The radar sensor measures the distance from the sensor to the
product surface. For indication of the real level, an allocation of the
measured distance to the percentage height must be carried out.

Fig. 12: Parameter adjustment example min./max. adjustment
1 Min. level = max. measuring distance
2 Max. level = min. measuring distance
For this adjustment, the distance is entered when the vessel is full
and nearly empty. If these values are not known, an adjustment with
other distances, for example, 10 % and 90 % is also possible. Starting
point for these distance specifications is always the seal surface of
the thread or flange.
The function "
Echo curve memory
" makes it possible to save the echo
curve at the time of setup. This is generally recommended, and it is
absolutely necessary to do this if you want to use the Asset Manage-
ment functions. If possible, the curve should be saved with a low level
in the vessel.
With the adjustment software PACTware and the PC, the high resolu-
tion echo curve can be displayed and used to recognize signal
changes during operation. In addition, the echo curve of setup can be
displayed in the echo curve window and compared with the current
echo curve.
