基于流体振动原理的涡街流量计对振动干扰尤为敏感，为解决振动问题对涡街流量计发展的影响，通过实验证明了管道振动方向的多样性，同时基于涡街载荷方向的单一性提出了通过方向区分振动信号和涡街信号的新思路。为验证这一思路，将 MEMS 加速度计安装在探头末端，在振动条件下采集实验信号。实验结果证实：加速度计在3个方向上检测到了不同的信号，通过不同方向的加速度信号能够对涡街信号和振动信号进行有效区分。

The vortex flowmeter is sensitive to the vibration interference which boasting of directional diversity in pipelines.Considering unicity of the vortex loading direction,having the direction based to identify both vi-bration signal and vortex signal was proposed;and through equipping the probe with a MEMS accelerometer, the experimental signals were collected under the vibration conditions to show that,the accelerometer can de-tect various signals at three different directions which can effectively identifies vibration signals and vortex sig-nals.
