Vortex flow meters evaluate the vortices shed behind a bluff body in the measuring tube and have no moving parts.
The device measures steam, gas and liquids in DN25 … DN300 with ± 1.0 % up to +350 °C, output 4 … 20 mA or pulse. A compact vortex sensor with optional temperature measurement is listed under combined sensors, swirl meters for gas under gas.
