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 liquids in closed pipes.
A minimum conductivity of 20 µS/cm is required for measuring demineralized water. Most liquids
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.
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
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 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.
• Hauser will be happy to assist in clarifying the chemical resistance properties of parts
wetted by special fluids, including fluids used for cleaning. However, the user is responsible for
the choice of fluid wetted materials as regards to their in-process resistance to corrosion. The
manufacturer refuses to accept liability.
• If carrying out welding work on the piping, the welding unit must not be grounded by means of
the measuring device.
• 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
isolated.
• Invariably, local regulations governing the opening and repair of electrical devices apply.
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 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 supplementary Ex documentation indicates the approval and the
certification body (

• The measuring device complies with the general safety requirements in accordance with
EN 61010, the EMC requirements of EN 61326/A1 (IEC 1326), and NAMUR recommendations
NE 21, NE 43 and NE 53.
• 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
Hauser distributor will supply you with current information and updates to this
Operating Manual.
