Vortex Flow Meter
The vortex flowmeter 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.
These vortices are called Karman vortices, and the vortex rows are arranged asymmetrically downstream of the vortex generator. Vortex is produced according to this principle. The vortex is generated by the generating body, and the high-sensitivity sensor detects the number of vortices.
