Coriolis mass flowmeter based on torsional acceleration amplitude

The invention discloses a Coriolis mass flowmeter based on torsional acceleration amplitude, and belongs to the technical field of mass flow mechanical measurement. The problem that the post-processing process of mass flow calculation of a traditional Coriolis mass flow meter is complex is solved. According to an amplitude ax0 of an acceleration signal in the x direction collected by an MEMS accelerometer, zero point correction is carried out on the amplitude ax0, and the mass flow qm of the fluid is obtained according to the corrected amplitude ax0. The invention is mainly used for mass flow measurement. 基于扭转加速度幅值的科氏质量流量计，属于质量流量机械测量技术领域。本发明解决了传统的科式质量流量计计算质量流量的后处理过程复杂的问题。本发明根据MEMS加速度计采集的x方向的加速度信号的幅值ax0，并对其幅值ax0进行零点修正，根据修正的幅值ax0得到流体的质量流量qm。本发明主要用于质量流量测量。
