Safety instructions
1.1
Designated use
The measuring device described in these Operating Instructions is to be used only for measuring the
mass flow rate of liquids and gases. At the same time, the system also measures fluid density and
fluid temperature. These parameters are then used to calculate other variables such as volume flow.
Fluids with widely differing properties can be measured, for example:
• Chocolate, condensed milk, liquid sugar
• Oils, fats
• Acids, alkalis, lacquers, paints, solvents and cleaning agents
• Pharmaceuticals, catalysts, inhibitors
• Suspensions
• Gases, liquefied gases, 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 authorised to perform such work by the facil-
ity's owner operator. The specialist must have read and understood these Operating Instructions
and must follow the instructions it contains.
• The device must be operated by persons authorised and trained by the facility's owner-operator.
Strict compliance with the instructions in this manual is mandatory.
• Endress+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.
• 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 insu-
lated.
• 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 docu-
mentation", which is an
integral part
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 (0 Europe, 2 USA, 1 Canada).
• The measuring device complies with the general safety requirements in accordance with
EN 61010, the EMC requirements in accordance with EN 61326/A1 and NAMUR recommen-
dation NE 21/43.
• For measuring systems used in SIL 2 applications, the separate manual on functional safety must
be observed.
• The manufacturer reserves the right to modify technical data without prior notice. Your E+H dis-
tributor will supply you with current information and updates to these Operating Instructions.
of these Operating Instructions. Strict compliance with the
