Abstract: The orifice meter formula might be more properly called the head meter formula, since the same basic equation applies-regardless of whether the restriction in the line, which generates the increase in velocity, is an orifice, nozzle or Venturi tube. This equation, basically, would apply in an open stream flow where we would measure the head induced by the velocity-as with a Pitot tube. Actually the Pitot tube. Figure 1, was used in commercial gas measurements in this country, before the orifice meter came into general use. While all of these flow measuring devices employ the same basic equation, there are pfeculiar characteristics, too difficult to determine theoretically, which must be determined by experiment and lumped into a dimensionless constant, K, called the coefficient of discharge.
