Input of the damping factor
Each displayed measured value is a floating average of the last x seconds, with x being the damping factor. If 0 s is
entered as damping factor, no average is calculated.
The value of 10 s is appropriate for normal flow conditions. If the values fluctuate strongly, caused by a higher dynamic
flow, a higher damping factor can be very useful.
• Enter the damping factor.
