1.1

Designated use

The measuring device described in this Operating Manual is to be used only for measuring
the flow rate of conductive fluids in closed pipes.
All fluids (including demineralized water) can be metered, provided they have a minimum
conductivity of 5 μS/cm, for example:
• acids, alkalis, pastes, paps, pulps, black liquor, green liquor
• drinking water, wastewater, sewage sludge
• milk, beer, wine, mineral water, yoghurt, molasses, fruit mash
Incorrect use or use other than that designated may result in the operational safety of the
measuring devices being suspended. The manufacturer accepts no liability for damages
resulting from this.
1.2

Installation, commissioning and operation

Note the following points:
• Installation, connection to the electricity supply, commissioning and maintenance of the
device must be carried out by trained, qualified specialists authorized to perform such work
by the facility' s owner-operator. The specialist must have read and understood these
Operating Instructions and must follow the instructions they contain.
• The device must be operated only by persons authorized and trained by the system
operator. Strict compliance with the instructions in the Operating Instructions is
mandatory.
• Endress+Hauser is willing to assist in clarifying the chemical resistance properties of parts
wetted by special fluids, including fluids used for cleaning. However, small changes in
temperature, concentration or the degree of contamination in the process can result in
changes to the chemical resistance properties. For this reason, Endress+Hauser does not
accept any responsibility with regard to the corrosion resistance of materials wetted by
fluids in a specific application. The user is responsible for the choice of wetted materials
with regard to their in-process resistance to corrosion.
• If welding work is performed on the piping system, do not ground the welding appliance
through the flowmeter.
• The installer must ensure that the measuring system is correctly wired in accordance with
the wiring diagrams. The transmitter must be grounded, except in cases where special
protective measures have been taken (e.g. galvanically isolated power supply SELV or
PELV).
• Always note the regulations applicable in your country to the operation, maintenance and
repair of electrical devices. Special instructions relating to the device can be found in the
relevant sections of the documentation.
1.3

Operational safety

Note the following points:
• Measuring systems for use in hazardous environments are accompanied by separate
"Ex documentation", which is an integral part of these Operating Instructions. Strict
compliance with the installation instructions and ratings as stated in this supplementary
documentation is mandatory. Depending on the approval and certification agency, the
relevant symbol is depicted on the front page of the supplementary documentation on Ex
ratings (e.g. 0 Europe, 2 USA, 1 Canada).
• The measuring device meets the general safety requirements according to EN 61010-1
and the EMC requirements according to IEC/EN 61326 in addition to the NAMUR
recommendations NE 21, NE 43 and NE 53.
