1.1 Designated use
The measuring device described in this Operating Manual is to be used only for meas-
uring the flow rate of conductive fluids in closed pipes. A minimum conductivity of
20 µS/cm is required for measuring demineralized water. Most fluids can be metered,
provided they have a minimum conductivity of 5 µS/cm, for example:
• acids, alkalis, pastes, mashes, pulps,
• drinking water, wastewater, sewage sludge,
• milk, beer, wine, mineral water, yogurt, molasses, etc.
The manufacturer accepts no liability for damages resulting from incorrect use or other
than designated use.
1.2 Installation, commissioning and operation
Note the following points:
• Installation, connection to the power 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
this Operating Manual and must follow the instructions it contains.
• The device must be operated by persons authorized and trained by the facility's
owner-operator. Strict compliance with the instructions in the Operating Manual is
mandatory.
• Endress+Hauser will be happy to assist in clarifying the chemical resistance proper-
ties of parts wetted by special fluids, including fluids used for cleaning.
• If welding work is performed on the piping system, do not ground the welding appli-
ance through the Promag flowmeter.
• The installer must ensure that the measuring system is correctly wired in accordance
with the wiring diagrams. The transmitter must be grounded, unless the power supply
is galvanically insulated.
• Invariably, local regulations governing the opening and repair of electrical devices
apply.
1.3 Operational saf ety
Note the following points:
• Measuring systems for use in hazardous environments are accompanied by separate
"Ex documentation", which is an integral part of this Operating Manual. Strict compli-
ance with the installation instructions and ratings as stated in this supplementary doc-
umentation is mandatory. The symbol on the front of this supplementary Ex documen-
tation indicates the approval and the test center( 0 Europe, 2 USA, 1 Canada).
• The measuring device complies with the general safety requirements in accordance
with EN 61010, the EMC requirements of EN 61326/A1, and NAMUR recommendation
NE 21.
• Depending on the application, the seals of the process connections of the Promag H
sensor require periodic replacement.
• The manufacturer reserves the right to modify technical data without prior notice. Your
E+H distributor will supply you with current information and updates to this Operating
Manual.
