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:
• Oils, fats
• Acids, alkalis, lacquers, paints, solvents and cleaning agents
• Pharmaceuticals, catalysts, inhibitors
• Suspensions
• Gases, liquefied gases, etc.
• Chocolate, condensed milk, liquid sugar
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 Instruction 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, 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 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.
