Setting / Description
Select: Liquid / Steam / Gas / Wet Gas / Gas Mixture
Appropriate media can be selected in menu C1.2 dependent on selected fluid type.
If fluid = "Liquid":
Water / Custom
If fluid = "Steam":
Saturated Steam / Superheated Steam / Custom
If fluid is "Gas" or "Wet Gas" (for details refer to Gas options for gas measurement on
page 63)
This menu is available if fluid = "Wet Gas" or "Gas Mixture", or if medium = "Air" and
meter type = "Heat & Dens. & FAD".
Here the gas composition or gas properties can be defined.
This menu is available for fluid = "Gas Mixture".
Enter gas mixture as percentage share of gas options (for details refer to Gas options
for gas measurement on page 63)
This menu is available if fluid = "Wet Gas". Enter: 0...100%
The menus C1.3.3 to C1.3.9 are part of the FAD functionalities. They are available, if
fluid = "Gas", medium = "Air" and FAD functionality is included in the meter type option.
Enter ambient temperature of the compressor inlet side in selected temperature unit
(C6.5.19).
Enter ambient pressure of the compressor inlet side as value in selected pressure unit
(C6.5.17).
Enter pressure drop of compressor filter in selected pressure unit (C6.5.17).
Enter relative air humidity of the compressor inlet side as 0...100%.
Enter relative air humidity of the compressor outlet side as 0...100%.
Enter compressor revolutions per minute.
Enter rated compressor revolutions per minute.
This menu is available, if fluid = "Steam" and medium = "Saturated Steam".
Enter 0.85...1
The current input is a passive 2-wire 4...20 mA input. An external power supply is
required (for details refer to Current input on page 46).
Select "On" or "Off" to enable or disable the current input.
If current input function (C1.5.1) = "On", the following selection is available:
Pressure External / Temperature External
0% value = 4 mA for pressure value or temperature value
100% value = 20 mA for pressure value or temperature value
Select: Not available / Internal / External / External HART / Sat. Steam Temp.
(Saturated steam temperature only available for meter types "Heat & Dens. by Pres."
and "Heat & Dens. & FAD")
Temperature source 1 and 2 must be different.
If the current input is set to "Temperature External", either "Temp. Source1" or "Temp.
Source2" may be set to "External". If the current input is set "Pressure External", the
"External" option is not available to both temperature source 1 and 2.
Select: Not Available / Internal / External / External HART
(Pressure sensor support only available for meter types "Heat & Dens. by Pres." and
"Heat & Dens. & FAD")
Enter: 0...100 s
Sets low flow values to "0". Enter value for low flow cutoff in volumetric flow unit.
