Damping function (OFF). the meter follows
the trend of fast changes in flow.
Damping mode based on time (from 0.2s
to 1000s) The measure is averaged over
a number of samples determined by the
value assigned to the dampening function.
When the damping parameter is expressed
in seconds, the filter works damping the
measurement noise and sudden change
of flow rate. Increasing the parameter of
damping increases the stability of the
measurement.

This section of manual is extremely important because the correct setting of the filters allows to obtain a proper
response of the device to the measured flow rate and the specific requirements of use; as a general rule,
consider that, starting from Damping = OFF (no filter applied to the measure), successive values, introduce
increasing damping. The following diagrams show the device’s response to changes in flow rate from 0 to 100%,
using the different settings of the damping function.
The SMART is an adaptive filter that adapts automatically to most of the processes (recommended value),
making the response of the meter very ready to fast changes of flow and at the same time extremely precise
and stable for slow variations. It may be convenient to use a constant damping filter time, where there is a
pulsating flow (for example generated by peristaltic pumps). With longer times you get a mean value stable, while
with short times the measure will closely follow the flow pulses, but consequently more unstable. NOTE: If the
rechargeable battery is active, the damping could be set only in “SMART”.
