Topics: Introduction Equations Discharge Coefficients Error Messages References. Introduction to Orifice Flow Meter Calculation. Orifice flow meters are used to determine a liquid or gas flow rate by measuring the differential pressure (P1 - P2) across the orifice plate. The two standard pressure tapping arrangements for small bore orifices are shown in the drawings; the location of the pressure taps affects the discharge coefficient somewhat.
Typically, the lateral may be a sub-manifold pipe. with orifices, in which case the discharge coefficient C L is calculated in the manner described above for an orifice type. pipe manifold. Hudson et al (1979) reviewed published data for entry head loss in dividing flow manifolds with square-edged laterals.
