Overview: The LUGB series vortex flowmeter is based on the Carmen vortex street principle for flow measurement. It is mainly used for the flow measurement of industrial pipeline medium fluid, such as the influence of parameters such as gas, temperature, viscosity, etc. No moving mechanical parts, so high reliability and low maintenance.
Working principle: When the fluid flows through the vortex flowmeter sensor in the pipeline, two rows of vortexes proportional to the flow rate are alternately generated up and down behind the vortex generator of the triangular column. The vortex release frequency and the average velocity of the fluid flowing through the vortex generator and the vortex occurrence Body width is related.
