•
Solid dusty
• For dusty bulk solids
• The filters are set in such a way that even relatively weak wanted signals are detected
•
Conveyor belt
• For bulk solids with rapid changes in the level, e.g. conveyor belts
• Low values are set for the filters.
→ Fast response time, possibly unstable measured value
•
Test: no filter
For service and diagnostics only
All the filters are switched off.

D
Distance (sensor membrane/product)
E
Empty calibration = zero point
F
Full calibration = measuring span
L
Level
BD Blocking distance
SD Safety distance
Empty calibration function (005)
Specify the distance E from the sensor membrane = reference point of the measurement to
the minimum level (zero point).
Torispherical head or conical outlets: the zero point should not be lower than the
point where the ultrasonic wave hits the bottom of the tank.
Blocking distance function (059)
The blocking distance (BD) of the sensor is displayed.
After the basic setup, enter the safety distance (SD) in the
Safety distance (015)
function
When entering the full distance, make sure that the maximum level does not enter
the blocking distance.
