3. Working Principle

The vortex flow meter measures flow based on the principle of “Kármán Vortex Street.” When the medium flows past a triangular bluff body at a certain velocity, alternating vortices are generated behind the body. These vortices create pressure pulsations, which are detected by a piezoelectric element in the sensor.

The frequency of the vortices (f) is proportional to the fluid velocity (V) and can be expressed as:
f = Sr × V / d
Where:

• f = Vortex frequency
• Sr = Strouhal number (~0.16 for stable flow)
• d = Width of the bluff body

By detecting the vortex frequency, the flow meter calculates the fluid flow rate, providing real-time measurements.
