Vortex flowmeter kvf200  is designed and manufactured according to Carmen vortex principle. The flow measurement based on the principle of fluid oscillating vortex is mainly used for the flow measurement of two fluids in industrial pipeline, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large range and high precision. When measuring the volumetric flow under working conditions, it is almost not affected by the parameters such as fluid density, pressure, temperature and viscosity.
