Description
Define a mass flow factor for the
custom units. The factor is
based on SI mass flow units kg/
s
Define the decimal point for the
process value displayed in the
Local User Interface.
Set flow limit for low flow cut-off.
Below limit flow output is forced
to zero.
Set upper alarm limit. Alarm is
triggered if volume flow value is
above the limit.
Set upper warning limit. Warning
is triggered if volume flow value
is above the limit.
Set lower warning limit. Warning
is triggered if volume flow value
is below the limit.
Set lower alarm limit. Alarm is
triggered if volume flow value is
below the limit.
Sets the hysteresis for alarm
and warning limits. The hystere‐
sis is the distance between the
limits for activation and deactiva‐
tion of an alarm/warning.
