Adjusting the filter to the measured flow rate
This function enables you to dampen the following fluctuations in the transmission of measured values:
•
On the display
•
At the current output AO1
There are ten filters available. The following table lists the response times (10 to 90 %) for each filter:
NOTE!
If "fast" filtering has been selected and the flow rate changes by ±30 % (e.g., when switching the medium
circulation on or off), the filter is deactivated: The new flow rate is emitted in non-filtered form.
NOTE!
If the filter selected is too high, the device does not recognize jumps in the flow rate. This can lead to
large differences between the flow rate in the pipeline and the displayed flow rate or the value emitted
at the current output.
