Sekee Vortex flow meters operate based on the Karman effect, which involves the alternating formation of vortices on opposite faces of a bluff body placed in a turbulent flow of liquid, gas, or steam. This occurs because peripheral layers of the medium cannot follow the body's contours and separate from its surface. The sensor detects these vortices, while the electronic unit converts them into flow rate units.
Sekee Vortex flow meters offer high measurement accuracy for liquids, gases, and steam, high-temperature capability (medium temperature up to +450°C), reliability, long service life, and the ability to measure ultra-low flows (down to 2 m/s).
Vortex flow meters are available in two designs:
- inline type
- insertion type
