<- BACK TO FLOW METERS

FEATURES

• Once the Vortex has been inserted into the fluid, the instrument will generate a vortex on the two sides of the internal element. This type of vortex it is called Karman (see figure 1). The vortex is created asymmetrically downstream of the Vortex body. We indicate with "F" the average velocity of the fluid "U", the diameter of the Vortex with "d" and the diameter of the tube with "D". According to the principle of Karman, we have the following report: f = StU1 / d = StU / md U1: average flow velocity at the sides of the vortex generator, in m / s. St: Strouhal number m: ratio between the vortex generator area and the tube area.
