Installation instructions
Installation conditions
Note!
The sensor requires a fully developed flow profile for correct monitoring. For this reason,
steadying sections (5x DN) must be provided in the pipe after a pump, pipe bend, internal
fittings and cross-sectional changes.
• The onsite display can be rotated electronically 180°, see “Onsite operation” section.
• The upper housing section can be rotated mechanically up to 310°.
Do not turn the device into the process connection thread
at the housing. Always install the device at the spanner flats
(Figure 4, item 1). Use a suitable open-ended wrench for
this task (see table of page 5). ATTENTION
