Product Description
HGVF series smart vortex flowmeter is mainly used for measuring flow of industrial pipeline fluid, such as gas, liquid and steam, etc. It has little pressure loss, broad span range and high accuracy. It is not under influence of density, pressure, temperature and viscocity when measuring volumetric flow. It has no movable mechanical parts with high reliability and little maintenance.
OPERATION PRINCIPLES
Setting vortex generation body (bluff body) in fluid, regular vortexs will alternately generate from two sides of vortex generation body. This kind of vortex is called Karman vortex. See picture 1. Vortex is at downstream of vortex generation body, unsymmetrical array. Set occurrence to be f, avarage flow speed of measured medium U, face width d and diameter D. According to Karman principle, exsiting following relation:
F = StU1/d = StU/md
U1 - avarage flow speed at two sides of vortex generation body, m/s
St - Strouhal number
M Ratio of segment area and pipeline cross sectional area
