Function Setting / Description
C1 Process
C1.1 Fluid Select: Liquid / Steam / Gas / Wet Gas / Gas Mixture
Appropriate media can be selected in menu C1.2 dependent on selected fluid type.
C1.2 Medium 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)
C1.3 Gas 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.
C1.3.1 Gas Mixture 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)
C1.3.2 Relative Humidity This menu is available if fluid = "Wet Gas". Enter: 0…100%
C1.3.3 Inlet Temperature 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).
C1.3.4 Atm. Pressure Enter ambient pressure of the compressor inlet side as value in selected pressure unit
(C6.5.17).
C1.3.5 Filter Pressure Drop Enter pressure drop of compressor filter in selected pressure unit (C6.5.17).
C1.3.6 Inlet Rel. Humidity Enter relative air humidity of the compressor inlet side as 0…100%.
C1.3.7 Outlet Rel. Humidity Enter relative air humidity of the compressor outlet side as 0…100%.
C1.3.8 Compressor RPM Enter compressor revolutions per minute.
C1.3.9 Rated Compr. RPM Enter rated compressor revolutions per minute.
C1.4 Saturated Steam This menu is available, if fluid = "Steam" and medium = "Saturated Steam".
C1.4.1 Dry Factor Enter 0.85...1
C1.5 Current Input 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).
C1.5.1 Function Select "On" or "Off" to enable or disable the current input.
C1.5.2 Current Input Meas. If current input function (C1.5.1) = "On", the following selection is available:
Pressure External / Temperature External
C1.5.3 0% Range / 4mA 0% value = 4 mA for pressure value or temperature value
C1.5.4 100% Range / 20mA 100% value = 20 mA for pressure value or temperature value
C1.6 Temp. Sensor
C1.6.1 Temp. Source1 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.
So
urce2" 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.
C1.6.2 Temp. Source2
C1.7 Pressure Sensor
C1.7.1 Pressure Source Select: Not Available / Internal / External / External HART
(Pressure sensor support only available for meter types "Heat & Dens. by Pres." and
"Heat & Dens. & FAD")
C1.8 Time Constant Enter: 0...100 s
C1.9 Low Flow Cutoff Sets low flow values to "0". Enter value for low flow cutoff in volumetric flow unit.
