of the instrumentation system for small gaseous mass flow rate measurement are presented．The instrumentation system were set up．Two means，namely，the small mass flow rate measurement by tandem arranged orifice plate and mass flow rate meter，and small mass flow rate measurement with orifice plate and differential pressure were tested．Different fitting equations were obtained．The accuracy and characteristics of the two methods were also compared．The results show that the second method has reasonable repeatability and the accuracy has improved effeetively．
