constant. Keep in mind that layer interfaces can cause faulty meas-
urements.
If you want to measure the total height of both liquids reliably, please
contact our service department or use an instrument specially de-
signed for interface measurement.
Through this selection the operating range of the sensor is adapted
to the vessel height, which considerably increases measurement
certainty under different basic conditions.
The min. adjustment must be carried out independently of this.
Enter the requested parameters via the appropriate keys, save your
settings with
[OK]
and jump to the next menu item with the
[ESC]
and
the
[->]
key.
Apart from the medium and the application, the vessel form itself can
influence the measurement. To adapt the sensor to these measuring
conditions, this menu item offers different options for vessel bottom
and ceiling for certain applications.
Enter the requested parameters via the appropriate keys, save your
settings with
[OK]
and jump to the next menu item with the
[ESC]
and
the

key.
Since the radar sensor is a distance measuring instrument, it is the
distance from the sensor to the product surface that is measured. To
indicate the actual level, the measured distance must be assigned to
a certain height percentage.
To perform the adjustment, enter the distance with full and empty ves-
sel, see the following example:
