Threshold:
The THRESHOLD creates the primary condition for the measuring system for tracking the separation
zones based on the selected algorithm. The system searches for a point (on the graphic display) where
the signal strength has at least a "threshold value percentage" of the strongest signal (100% of the
display height).
•
Example 1: Algorithm: LEFT, THRESHOLD: 30.
The signal data is processed from left to right. The first signal peak, which has at least 30% of the
size of 100% of the display height, is localised.
•
Example 2: Algorithm: RIGHT, THRESHOLD 20.
The signal data is processed from right to left (as viewed on the graphic display). The first signal
peak, which has at least 20% of the size of 100% of the display height, is localised.
Setting range: 0 ... 100
History:
Adjust the tracking speed of the separation zone arrow relative to the movement of the candidates
(= possible separation zones). For example, if you set a history number of 10, the display value (index
curve) is defined by the last 10 candidate positions.
Setting range: 0 ... 200
G min:
Set the minimum size of the measuring window above and below the measured variable.
Setting range: 0 ... 10m
G max:
Set the maximum size of the measuring window above and below the measured variable.
Setting range: 0 ... 10m
Candidates:
Set the number of possible separation zones which the sensor should search for.
Setting range: 0 ... 3
Sensitivity:
Define the signal sensitivity.
Setting range: 0 ... 100
Wall zone:
Set the number of metres above the basin bottom which should be hidden, e.g. because there is a
constant minimum thickness of sludge layers in the basin.
Setting range: 0 ... 100m
Set zone:
Set whether the sensor should track one particular separation zone (ON) or search for every available
separation zone (OFF).
Setting range: ON / OFF
Cell limit:
Set the time between measuring window refreshes.
Setting range: 1 ... 50
Delta Y coeff:
Define the relationship between the height and width of the display signal.
•
Low delta Y coeff gives a low, wide signal peak
•
High delta Y coeff gives a high, narrow signal peak
Setting range: 1 ... 100
