Vortex Flow Meters
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Vortex flow meters are instruments used to measure the flow rate of liquids and gases. They operate based on the principle of vortex shedding, where alternating vortices are generated as fluid passes around a bluff body placed in the flow stream. The frequency of vortex shedding is proportional to the flow velocity, allowing for accurate flow measurement across a wide range of applications.
