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.
Comparing the vortex shedding flowmeter to an orifice plate the former has higher accuracy and rangeability, does not. require complex pressure impulse lines, is less sensitive to wear and, for volumetric flow measurement, does not require the need to. compensate for fluid density. Industrial vortex shedding flowmeters are normally available in pipe sizes ranging from Â½â to 12â, with some manufacturers offering. sizes up to 16â.
