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.
In fluid dynamics and hygrometry, the volumetric flow rate is the volume of fluid which passes through a given surface per unit time. As defined by Darcy's law, volumetric flow rate should not be confused with volumetric flux. Volumetric flux is represented by the symbol q and its SI units are m 3 /(m 2.s) or m/s. The volumetric flow rate is given by the integration of a flux over an area. When the fluid flows in an angle Î¸, the volumetric flow rate Q can be calculated as:
