2.1
Safety notes
For safety reasons it is important that the following points, especially those marked with a warning
sign, are read and understood before the system is installed:
•
Installation, connection, commissioning and service must be carried out by personnel who
are qualified and authorized to do so.
•
It is very important for any person working with the equipment to read and understand the
instructions and directions provided in this manual and follow instructions and directions
before using the equipment.
•
Only personnel authorized and trained by the owner of the equipment may operate the
equipment.
•
Installation personnel must ensure that the measuring system is correctly connected in
accordance with the connection diagram.
•
For applications involving high working pressures or media that can be dangerous to
people, surroundings, equipment or other in the event of pipe fracture, Siemens recommends
taking precautions such as special placement, shielding or installation of a safety guard or
safety valve prior to installation of the sensor.
•
Repair and service may be performed by approved Siemens Flow Instruments personnel
only.
2.2
Manufacturer’s design and safety statement
•
Responsibility for the choice of flowmeter pipe material as regards abrasion and corrosion
resistance lies with the purchaser. The effect of any change in process medium during
operation of the meter should be taken into account. Incorrect selection of flowmeter pipe
material could lead to failure of the flowmeter.
•
Stresses and loading caused by earthquakes, traffic, high winds and fire damage are
not
taken
into account during flowmeter design.
