3.1.3 Storage
Note the following points:
• Pack the measuring device in such a way as to protect it reliably against impact for storage (and
transportation). The original packaging provides optimum protection.
• The permissible storage temperature is –40...+80 °C (preferably +20 °C).
• Do not remove the protective covers or caps on the process connections until you are ready to
install the device.
• The measuring device must be protected against direct sunlight during storage in order to avoid
unacceptably high surface temperatures.
3.2 Installation conditions
Note the following points:
• No special measures such as supports are necessary. External forces are absorbed by the
construction of the instrument, for example the secondary containment.
• The high oscillation frequency of the measuring tubes ensures that the correct operation of the
measuring system is not influenced by pipe vibrations.
• No special precautions need to be taken for fittings which create turbulence (valves, elbows,
T-pieces, etc.), as long as no cavitation occurs.
• For mechanical reasons and in order to protect the pipe, it is advisable to support heavy sensors.
3.2.1 Dimensions
All the dimensions and lengths of the sensor and transmitter are provided in the separate
documentation “Technical Information”.
3.2.2 Mounting location
Accumulated air or gas bubbles in the measuring tube can result in an increase in measuring errors.
Avoid the following locations:
• Highest point of a pipeline. Risk of air accumulating.
• Directly upstream of a free pipe outlet in a vertical pipeline.
