Measurement from the outside through plastic walls
•
Observe engineering hints on Page 14.
•
If possible, use an antenna 100 mm / 4".
Standard installation
When mounting in a tank, please observe
engineering hints on Page 14 and the
following points:
•
Marker is aligned towards tank wall.
•
The marker is always exactly in the
middle between two bolt-holes in the
flange.
•
After mounting, the housing can be
turned 350° in order to simplify access to
the display and the terminal
compartment.
•
For optimum measurement, the horn
antenna should extend below the
nozzle. Nozzle heights up to 500 mm
can be accepted if this should not be
possible due to mechanical reasons.
Note!
Please contact Hauser for
application with higher nozzle.
•
The horn antenna must be aligned
vertically.
Caution!
At not vertically aligned horn antenna
can be reduced the maximum range.
