Local values: Uses Local Values of gas components.
Remote values: Uses the block's Remote Values (input pin values from an online
analyzer).
Under certain situations, the gas component values may exceed the expanded range
recommended by the AGA 8 Report. In Override mode a flow rate will be calculated. It
should be noted that calculated flow rates for conditions where the expanded range is
exceeded are outside of the recommended uncertainty values for AGA 8 calculations.
Method 1 calculates the super-compressibility and gas density from knowledge of the
relative density, heating value and carbon dioxide, hydrogen and carbon monoxide
components.
Method 2 calculates the super-compressibility and gas density from knowledge of the
relative density, Nitrogen, carbon dioxide, hydrogen and carbon monoxide
components.
