Working Principle
The LUGB type vortex flowmeter is a flowmeter designed and manufactured using the Karman principle theory of the relationship between the generation of vortices and the flow rate. It can be used to measure the flow of steam, gas and low viscosity liquids. A triangular column (vortex) generating body is inserted into the fluid, and a regular Karman vortex is formed alternately behind the triangular prism, and the separation frequency of the scoring is proportional to the flow velocity(V) of the measured medium. Therefore, the flow rate of the measured fluid can be calculated by detecting the number of vortices by the flow meter sensor head, and the signal processing circuit calculates the volume flow rate of the measured medium according to the sensor aperture.
