MENU 3 - MEASURE
(POS. 3.1) Damping [Damping=OFF/SMARTX /(time)]
This section of the manual is extremely important. The correct filter settings ensures a proper
response of the instrument to the measured flow rate. The available dampening filter values range
between no damping (damping=OFF) and maximum damping based of 1000 seconds
(Damping=1000).
The three diagrams below demonstrate the instrument behavior with different dampening settings
with flow rate changes in the range of 1-100%.

Damping function(OFF).
the meter follows the
trend of fast changes in
flow
Damping (Smart 1,2,4):these
settings effect a predefined
filter dampening of the noise
and sudden change in flow
rate on the rise.
Damping mode based on
time (fro
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.
