2.4 Recommendations for hygienic and self-
draining applications
For optimal cleanability and drainability:
• If possible, install the sensor in a vertical pipeline with the process fluid flowing upward
through the sensor.
• The minimum angle of inclination of the sensor depends on the process fitting. See
Figure 2-1 and Table 2-3 .
• For clean-in-place (CIP) applications, Micro Motion recommends using the generally-
accepted flow velocity of at least 1.5 m/s for cleaning the sensor.
• If the process piping must be larger than the sensor, eccentric reducers may be used to
ensure full drainability. In this case, the process end connections for the piping and
sensor must be the same size. See
Figure 2-2 .
Note
As part of the cleaning process, you can purge skid-based systems with nitrogen at the
end of the cleaning cycle. When using eccentric reducers, it is possible to trap gas in
the section of process piping adjacent to the reducer. Sensor performance can be
impacted by intermittent flow of the captured gas in a liquid fluid stream.
