1.1 Designated use
The measuring device described in these Operating Instructions is to be used only for measuring the
mass flow or volume flow rate of liquids. Fluids with widely differing properties can be measured.
Examples:
• Additives
• Oils, fats
• Acids, alkalis
• Varnishes, paints
• Suspensions
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 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 of the chemical
resistance properties. Therefore, Hauser can not guarantee or accept liability for the
chemical resistance 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.
• The installer must ensure that the measuring system is correctly wired in accordance with the
wiring diagrams.
• 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 the supplementary Ex documentation indicates the
approval and the testing body (
0
Europe,
2
USA,
1
Canada).
• The measuring device complies with the general safety requirements in accordance with
EN 61010, the EMC requirements of IEC/EN 61326 and NAMUR recommendation NE 21.
• The manufacturer reserves the right to modify technical data without prior notice. Your
Hauser distributor will supply you with current information and updates to these
Operating Instructions.
