11.6.6
Every level/distance measurement is stored internally in a buffer for filtering. This setting defines the
length of the time window of which the data are stored in the buffer. If the buffer is full, the oldest
value is replaced by the most recent one.
The figure below illustrates the default moving filter duration of 180 seconds. While a
of 90 seconds embraces two measurement values, an interval of 45 seconds includes 4 val-
ues.

The level/distance values in the buffer can be filtered by one of the following options:
