The conservative KOBOLD Vortex stream meter Type DVZ is utilized for measuring and observing the compact and medium-sized flows of low consistency, water-like fluids in funnels. The gadget utilizes the vortex rule, making it maintenance-free. It accomplishes high linearity over the entire measuring extent. The stream volume can be resolved with a comprehensive level of correctness by measuring the vortex recurrence. This includes the installation of a sharp-edged object in the flow duct. Vortexes are made behind the article whose recurrence rates correspond to the speeds of the flow of the fluid.
