3.1 Intended
Use
The instrument described in this manual is exclusively to use for measuring the thermal mass flow of
gases. At the same time, the gas temperature is measured too.
The KEC-2 can be configured for measuring a predetermined range of pure gases or of
gas mixtures.
Consumption measurement of gases such as Air, oxygen, nitrogen, carbon dioxide, argon, etc.
and with ATEX approval explosive gases such as natural gas, methane, propane and hydrogen.
Improper or incorrect use the operational reliability will be canceled. The manufacturer is not liable for
any damage resulting by improper or incorrect use.
3.2
Installation and commissioning
Installation, electrical installation, commissioning, operation and maintenance of the device
must only be carried by qualified personnel, which were authorized by the plant operator.
The personnel must read the operating instructions and understand and follow their
instructions.
If carrying out welding work on the pipeline the grounding of the welding unit is not allowed to
be done over the KEC-2 itself.
The installer has to ensure that the KEC-2 is connected according to the electrical
connection diagrams properly. The sensor must be grounded, unless special protective
measures have been taken (e.g. galvanically isolated power supply)
The existing/ applicable national regulations governing opening and repair of the device have
to be applied.
When using the KEC-2 (ATEX Version) hazardous areas, in addition with the standard manual
a separate Ex documentation is enclosed. The installation instructions and connection values
indicated in these must also be observed (in preparation).
The device fulfills the general safety requirements in accordance with EN 61010-1,
the EMC requirements of IEC / EN 61326 and NAMUR recommendation NE 43.
