Vortex

 

isolv
The VORTEXFLO as a compact flowmeter in a flange version is suitable for universal use in measuring liquids, gases and vapours.
The temperature compensation for saturated steam is integrated as standard, thus enabling direct compensation of the density; the mass and energy can also be measured.

Measuring Principle


Vortex flowmeters are used to measure the volumetric flow of gases, vapours and liquids at completely filled pipes. The measuring principle is based on the Karman vortex street. The measuring tube contains a bluff body, behind which vortex shedding occurs. The frequency f of the vortex shedding is proportional to the flow rate v. The nondimensional Strouhal number S describes the relationship between vortex frequency f, width b of bluff body and the mean flow velocity v:
