作为科里奥利效应的一个实际应用，科里奥利质量流量计的工作原理涉及诱发流体通过的流量管的振动。这种振动虽然不是完全圆形的，但它提供了旋转的参考坐标系，从而产生了科里奥利效应。虽然具体方法因流量计的设计而异，但传感器监测和分析振动流量管的频率、相移和振幅的变化。观察到的变化表示流体的质量流量和密度。质量和体积流量测量测量管被迫振荡，产生正弦波。在零流量时，两个管会同相振动。当引入流量时，科里奥利力会导致管道扭曲，从而导致相移。测量波之间的时间差，并与质量流量成正比。体积流量根据质量流量和密度测量值计算。观看此视频以了解科里奥利流量计如何测量质量流量和密度的更多信息（单击链接并选择查看视频

As a practical application of the Coriolis effect, the Coriolis mass flow meter operating principle involves inducing a vibration of the flow tube through which the fluid passes. The vibration, though it is not completely circular, provides the rotating reference frame which gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift, and amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid. Mass and volume flow measurement The measuring tubes are forced to oscillate producing a sine wave. At zero flow, the two tubes vibrate in phase with each other. When flow is introduced, the Coriolis forces cause the tubes to twist resulting in a phase shift. The time difference between the waves is measured and is directly proportional to the mass flow rate. Volume flow rate is calculated from mass flow rate and the density measurement.
