1 Safety instructions
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
μ S/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,
• Cement slurry, ore slurry (containing sand or stone), mud, silt
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.
• 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, 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.
• The Promag 55 flow measuring device can also measure extremely abrasive fluids, e.g. ore slurry,
cement etc. To protect the measuring tube lining from excessive abrasion, the use of additional
liner protection plates is recommended in such cases.
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).
