The radar sensor as a distance measuring instrument 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.

max. meas. distance
2 Max. level

min. meas. distance
For this adjustment, the distance is entered for min. and max. level.
If these values are not known, an adjustment with distances, for
example, of 10 % and 90 % is also possible. Starting point for these
distance specifications is always the seal surface of the thread or
flange.
With the function "
Echo curve memory
" the echo curve can be saved
at the time of setup. This is generally recommended; for using the As-
set Management functions it is absolutely necessary. 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 over the operating time. In addition, the echo curve of the
setup can be also displayed in the echo curve window and compared
with the actual echo curve.
