| 摘要: |
| 采用双节流元件组合的方式,建立了基于Murdock系数的流量测量的数学模型,在此基础上研制开发了一种新 型的基于双槽式孔板节流元件的流量计,并用流量计样机对空气和水组成的两相流进行了测试试验。结果表明,气 相流量测量的相对误差绝对值平均在10%以内，液相流量测童的相对误差平均在30%以内，验证了该流量计可以在 一定范围内对气液两相流进行在线计量。 |

| Abstract: |
| By using dual orifice plate, a mathematical model based on Murdock coefficient was established for flow measuring. And then a new flowmeter by dual slotted orifice plate was developed. A series of experiments of air-water two-phase flow were implemented with model machine of flowmeter. Hie results show that the relative error of gas-phase flow averages within 10%，and that of liquid-phase flow averages within 30%. The results proves that this flowmeter can be used to measure two-phase flow online within certain scope. |
