The intelligent vortex flowmeter is a high-precision volumetric flowmeter based on the Kármán vortex street principle, designed to measure the volumetric flow rate, standard volumetric flow rate, or mass flow rate of gases, steam, and liquids. This advanced flowmeter offers high reliability and minimal maintenance, as it is unaffected by changes in fluid density, pressure, temperature, or viscosity. Built to meet JB/T9249-1999 and JJG1029-2007 standards, it ensures long-term stability and accuracy, making it ideal for industrial flow measurement applications.
