Vortex flow meter is researched and produced according to Karman vortex flow principle. It is mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media.It is characterized by small pressure loss, large measuring range and high accuracy. It is almost free from the influence of fluid density, pressure, temperature, viscosity and other parameters when measuring the volume flow in working conditions.No moving mechanical parts, so high reliability, small maintenance.Instrument parameters can be stable for a long time.Vortex flow meter using piezoelectric stress sensor, high reliability, can be in -20℃ ~ +250℃ operating temperature range.It has analog standard signal and digital pulse signal output. It is easy to be used with computer and other digital systems. It is an ideal measuring instrument for comparison.

Vortex flowmeter is also called vortex flowmeter or Karman vortex flowmeter.Based on the comprehensive absorption of the technology of developed countries and the summary of many years of research and production experience, the products are elaborately designed to achieve intelligent, standardized, serialized, universal, mold-oriented production, and ensure the aesthetic quality of the products.The product has the characteristics of circuit, low power consumption, wide range ratio, simple structure, small resistance loss, durability, wide use, long service life, stable work, easy installation and debugging, etc.[1]?
