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.
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.
• The high oscillation frequency of the measuring tubes ensures that the correct oper-
ation 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.
3.2.1 Dimensions
Dimensions and the fitting lengths of the transmitter and sensor are on see Page 59 ff.
3.2.2 Mounting location
Entrained air or gas bubbles in the measuring tube can result in an increase in measur-
ing errors. Avoid the following locations:
• Highest point in a run. Risk of air accumulating.
• Directly upstream from an open pipe outlet in a down pipe.
