For optimum operation the unit should be installed as near as possible to
•
the tank wall� Distance between the rod and the tank wall: minimum 40 mm,
maximum 300 mm�
The following minimum distances between the rod and tank walls, objects in

the tank (B), tank bottom and other level sensors must be adhered to:
50mm
10mm
100mm
B
40mm
For tank walls which are not straight, steps, supports or other structures in the
•
tank a distance of 50 mm to the tank wall must be adhered to�
For rod lengths > 70 cm the rod can be considerably deflected by movement of
•
the medium� To avoid contacting the tank wall or other structures in the tank in
such cases, the minimum distances should be increased� Reference values:
Rod length
Distance to the tank wall or structures in the tank
70���100 cm

100���160 cm
180 mm
If the medium is strongly polluted, there is the risk that a bridge forms between
