Distance Filter Factor
This parameter defines the amount of product level filtering (1 = 100%).
A low Filter Factor means that a new level value is calculated by adding a small fraction (for
instance 1%) of the level change to the last known level value. It makes the level value
steady but the device reacts slowly to level changes in the tank.
A high filter factor means that a larger fraction of the level change is added to the current
level value. This setting makes the device react quickly to level changes but the presented
level value can sometimes be somewhat jumpy.
Jump Filter
The Jump Filter is typically used for applications with turbulent surface and makes the echo
tracking work smoother as the level passes, for example, an agitator. If the surface echo is
lost and a new surface echo is found, the Jump Filter makes the level gauge wait some
