XGHLUGB Turbulence Street Flow Meter:

The XGHLUGB type vortex flow sensor measures the flow of steam, gases, and low-viscosity liquids based on the theories of Karman and Strouhal regarding the generation of vortices and the relationship between vortices and flow rate. As shown in Figure 1, a triangular body is vertically inserted into the casing to act as a vortex generator. When a medium flows through the casing, alternating, regular, and opposite-direction Karman vortices are produced behind the triangular column. The separation frequency F of the vortices is proportional to the flow velocity V of the medium. By detecting the number of vortices with the sensor head, the fluid velocity can be calculated, and then the volume flow of the measured medium can be determined based on the casing diameter.
