Mass particle has oscillation velocity v1 , has to be accelerated to higher oscillation velocity v2 质量团的不可压缩特性，使得被加速时对管壁产生压力。
Because mass particle is inert, it presses against the pipe wall when being accelerated. 管壁上的压力将减缓管道的运动。
The pressure against the pipe wall slows down the pipe movement. 管道出口：同样的效应将加速管道的运动 Outlet piping: The same effect accelerates the pipe movement.FC010BPEA质量流量计的测量信号 Mass flow measuring signal A, B = 传感器位置 A, B = sensor location y = 管道在A, B 的运动 y = pipe movement at A, B t = 时间 t = time = 相位偏移 = phase shift (= time shift between pipe movement at A, B) 质量越大，相位偏移越大 The larger the mass, the higher the phase shift. 流速越快，相位偏移越大 The faster the mass, the higher the phase shift.~ m*v = mClassification: Advanced Customer training 01/08/2010 Li jugang Slide 8.FC010BPEA传感器的一般论述Coriolis sensor (general remarks)关于科氏力传感器的一般论述 Some general remarks concerning all Coriolis sensors:双管设计/单管设计 Dual-tube design / single-tube design双测量管是本质上平衡，相互补偿，有效抵抗外界的影响。
Dual-tube instruments are intrinsically balanced against external disturbances because the tube movements compensate each other. E+H的单直管采用了专利的平衡技术。
Endress+Hauser puts extra effort into the design of single-tube instruments. With competitor’s single-tube instruments, vibration immunity is often a weak point.材质选择 Material choice不锈钢材质有相对较大的热膨胀系数。
因此测量100 ºC上介质时，测量管 必须设计成弯曲以卸除温度提高所造成的膨胀应力。
