3.2 Principle of operation

The instrument is suitable for applications in liquids and bulk solids in

vessels under dicult 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 tting nor a vessel opening are required. The instru-

ment is thus ideal for retro installation.

In radiation-based measurement, a Caesium-137 or Cobalt-60 iso-

tope emits focussed gamma rays that are attenuated when penetrat-

ing 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.

3.3 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 of standard instruments consists of environment-

friendly, recyclable cardboard. 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.
