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%.

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.
