3.2
Principle of operation
The instrument is suitable for applications in liquids and bulk solids in
vessels under difficult process conditions. There are application pos-
sibilities in nearly all areas of industry.
The level is detected contactlessly right through the vessel wall.
Neither a process fitting nor a vessel opening are required. The instru-
ment is thus ideal for retro installation.
In radiometric measurement, a Caesium-137 or Cobalt-60 isotope
emits focussed gamma rays that are attenuated when penetrating
the vessel wall and the medium. The PVT detector on the opposite
side of the tank receives the radiation, whose strength is dependent
on the level. The measuring principle has proven to be very reliable
in conjunction with extreme process conditions because it measures
contactlessly from outside through the vessel wall. The measuring
system ensures maximum safety, reliability and plant availability,
independently of the medium and its properties.

Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging consists of environment-friendly, recyclable card-
board. For special versions, PE foam or PE foil is also used. Dispose
of the packaging material via specialised recycling companies.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
