The pressurelosscoefficient is affect by the Re number smaller, basic is decreased with increasing Re.
压力损失系数受雷诺数的影响较小，基本是随着雷诺数的增大而减小的；
2
Using numerical simulation software, with setting different gas pressure in pipe, the pressurelosscoefficient of inner-cone flowmeter was simulated.
利用数值模拟软件，通过改变管道内气体的压力，对内锥流量传感器的压力损失系数进行模拟研究。
3
This changing regularity is studied and the equation which expresses the relation between the pressurelosscoefficient and gas pressure in pipe is given.
