1.3 Safety instructions
1.3.1 Intended use of the equipment
The FLOWSIC600 measuring system is used for measuring the actual volumetric flow rate
of gases transported in pipelines. It can be used for measuring the actual corrected vol
-
ume and the speed of sound in gases.
The measuring system shall only be used as specified by the manufacturer and as set forth
below. Always observe the following information:
● Make sure the use of the equipment complies with the technical data, information
about the permitted use, assembly and installation specifications and ambient as well
as operating conditions. Relevant information is provided in the order documentation,
type plate, certification documents and this manual.
● Any actions for the purpose of maintaining the value of the equipment, e.g. service and
inspection, transport and storage etc., shall be performed as specified.
● Do not expose the equipment to mechanical stress, such as pigging.
● The flooding of the FLOWSIC600 with any liquid (e.g. for pressure or leakage tests) is
deemed improper use. The consequences of such actions can not be foreseen or
estimated. Improper use may result in failure of the ultrasonic transducers and
consequently, failure of the entire flow meter.
Should it be necessary to flood the FLOWSIC600, please contact the manufacturer prior to
doing so. In addition, the following instructions must be strictly adhered to:
1.4 Authorized staff
Persons responsible for safety shall ensure the following:
● Any work on the measuring system shall only be carried out by qualified staff and must
be approved by skilled staff responsible for the plant.

Due to their professional training, knowledge and vocational experience, as well as
their knowledge of the relevant standards, regulations, health and safety regulations
and equipment conditions, qualified persons shall be assigned by the person
responsible for personal and plant safety to carry out such work. Qualified persons
must be able to identify possible dangers and to take preventive action in due time.

Skilled persons are defined in DIN VDE 0105 and IEC 364, or comparable standards.
● Skilled persons shall have precise knowledge of process-specific dangers, e.g. due to
the effects of hot, toxic and pressurized gases, gas-liquid mixtures and other process
media, and of the design and working principle of the measuring system and shall have
received and be able to document appropriate training.
● In hazardous areas with potentially explosive atmospheres, wiring and installation shall
only be carried out by staff trained according to EN /IEC 60079-14 and according to
national regulations.
WARNING:
 The pressure during flooding may not exceed more than 1,2 times the
nominal pressure (when transducers are assembled).
