2.2.4 Notes on special mounting situations

Installation at an angle

• For mechanical reasons, rod probes should

be installed as vertically as possible.

• If installing at an angle, the probe length

must be limited, depending on the angle

of installation.

– Up to 1 m = 30°

– Up to 2 m = 10°

– Up to 4 m = 5°

2.2.5 Special information on interface measurement

Installation in horizontal cylindrical, upright and underground tanks

• Use coax probes or rod probes in the bypass/stilling well. A segmented probe is available as a

special version for longer measuring ranges.

• Any distance from the wall is possible for coax probes or rod probes in the stilling well. In the

case of rod probes, it must be ensured that the probe does not come into contact with the wall.
