| 摘 要： | 分析了涡街流量传感器的旋涡作用力与流体密度的关系，得出流体密度与涡街作用力成正比，和流速的平方成反比。由于流速可以由涡街的频率测得，而测得涡街作用力后，即可根据此关系计算出流体的密度。

| Abstract: | The relationship between the fluid density and the force of vortex is studied.It is obtained that the fluid density is proportional to the force of vortex and inverse proportional to the squared velocity of the fluid.Since,the fluid velocity can be measured by the frequency of vortex signal,the fluid density can be obtained according to the presented formula if the vortex force is also measured. |
