– Instrument demonstration
– Object recognition/monitoring (additional settings required)
•
Properties, sensor:
– Sensor accepts all measured value changes within the measur-
ing range immediately
– High sensitivity to interference, because virtually no averaging
Caution:
Ifliquidswithdierentdielectricconstantsseparateinthevessel,for
example through condensation, the radar sensor can detect under
certain circumstances only the medium with the higher dielectric
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.
Apart from the medium and the application, the vessel form itself can

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.
Through this selection the operating range of the sensor is adapted
to the vessel height, which considerably increases measurement
certaintyunderdierentbasicconditions.
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.
Since the radar sensor is a distance measuring instrument, the
distance from the sensor to the product surface is measured. To
indicate the actual level, an allocation of the measured distance to the
percentage height must be carried out.
To perform the adjustment, enter the distance with full and empty ves-
sel, see the following example:
