2.1 Safety notes
For safety reasons it is important that the following points, especially the points marked with a
warning sign, are read and understood before the system is being installed:
•
Installation, connection, commissioning and service must be carried out by qualified and
authorized personnel.
•
It is very important that the users read and understand the instructions and directions
provided in this manual and that they follow the instructions and directions before taking the
equipment into use!
•
People who are authorized and trained by the owner of the equipment may operate the
equipment.
•
The installation must ensure that the measuring system is correctly connected and is in
accordance with the connection diagram.
•
In applications with working pressures/media that can be dangerous to people, surroundings,
equipment, or others in case of pipe fracture, we recommend that special precautions such
as special placement, shielding, or installation of a security guard or a security valve should
be made when the sensor is being installed.
•
Siemens Flow Instruments assist by estimating the chemical resistance of the sensor
parts that are in connection with the media, but it is at any time the customer’s responsibility,
which materials are chosen, and Siemens Flow Instruments takes no responsibility if the
sensor corrodes!
•
Equipment used in hazardous areas must be Ex approved and marked for Europe and
UL for USA.
It is required that the special directions provided in the manual and in the Ex certificate
must be followed!

Installation of the equipment must comply with national regulations.
Example: EN 60079-14 for Denmark.
•
Repair and service can be done by approved Siemens Flow Instruments personnel only.

The p/T ratings indicate the relation between the maximum allowable pressure PN and
the maximum allowable temperature.
