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 personnel
who are qualified and authorized to do so.
•
It is very important that the same people have read and understood the instructions and
directions provided in this manual and that they follow the instructions and directions
before putting the equipment into use!
•
People who are authorized and trained by the owner of the equipment may operate the
equipment.
•
The installer must ensure that the measuring system is correctly connected and is in
accordance with the connection diagram. The transmitter has to be earthed by means
of a 4 mm
2
potential equalising conductor.
•
In applications where the operating pressure or media can be hazardous in the event
of a pipe failure, we recommend that special precautions are taken during the installation
of the sensor, such as sensor location, guarding or the use of a pressure relief valve.
•
Siemens Flow Instruments can provide assistance with the selection of sensor parts in
contact with the media. However, the full responsibility for the selection rests with the
customer and Siemens Flow Instruments can take no responsibility for any failure due
to material incompatibility.
•
Equipment used in hazardous areas must be Ex-approved and marked .
It is required that the "Special Conditions for Safe Use" provided in the manual and in
the Ex certificate are followed!
•
Installation of the equipment must comply with national regulations.
Example EN 60079-14 for the European Community.
•
Repair and service can be done by approved Siemens Flow Instruments personnel only.
1. Introduction
1. Responsibility for the choice of lining and electrode materials with regard to their abrasion
and corrosion resistance lies with the purchaser; the effect of any change in process medium
during the operating life of the flowmeter should be taken into account. Incorrect selection
of lining and/or electrode materials could lead to a failure of the flowmeter.
2. It is the responsibility of the user to ensure that stresses and loading caused by earthquakes,
traffic, high winds and fire damage are taken into account during installation, when
appropriate. These forces are not taken into account during flowmeter design.
3. It is the responsibility of the user to ensure that the flowmeter is installed such that it does not
act as a focus for pipeline stresses. External loading are not taken into account during
flowmeter design.
4. During operation do not exceed the pressure and/or temperature ratings indicated on the
data label or in the installation instructions.
5. It is the responsibility of the user to ensure that all installations include over pressure
protection, means for draining/venting, and that adequate protection is provided to minimize
any risk of contact with hot surfaces.
6. Under the Pressure Equipment Directive this product is a pressure accessory, and not
approved for use as a safety accessory, as defined by the Pressure Equipment Directive.
7. Removal of the terminal box except by Siemens Flow Instruments or their approved agents
will invalidate the PED conformity of the product.
In accordance with the Pressure Equipment Directive (97/23/EC)
