Witryna2 cze 2015 · The orifice flowmeter consists of a thin, flat plate sandwiched between flanges or installed in a dedicated fitting. The plate has a precise, sharp-edged orifice, bored concentric with the pipe axis. The flow pattern contracts as it approaches the orifice—the contraction continuing to a distance of approximately one orifice … Witryna9 lut 2024 · Equations used in this orifice plate Calculator Qv = 218.527*Cd*Ev*Y1* (d2 )* [Tb/Pb]* [ (Pf1*Zb*hw)/ (Gr*Zf1*Tf)]0.5 (3-6) Where Cd = Orifice plate coefficient of discharge d = Orifice plate bore diameter calculated at flowing temperature (Tf) – in.

Witryna12 cze 2016 · The diameter ratio or beta (sometimes referred to as the beta ratio) is the ratio between the diameter of the orifice or throat of device to that of the pipe. Often Δp meters are described in terms of their beta value and diameter to fit a certain pipeline size, for example, a 4-inch β= 0.6 Venturi tube.
