Abstract
An experimental investigation of square-edged orifice meters built to ASME standards has shown that, in the pipe Reynolds Number range 20–2000, variations in discharge coefficient up to 6% can occur when the throat length to pipe diameter ratio is allowed to vary within the limits set by these standards, for a fixed value of the orifice to pipe diameter ratio, β, using corner taps. These variations are eliminated when the throat length to diameter ratio is kept constant, for a given value of β, even when the absolute diameters are allowed to vary.Keywords
