6 Installation
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)�
• 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�
• When operating the unit in small tanks (probe lengths shorter than 200 mm
and less than 300 mm distance to the tank wall), mount the unit off-centre
(eccentrically) to prevent possible interference from tank resonances�
• 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
