Abstract In many fluid flow applications, mass flow rate is preferred over volume flow rate, as it is more beneficial in terms of cost and material balance calculations. Coriolis mass flow meter (CMFM) is accepted widely for mass flow measurement owing to its accuracy and reliability. However, it has been found to under-read the mass flow rate in laminar flow region [1], thus limiting its application in this region. The secondary flow in the curved tube section influences the generated Coriolis force and leads to a deviation in meter readings. Commercial CMFMs are available with various curved tube configurations and need to be analyzed for their application in laminar region. This paper presents comprehensive experimental and numerical investigations performed to evaluate the influence of tube configuration and other meter parameters, such as drive frequency, amplitude of vibration, and sensor position, on the performance of the CMFM in laminar region. The findings of this study have put forth a suitable combination of tube configuration, drive frequency, and sensor position while using the CMFM in laminar flow regime.

科里奥利质量流量计在层流状态下的性能评估

摘要 在许多流体流动应用中，质量流量比体积流量更受欢迎，因为它在成本和材料平衡计算方面更有利。科里奥利质量流量计 (CMFM) 由于其准确性和可靠性而被广泛用于质量流量测量。然而，已经发现在层流区域 [1] 中的质量流量读数不足，从而限制了其在该区域的应用。弯管段中的二次流会影响产生的科里奥利力并导致仪表读数出现偏差。商业 CMFM 可用于各种弯管配置，需要对其在层流区域的应用进行分析。本文介绍了为评估管配置和其他仪表参数的影响而进行的综合实验和数值研究，例如驱动频率、振动幅度和传感器位置，对 CMFM 在层流区域的性能。本研究的结果提出了在层流状态下使用 CMFM 时管配置、驱动频率和传感器位置的合适组合。
