Dynamic variables Measured variables
(HART device variables)
Primary dynamic variable (PV) Volume flow
Secondary dynamic variable (SV) Temperature
Tertiary dynamic variable (TV) Totalizer 1
Quaternary dynamic variable (QV) Totalizer 2
The assignment of the measured variables to the dynamic variables can be modified and
assigned as desired via local operation and the operating tool using the following
parameters:
• Expert → Communication → HART output → Output → Assign PV
• Expert → Communication → HART output → Output → Assign SV
• Expert → Communication → HART output → Output → Assign TV
• Expert → Communication → HART output → Output → Assign QV
The following measured variables can be assigned to the dynamic variables:
Measured variables for PV (primary dynamic variable)
• Off
• Volume flow
• Corrected volume flow
• Mass flow
• Flow velocity
• Temperature
• Pressure
• Calculated saturated steam pressure
• Total mass flow
• Energy flow
• Heat flow difference
Measured variables for SV, TV, QV (secondary, tertiary and quaternary dynamic
variable)
• Volume flow
• Corrected volume flow
• Mass flow
• Flow velocity
• Temperature
• Calculated saturated steam pressure
• Total mass flow
• Energy flow
• Heat flow difference
• Condensate mass flow
• Reynolds number
• Totalizer 1…3
• HART input
• Density
• Pressure
• Specific volume
• Degrees of superheat
Device variables
The device variables are permanently assigned. A maximum of 8 device variables can be
transmitted:
• 0 = volume flow
• 1 = corrected volume flow
• 2 = Mass flow
• 3 = flow velocity
• 4 = temperature
• 5 = calculated saturated steam pressure
