6.1 Installation location / environment
•
Vertical installation from the top is preferred�
6.1.1 Unit with single probe
• For a safe function, the unit requires a launching plate (→ 6.4).
•
For optimum operation the unit is to 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 probe 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:
Probe length
Distance to the tank wall or structures in the tank
70���100 cm
100 mm
100���160 cm
180 mm
•
If the medium is strongly polluted, there is the risk that a bridge forms
