The "Signal Dampening" tab deals with the way in which the flowmeter reading responds to changes in flow. Unfiltered fully developed turbulent flow, as it exists in most pipes over 3", would produce a seemingly erratic flow reading. In order to produce a reasonably stable flow reading it is desirable to introduce some signal filtering. Magio 3.0 offers 7 settings from "none" to "High". The way in which the flowmeter will react is illustrated by the red line graph below. The higher the filter, the longer it will take Magnum to react to a change in flow and settle at the new level of flow. It is important to keep in mind that a high setting will make the flowmeter react very slowly, and in applications where flows change frequently this may not be a desirable setting. Generally a setting somewhere in the middle will suit most applications.

If the application is particularly turbulent or noisy it is possible to add another kind of filter called the "window". Once a steady reading has been established it dampens the signal for a few percent above and below this reading  in order to achieve as straight a line as possible. If the flow changes above or below this "window" the flowmeter reacts faster again. It is important to keep this window as small as possible in order to eliminate undesirable noise, but to keep the meter able to react to real changes in flow.

Zero Suppression allows the user to force the reading to zero if it falls below a certain percentage of flow.

When done hit "Continue".
