Flowmeters : Vortex Flowmeter
A flowmeter is an instrumentation device used to measure and record the flow rate of a gas or fluid. In a vortex flowmeter, a cylinder is placed in the flow. As the flow moves over the cylinder, it separates behind the cylinder and causes an oscillatory vibration. The vortex shedding occurs at a frequency known as the Strouhal shedding frequency and is directly related to the speed of the flow, thus allowing flow speed to be calculated from the cylinder vibration.
