Endress+Hauser 7
1 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 fluids 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 facility'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 the Operating Instructions 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 for 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 insulated.
• 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 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 of EN 61326/A1 and NAMUR recommendation
NE 21/43.
• The manufacturer reserves the right to modify technical data without prior notice. Your
E+H distributor will supply you with current information and updates to these
Operating Instructions.
