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
Dimensions and the fitting lengths of the transmitter and sensor are on Page 102 ff.
3.2.2 Mounting location
Entrained 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.
