Vortex flowmeters are also known as vortex flowmeters or Karman vortex flowmeters. Comprehensively absorbing the advanced technology of developed countries and summarizing the years of research and production experience, we have carefully designed the products to achieve product intelligence, standardization, serialization, generalization, production of mold, and ensure the quality of the product. This product has advanced circuit, low power consumption, wide range, simple structure, small resistance loss, sturdiness and durability, wide use, long service life, stable operation, easy installation and debugging. It is mainly used for the flow measurement of industrial pipeline medium fluids, such as gases, liquids, vapors and other media. Its characteristics are low pressure loss, large range, high precision, and almost no influence of parameters such as fluid density, pressure, temperature, and viscosity when measuring volume flow.
