System Value -
Calc. Mass Flow
Read only The calculated mass flow appears on the display.
The calculated mass flow is calculated using the measured volume flow
and the value entered in the "Process Param. – Operating Density"
parameter (Page 94). A fixed value is used for the calculation
(specified operating density). For this reason only select this process
variable if the process conditions are known and do not change.
! Note!
The unit is displayed in the "System Unit - Calc. Mass Flow" parameter.
