How Vortex Flowmeters Work

In 16th century Italy, Leonardo da Vinci observed how vortices form in flowing water. Some 400 years later, Hungarian physicist Theodore von Karmen described the physical laws for how these vortices take shape. Today, vortex flowmeters based on the "Vortex Principle" are used to measure liquids flowing through piping systems. This video explains how vortex flowmeters work.
