  • Contrec 515 Series with GN11 application measures the volume, mass and gross heat content of natural gas. The instrument uses a frequency volume flow input and analogue temperature and pressure sensor inputs.

    The instrument is compatible with a wide range of flowmeter frequency outputs. Millivolt signals, reed switches, Namur proximity switches or pulse trains can be selected via its smart front-panel programming.

    The SGERG calculation (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
