About AGA-3 Orifice
AGA-3 Orifice calculates size, flow-rate or pressure drop for gas and liquid flow orifice meters based on the American Gas Association AGA Report No. 3 (AGA-3) (also API Manual of Petroleum Measurement Standards, Chapter 14.3). Orifice Size is calculated from given flowrate and pressure drop, Flowrate is calculated from given size and pressure drop and Pressure Drop requires orifice size and flowrate.
Different taps can be selected: Flange Taps and Pipe Taps.
Fluids include gases: Natural Gas (Specific Gravity must be provided), Air and Nitrogen, or liquids: Crude Oil, Water, Methanol, Mono-ethylene Glycol, Diethylene Glycol and Triethylene Glycol.
In addition, selecting orifice material will adjust the sizing parameter of the orifice depending on temperature.
Customary or SI-units.
