GPE F4001-Smart Vortex Flowmeter (also called a Vortex Shedding Flowmeter) is a versatile instrument that calculates the mass flow, volumetric flow rate, temperature, and pressure and density of any liquid, gas, or steam through a pipeline. Wide spread application is found in several industries including Petrochemical, Chemical, Pharmaceutical, Food and Beverage, Water, and Wastewater Treatment

Karman Vortex Street

This flowmeter operates on the principle of Karman Vortex Street, any medium passing through the pipeline flows around the bluff body and sheds a series of alternating vortices on each side of the body. This phenome- non is referred to as Vortex Shedding. These vortices shed downstream of the bluff body and dissipate as they flow further. This pattern of vortices is called a Karman Vortex Street (also called a Von Karman Vortex Street, see pictures in right side Fig. 1.1 ).
