流量计的工作范围较宽,在线实流检定过程中,需要对不同的流量点进行检定,由于现场流态条件较为复杂,流量调节完成后很难达到压力完全平衡,调流位置的不同,会导致流量点调节完成后被检表至标准表管段压力波动的变化趋势不同,相应的管容变化趋势也不同,对检定结果可能会有一定的影响,通过分析比较不同的调流位置对检定结果产生的影响,为以后的实流检定工作提供参考。
The flowmeter has a wide working range. During the online real flow verification process, different flow points need to be checked. Because the on-site flow conditions are complicated, it is difficult to achieve complete pressure balance after the flow adjustment is completed. Resulting in the flow point adjustment is completed to be seized standard gauge pipe section pressure fluctuations of the trend of change, the corresponding change in the trend of the tube is also different from the test results may have some impact on the analysis by comparing the different flow position of the test results The impact of the real flow for the future verification work to provide a reference.
