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.
The high pressure water is forced. through an orifice to create a high velocity waterjet, the cutting beam. Typical abrasive waterjet (AWJ) cutting heads consist of these components; nozzle body. (upstream UHP water tube), orifice, orifice mount, abrasive mixing chamber and mixing. tube.
