JC-080 series smart vortex flowmeter is mainly used for measuring the flow of industrial pipeline fluid, such as gas, liquid, and steam, etc.
It has little pressure loss, a broad span range, and high accuracy. It is not under influence of density, pressure, temperature, and viscosity when measuring volumetric flow. It has no movable mechanical parts with high reliability and little maintenance.
Setting vortex generation body (bluff body) in fluid, regular vortex will alternately generate from two sides of vortex generation body. This kind of vortex is called the Karman vortex. See picture 1. Vortex is downstream of vortex generation body, unsymmetrical array. Set occurrence to be f, the average flow speed of measured medium U, face width d, and diameter D. According to Karman principle, existing following relation :
f = StU1/d = Stu/MD
U1 – average flow speed at two sides of vortex generation body, m/s
St – Strouhal number
m – the ratio of segment area and pipeline cross-sectional area
Instantaneous volumetric flow :
In the formula K — Instrument Coefficient, pulse number/m3 (P/m3)
K has relation with vortex generation body, pipeline dimension, and Strouhal number. Strouhal number is a parameter without dimension. It has something to do with the shape of the vortex generation body and Reynolds number. Seeing from the picture, in the range of Re = 2 * 104 ~ 7 * 106, St can be seen to be a constant. When measuring gas flow, the flow calculation formula of JC-080 is
