  • Page 4: Operating Principle

    5. Operating Principle The compact KOBOLD Vortex flow meter, model DVZ, is used for measuring and monitoring smaller and medium-sized flow of low viscosity, water-like fluids in pipes. The device works using the vortex process, making it virtually maintenance-free. This involves the installation of a sharp-edged object (the vortex generator) in the flow duct.
