Vortex flow meter for liquid and gas
https://www.leestransmitter.com/products/vortex-flowmeter/

A vortex flow meter is a type of volumetric flow meter that makes use of a natural phenomenon that occurs when a liquid flows around a bluff object. Vortex flow meters operate under the vortex shedding principle, where vortices (or eddies) are shed alternately downstream of the object. The frequency of the vortex shedding is directly proportional to the velocity of the liquid flowing through the vortex flow meter for liquid and gas.
