Process values
The process values are updated every 10 ms (100 Hz update rate) synchronous with the DSP
update cycle.
Process value parameters
The process values are:
● Mass flow
● Volume flow
● Standard volume flow
● Density
● Process media temperature
● Fraction A (mass flow or volume flow)
● Fraction B (mass flow or volume flow)
● Fraction A %
● Fraction B %
For SIL ordered flowmeters, mass flow, volume flow and density are available to be allocated
to the current output on Channel 1
For non SIL ordered flowmeters, all process values are available to be located to the current
output, Modbus RS485 and Profibus on Channel 1
For Channel 2 to 4 all all process variables are available
Limits and hysteresis
Limits
Limit alarms and warnings can be assigned to all process values. The following limit
parameters are available for each process value:
● Upper Limit Alarm
● Upper Limit Warning
● Lower Limit Warning
● Lower Limit Alarm
● Alarm Hysteresis
The system reports a process alarm when the process value exceeds the Upper Limit Alarm
or the Lower Limit Alarm. Likewise, the system reports a process warning when the process
