Flow damping 
Navigation  Expert → Sensor → Process param. → Flow damping (6661)
Description Use this function to enter flow damping. Reduction of the variability of the flow measured
value (in relation to interference). For this purpose, the depth of the flow filter is adjusted:
when the filter setting increases, the reaction time of the device also increases.
User entry 0 to 15
Factory setting 4
Additional information User entry
• Value = 0: no damping
• Value > 0: damping is increased
• 0 is a weak damping and 15 a strong one.
• A damping of 0 is not recommended, as the measuring signal is then so noisy that it
is almost impossible to carry out a measurement.
• The damping depends on the measuring period and the filter type selected.
• An increase or decrease in the damping depends on the application.
Effect
The damping affects the following variables of the device:
• Outputs →  104
• Low flow cut off →  76
• Totalizers →  167
Flow override 
Navigation  Expert → Sensor → Process param. → Flow override (1839)
Description Use this function to select whether to interrupt the evaluation of measured values. This is
useful for the cleaning processes of a pipeline, for example.
Selection • Off
• On
Factory setting Off
Additional information Description
Flow override is active
• The diagnostic message diagnostic message C453 Flow override is displayed.
• Output values
– Temperature: proceeding output
– Totalizers 1-3: Stop being totalized
Positive zero return can also be enabled via the Status input: Assign stat.inp.
parameter (→  103).
