Deactivating the damping of the volume flow rate values
By default, the volume flow rate values are not damped.
But if the damping of the volume flow rate values is active, do the following to deactivate it:
→
Select the device in the navigation area.

Finish
The damping of the volume flow rate values is inactive.
13.4.5
Activating the monitoring of the volume flow rate
Because of a malfunction in the process or in the flow rate sensor, the measured flow rate value can be too
high or too low.
A monitored value can be:
•
in the normal operating range
•
in the warning range
•
in the error range
You can set 4 limit values: 2 error limits and 2 warning limits.
→
To set the limit values, see chpt.
13.4.7 Changing the error limits, the warning limits and the hysteresis of
.
explains how the device reacts when the monitored value enters in another range (for example,
from the normal range into the warning range). The reaction time depends on the hysteresis value and
whether the monitored value increases or decreases.
