Operating mode / Description

Standard volume flow
Gas Std/Norm Vol. /
NG2
Gas Mass (reference Gas mass flow, calculated using
density) / NG3 the reference density
Gas Mass (actual Gas mass flow, calculated using
density) / NG3 the actual density
2) The highest priority of the device is to record the density via the analog input, as long as the analog input is activated as a density input. If the analog input is not
available as a density input, the system attempts to record the density via the HART input. If both the analog input and the HART input are deactivated as a density
input, the system uses the default density value.
3) The connection via the analog input or HART input is described in the chapter titled „Electrical connections" on page 21.
5) The highest priority of the device is to record the temperature via the analog input, as long as the analog input is activated as a temperature input. If the analog input is
not available as a temperature input, the system attempts to record the temperature via the HART input. If both the analog input and the HART input are deactivated
as a temperature input, the system uses the default density value.
7) If the selection "Gas linear." is set for the menu item Device Setup / Plant/Customized -> Gas Std. Mode, the compression factor is reset to 1.0. See also the chapter
titled "Special operating modes" in the operating instruction.
