Automatic change of the measuring range
Two different working ranges allow variable
adaptation to different process conditions.
It must be ensured that Scale end value 2
FS2
is greater than Scale end value 1
FS1
.
When the flow rate increases and reaches
100% of Scale end value 1
FS1
, the system
automatically switches to
Scale end value 2
FS2
.
When the flow rate decreases and the
Scale end value 2
FS2
reaches a value equiva-
lent to 90 % of Scale end value 1
FS1
, the
system automatically switches to
Scale end value 1
FS1
.
This feature does not increase the accuracy of
the measurement.
The goal is to increase the 4/20 mA resolution
when the sensor measures at very low flow
rates.

The choice of damping filter, depending on the system require-
ments, is crucial for the accurate measurement of flow rate.
The selection
SMART
is the recommended setting for the damping
of the measured values.
With this adaptive damping filter, the sensor can respond very
quickly to changes in flow, while being precise and stable with slow
fluctuations in flow.
With inactive damping
OFF
, successive values cause an increasing
damping of the measured values.
