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 (incl. 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, laitance, ore slurry (containing sand or stone), mud, silt.
Resulting from incorrect use or from use other than that designated the operational safety of the
measuring devices can be suspended. The manufacturer accepts no liability for damages being
produced from this.
1.2
Installation, commissioning, 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 by persons authorized and trained by the facility's owner-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 in the degree of contamination in the process can result in changes of the
chemical resistance properties. Therefore, Hauser can not guarantee or accept liability
for the chemical resitance properties of the fluid wetted materials in a specific application. The
user is responsible for the choice of fluid wetted materials in regards 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. The symbol on the front of this supplementary Ex documentation indicates the
approval and the certification body (e.g.
0
Europe,
1
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.
