f=StV/d I Factor: f-The Karman vortex street frequency which one side of vortex-maker St-Strouhal number(dimensionless number) V-mean flow rate d-the width of vortex-maker So, check the separate frequency of Karman vortex street to know the instant capacity(flow) .among, Strouhal number(St)is dimensionless number, Chart II Show the relation of, Strouhal number(St) & Reynolds number (Re) Straightness part in curve(St=0.17),free frequency & flow rate of vortex is direct ratio, it means flow sensor range. so just check out frequency (f),we can get the flow rate inside pipe, then as the flow rate(V) to take volume flow, the ratio record of impulse & volume, called as(K),as follow(2) K=N/Q(1/m³) (2) Model:K=instrument constant(1/m³). N=impulse number Q=volume flow(m³) Contact us if you need more details on High Pressure for Steam Flow Meter.
