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.
A minimum conductivity of 20 μ S/cm is required for measuring demineralized water. Most liquids
can be measured as of a minimum conductivity of 5 μ S/cm.
Examples:
• Acids, alkalis,
• Drinking water, wastewater, sewage sludge,
• Milk, beer, wine, mineral water, etc.
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 and operation
Please note the following:
• 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 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.
• With regard to special fluids, including fluids used for cleaning, Hauser will be happy to
assist in clarifying the corrosion-resistant properties of wetted materials.
However, minor changes in temperature, concentration or in the degree of contamination in the
process may result in variations in corrosion resistance. For this reason, Hauser does not
accept any responsibility with regard to the corrosion resistance of wetted materials in a specific
application.
The user is responsible for the choice of suitable wetted materials in the process.
• If welding work is performed on the piping system, do not ground the welding appliance 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 apart from when special protective measures
are taken (e.g. galvanically isolated SELV or PELV power supply)
• Invariably, local regulations governing the opening and repair of electrical devices apply.
1.3 Operational safety
Please note the following:
• Measuring systems for use in hazardous environments are accompanied by separate Ex
documentation, which is an integral part of this Operating Manual. Strict compliance with the
installation instructions and ratings as stated in this supplementary
documentation is mandatory. The symbol on the front of this Ex documentation indicates the
approval and the certification body (e.g.
0
Europe,
2
USA,
1
Canada).
• The measuring device complies with the general safety requirements in accordance with
EN 61010-1, the EMC requirements of IEC/EN 61326 and NAMUR Recommendations NE 21
and NE 43.
• Depending on the application, the seals of the process connections of the Promag H sensor require
periodic replacement.
