2.6 NAMUR recommendations
NAMUR is the automation technology user association in the process
industry in Germany. The published NAMUR recommendations are
accepted as the standard in field instrumentation.
The device fulfils the requirements of the following NAMUR recom-
mendations:
•
NE 21 – Electromagnetic compatibility of equipment
•
NE 43 – Signal level for malfunction information from measuring
transducers
•
NE 53 – Compatibility of field devices and display/adjustment
components
•
NE 107 – Self-monitoring and diagnosis of field devices

2.7 Radio license for Europe
The instrument was tested according to the latest issues of the har-
monized standards:
•
EN 302372 - Tank Level Probing Radar
•
EN 302729 - Level Probing Radar
It is hence approved for use inside and outside closed vessels in
countries of the EU.
In EFTA countries, the use is approved as far as these standards
were implemented.
For operation inside of closed vessels, the following conditions must
be fulfilled:
•
The instrument must be permanently mounted on a closed vessel
made of metal, reinforced concrete, or comparable attenuating
materials
•
Flanges, process fittings and mounting accessories must ensure
the microwave impermeability of the vessel and not let the radar
signal escape to the outside
•
If necessary, existing viewing windows in the vessel must be
coated with a microwave impermeable material (e.g. electrically
conductive coating)
•
Manholes and flanges on the vessel must be closed and sealed to
avoid penetration of the radar signal
•
The instrument should be preferably mounted on top of the vessel
with antenna orientation downward
•
The instrument must only be installed and maintained by appropri-
ately qualified staff
