Orifice plate flowmeter flow calculation algorithm

Thread Content

Currently, when calculating the orifice diameter for orifice plate flow meters, according to the H G/T20570 method, the formula is Q=128.45*C*d0*d0*SQRT(ΔP/γ); while another formula used is Q=0.00399*C*d0*d0*SQRT(ΔP/ρ)； With the same parameters, the d0 values calculated by these two formulas are different; which calculation formula should be used then? Thank you

The calculation formula provided by the flow meter manufacturer shall prevail
