Measurement principle

The product uses the Karman vortex street principle for measurement. When the fluid passes through the throttling device (such as the triangular metal cylinder in the vortex street), vortices will be generated alternately in the downstream direction. The number of vortices is proportional to the flow rate of the fluid. The pressure change generated by the vortex can be sensed by the sensor, forming an electrical pulse, thereby obtaining the flow rate data.

Main features
