目前,直接测量气体质量流量的机械式仪表很缺少,特别是用于质量小于100kg/h的小流量仪表更缺少。本文介绍的方法是以管道内介质流动速度调制为基础的,利用受质量流量阻尼的机械振荡器。图7幅
At present, there is a lack of mechanical instruments that directly measure gas mass flow, especially for small flow meters with mass less than 100 kg / h. The method described in this paper is based on the modulation of the flow rate of a medium in a pipe using a mechanical oscillator damped by mass flow. Figure 7 Figure
