1.1工作原理：当一个位于以P点为旋转中心做旋转运动的管子内的质点做朝向或远离旋转中心的运动时，将产生一贯性力，原理如图1:图1图中质量为δm的质点以匀速v围绕一个固定点P并以角速度ω旋转的管道内移动时，这个质点将获得两个加速度分量：1.法向加速度αr（向心加速度），其量值值等于ω2r，方向朝向P点；2.切向加速度αt（科里奥利加速度），其量值等于2ωv，方向与αr垂直。

TGF450流量计的测量元件由两个铂电阻传感元件和一个加热元件构成（如图1.1），它们被置于流体中。
测量时，一个传感元件由加热功率为Ｐ的加热元件进行加热，使其温度升至Ｔ1；另一传感元件不被加热，以用于测量介质温度，设为Ｔ2，因此两个传感元件之间将产生温差△Ｔ=Ｔ1－Ｔ2。
当流量为零时，△Ｔ最大，随着流量Ｑ的增大，传感元件的热量被带走，从而温度Ｔ1下降，则△Ｔ减小。
根据牛顿热力学定律，加热功率Ｐ、温差△Ｔ与质量流量Ｑ之间满足下式：Ｐ/△Ｔ＝Ｋ1＋Ｋ2*F(Q)K3上式中Ｋ1、Ｋ2、Ｋ3是与气体物理性质有关的参数, Ｐ为恒定加热功率，△Ｔ为传感元件的温差，F(Q)为质量流量与温差△Ｔ满足的函数关系式，Ｑ为质量流量。
