摘要
简要地介绍了一种利用超声脉冲沿顺流、逆流方向传播速度之差来测定气体流速,进而测定流量的微机化超声波气体流量计的工作原理,以及针对南钢煤气流量测量的大管径、大量程比、介质波动频繁等问题提出了一种具体可行的解决方案。
The gas flow in a closed tube can be determined by measuring the difference between the downstream and upstream propagating velocity of ultrasound,the problem of big diameter of tube,large range of measure and fast change of gas medium about the measure of the gas flow are put forward.
