XGHLUGB Flowmeter with Vortex-Shedding Principle:

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 their relationship with flow. As shown in Figure 1, a triangular body, which is the vortex generator, is vertically inserted into the casing. When a medium flows through the casing, regular Karman vortices with opposite directions are alternately generated 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 rate of the medium being measured can be determined based on the casing diameter.
