1 Safety instructions
1.1 Designated use
The measuring device described in these Operating Instructions is to be used only for measuring the
flow rate of liquids in closed pipes.
Examples:
• Acids, alkalis, paints, oils
• Liquid gas
• Ultrapure water with low conductivity, water, wastewater
As well as measuring the volume flow, the sound velocity of the fluid is also always measured.
Different fluids can be distinguished or the fluid quality can be monitored.
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 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 these 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 corrosion resistance properties. Therefore, Hauser
cannot guarantee or accept liability for the corrosion resistance properties of wetted materials in
a specific application.
The user is responsible for choosing suitable wetted materials in the process.
• If carrying out welding work on the piping, the welding unit may 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, except in cases where special protective
measures have been taken (e.g. galvanically isolated power supply SELV or PELV).
• 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 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 inspection authority (e.g.
0
Europe,
2
USA,
1
Canada).
• The measuring system complies with the general safety requirements in accordance with
EN 61010-1, the EMC requirements of IEC/EN 61326, and NAMUR Recommendation NE 21
and NE 43.
• 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 Instructions.
