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.
stream function Ï displaystyle psi is constant on any streamline for the continuous flow the flow around any path is equal to zero for two incompressible flow patterns the algebraic sum of the stream functions is equal to another stream function obtained if the two flow patterns are super imposed the rate of change of stream function with distance is directly proportional to the velocity component perpendicular to the direction of change
