Proline Promass 80A, 83A
Installation instructions
Endress+Hauser
Operating conditions: Installation
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, Tpieces, etc.),
as long as no cavitation occurs.
• For mechanical reasons and to protect the pipe, support is recommended for heavy sensors.
Mounting location
Entrained air or gas bubbles in the measuring tube can result in an increase in measuring errors.
For this reason, avoid the following mounting locations in the pipe:
• Highest point of a pipeline. Risk of air accumulating.
• Directly upstream from a free pipe outlet in a vertical pipeline.
Mounting location
Notwithstanding the above, the installation proposal below permits installation in an open vertical pipeline.
Pipe restrictions or the use of an orifice with a smaller cross-section than the nominal diameter prevent the
sensor running empty while measurement is in progress.
