Safety instructions
1.1 Designated use
• The measuring device should only be used to measure the mass flow rate of liquids and gases.
At the same time, the measuring device also measures the density and fluid temperature.
These parameters are then used to calculate other process variables such as volume flow.
• Any use other than that described here compromises the safety of persons and the entire
measuring system and is, therefore, not permitted.
• The manufacturer is not liable for damage caused by improper or non-designated use.
1.2 Installation, commissioning and operation
• The measuring device must only be installed, connected, commissioned and maintained by
qualified and authorized specialists (e.g. electrical technicians) in full compliance with the
instructions in these Brief Operating Instructions, the applicable norms, legal regulations and
certificates (depending on the application).
• The specialists must have read and understood these Brief Operating Instructions and must
follow the instructions they contain. If you are unclear on anything in these Brief Operating
Instructions, you must read the Operating Instructions (on the CD-ROM). The Operating
Instructions provide detailed information on the measuring device.
• The measuring device may only be installed in a de-energized state.
• Repairs may only be performed if a genuine spare parts kit is available and this repair work is
expressly permitted.
• If performing welding work on the piping, the welding unit may not be grounded by means of
the measuring device.
1.3 Operational safety
• The measuring device is designed to meet state-of-the-art safety requirements, has been
tested, and left the factory in a condition in which it is safe to operate. Relevant regulations
and European standards have been observed.
• Observe the technical data on the nameplate!
• The technical staff must ensure that the measuring device has been correctly wired and
grounded as per the wiring diagrams.
• With regard to special fluids, including fluids used for cleaning, Hauser will be happy
to assist in clarifying the corrosion-resistant properties of wetted materials. However, minor
changes in temperature, concentration or in the degree of contamination in the process may
result in variations in corrosion resistance.
For this reason, Hauser does not accept any responsibility with regard to the
corrosion resistance of wetted materials in a specific application. The user is responsible for
the choice of suitable wetted materials in the process. A sensor version which allows the
sensor housing be monitored should be used for critical fluids.
