| 中文摘要: |
| 涡轮流量计在安装和使用过程中往往存在直管段口径与流量计通径不完全一致的现象。选取CL系列和LWGY系列涡轮流量计，在燃油动态流量标准装置上进行了上下游直管段不同口径条件下的校准试验，从而得到直管段口径对涡轮流量计K系数的影响。试验证明，直管段口径所引入的误差不可忽视，因此在使用或校准涡轮流量计时应务必保证直管段口径与流量计通径一致。 |
| 英文摘要: |
| The diameter of straight pipe is not usually exactly the same with the diameter of turbine flow-meter, which effect the K-coefficient of the turbine flow-meter. By choosing CL series and LWGY series turbine flow-meter, the calibration test ,the impact of different diameters of upstream and downstream straight pipe, is carried out on the dynamic fuel flow standard device. The experimental results show that the error introduced from straight pipe can not be ignored, therefore, the use or calibration of turbine flow-meter is required diameter of straight pipe is consistent with the flow-meter. |
