The level meter must not be installed in places with direct
solar radiation and must be protected against the effects of local
weather.
If installation in places with direct solar radiation is inevitable, it is
necessary to mount a shielding cover above the level meter (Fig.
13).
It is suitable to run the cable under a cable bushing (obliquely down i n
slack) according to Fig.14 to prevent penetration of humidity into the
housing. In this way, rain and condensing water can flow off freely.
The cable bushing and connector have to be sufficiently tightened to
prevent penetration of humidity.
To lower the minimum distance to the measured medium,
a reflection board made from solid, even and smooth material can
be installed to the level meter. Then the tank can be filled nearly up to
the maximum height. This solution is suitable for open tanks and
reservoirs (Fig. 15).
