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 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.
Examples:
• Chocolate, condensed milk, liquid sugar
• Oils, fats
• Acids, alkalis, lacquers, paints, solvents and cleaning agents
• Pharmaceuticals, catalysts, inhibitors
• Suspensions
• Gases, liquefied gases etc.
The operational safety of the measuring devices cannot be guaranteed if the system is used
incorrectly or used for purposes other than those intended. 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. Qualified personnel must have read and understood these Operating
Instructions and must follow the instructions contained therein.
• The device may be operated only 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.
• If carrying out welding work on the piping, never ground the welding unit 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 earthed unless special protection measures have been
taken e.g. galvanically isolated power supply SELV or PELV (SELV = Save Extra Low Voltage;
PELV = Protective Extra Low Voltage).
• Invariably, local regulations governing the opening and repair of electrical devices apply.
