Natural Gas Flow Computer (SGERG) – DP Meter (Mass Span)
The 515-GN13 Natural Gas Flow Computer measures the volume, mass and gross heat content of natural gas. The instrument uses single or stacked differential pressure mass flow inputs and analog temperature and pressure sensor inputs.
The GN13 Natural Gas Flow Computer calculates the flow according to generic differential pressure equations and incorporates the conditions at which the flowmeter was calibrated.
The AGA-8 Detail Characterization Method is used to obtain accurate values of density and compressibility factors for the flow calculations.
Calculations
The gas density and compressibility factor calculations are based on the SGERG (AGA-8 Gross) equations. The calculations are valid for the region:
• -8.0°C < t < 62.0°C P < 12MPa
• 17°F < t < 143.0°F P < 1740psia
Formulas:
• Mflow = volume flow• ρflow
• corrected flow = Mflow/ρ ref
• Heat flow = Mflow•Hm
Where:
• Mflow = mass flow
• ρflow = density at flow conditions
• ρ ref = density at reference conditions
• Hm = mass gross heating value
