The vortex flowmeter is a volumetric flowmeter that measures the volumetric flow of gases, vapors, or liquids, nominal volume flow, or mass flow produced according to the Karman vortex street principle. It is mainly used for the flow measurement of medium fluids in industrial pipelines, such as gas, liquid, steam and other media.
It is characterized by low pressure loss, large measuring range, high accuracy, and almost no influence of parameters such as fluid density, pressure, temperature, and viscosity when measuring volume flow. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable over a long period of time. The vortex flowmeter uses a piezo-electric stress sensor, which has high reliability and can work in the operating temperature range of -20°C to +250°C. There are analog standard signals and digital pulse signals output. It is easy to use with digital systems such as computers. It is a relatively advanced and ideal measuring instrument.
