•
Extreme foam / Extreme dust
At extreme foam resp. extreme dust the measuring signal will be damped very much.
The activation of this function allows at such applications a significant improvement of the signal
evaluation.
Default > no
•
Fast change rate
The measured signal can be checked for plausibility and only very fast jumpy signal signal changes
will be suppressed.
Default > no
5 .6 .2 Commissioning
The commissioning function can be used to adapt the device to the constructive conditions.
Therefore the device must be operated in it’s finally installed position at the maximum possible
distance resp. at the lowest possible known filling level.
After setting the vessel type the detected measuring value must be confirmed or possibly corrected.
Afterwards the detection of the envelope curve for the error echo suppression is processed.
Error echoes causing installations, positioned below the filling level when processing the
commissioning function, cannot be detected.
5 .6 .3 Min/Max-Adjustment
The min/max-adjustment set the measuring range limits.
2 points are defined, that set the ratio of the measured distance signal and the operating range of the
device.
The current measuring value is indicated in the display.
The input of the measuring range limits 0% and 100% are not mandatory. Values within the
measuring range e.g. 11% and 87% can be also input. In this case there is an automatic calculation
to 0% resp. 100%. The higher the difference between these points, the more precise is the following
calculation.
The min/max-adjustment is relevant for linearization, signal output and display scaling.
•
Lower adjustment value
•
Upper adjustment value
The input range is indefinite.
Default > Lower calibrated measuring value = 0% / Upper calibrated measuring value = 100%
5 .6 .4 Pulse rate – E
The pulse rate defines the measurement velocity resp. the repetition rate of the ultrasonic
measurement pulses.
The use of a slower pulse rate (t
p
) can be used for energy saving and also for conservation of the
sensor (reduction of component stress due to high energetic ultrasonic signals).
The use of a slower pulse rate extends the actualization time of display and outputs by the respective
factor.
•
very fast – maximum pulse rate (see chapter „Technical Data“) x factor 1
•
fast – maximum pulse rate (see chapter „Technical Data“) x factor 0,5
•
slow – maximum pulse rate (see chapter „Technical Data“) x factor 0,25
Default > very fast
