Safety instructions
Designated use
The Bulletin 839E is a flow switch for measurement and monitoring of mass flow rates in
industrial processes. The device has been safely built with state-of-the-art technology and
meets the applicable requirements and EC Directives. It can, however, be a source of
danger if used incorrectly or for anything other than the designated use.
Installation, commissioning and operation
Only personnel familiar with these types of products and associated machinery should
plan or implement the installation, start-up, configuration, and subsequent maintenance
of the Bulletin 839E flow switch. Failure to comply may result in personal injury and/or
equipment damage.
Operational safety
• Funtional Safety
The 839E flow switch was developed according to standard IEC 61010.
• Ex-area
The 839E is not approved for use in Ex-areas.
Return
Before returning a device to Rockwell Automation, be sure to remove all fluid residue. This
is particularly important if the fluid is a health hazard, e.g. flammable, toxic, caustic,
carcinogenic, etc.
Do not return a measuring device if you are not absolutely
certain that all traces of hazardous substances have been
removed, e.g. substances which have penetrated crevices
or diffused through plastic.

Installation instructions
Figure 3 Installing Bulletin 839E (example). Sensor length L is completely immersed in the flow
profile.
Mounting instructions:
• Any orientation
• The on-site display can be rotated electronically 180° — see “Operation” section.
• The housing can be rotated up to 310° for optimal readability and ease of wiring.
• Minimum sensor immersion length: L ≥ 10 mm (0.4 in.)
• The sensor tip should not touch the pipe wall.
• If used in a vertical pipe, the flow should be ascending.
• For a horizontal pipe, install sensor from top if pipe is completely filled with medium.
Otherwise, install sensor from side to ensure complete length of sensor is in the medium.
Do not turn the device into the process connection thread
at the housing. Always install the device at the
hexagonal-head bolt (refer to Figure 3, detail 1). Use a
suitable open-ended wrench for this task.
Note!
For correct flow measurement, the complete length of the sensor must be immersed in the
fully developed flow profile.

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.
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).
• The onsite display can be rotated electronically 180°, see “Onsite operation” section.
• The upper housing section can be rotated mechanically up to 310°.

Wiring
• The sensor tip should be completely
surrounded by medium.
• Position the sensor tip in the area of
maximum fluid velocity (pipe center).
• Minimum sensor immersion length:
L1 ±10 mm.
Orientation:
• For horizontal pipes: lateral installation.
Note!
Installation from above (see Figure 4) only if
the pipe is completely filled with medium
during operation.
• For vertical pipes: installation in the
ascending pipeline.
• Installation of 839E by min. 3° inclination,
because of self draining.
Figure 4 Installation conditions
Figure 5 Correct orientation
• Do not install in down
pipes open towards the
end.
• The sensor tip should
never touch the pipe
wall.
