KARMAN VORTEX — VELOCITY FLOW METER

Vortex Velocity Flow Meter

Vortices form. The rate follows.

Vortex flow meters operate on the von Karman effect, built around a bluff body. As fluid flows past it, alternating vortices form behind the bluff body — detected by a sensor, with the frequency of their formation directly proportional to fluid velocity, letting the meter accurately calculate flow rate.
