Product Description

The vortex flow meter produces a velocity flow meter based on the Karman vortex principle for measurement and metering of conventional gases, vapors and liquids. The vortex flow sensor has high precision and a wide range ratio. It has no moving parts in use, which can improve mechanical stability and reduce maintenance. Vortex is almost unaffected by the temperature, pressure and composition of the medium when measuring the working volume, so it is convenient for the calibration production of the instrument. Therefore, the vortex flow sensor is widely used in production and life.
