ALTOFLUX electromagnetic flowmeters are precision measuring instruments designed for the
linear flow measurement of process liquids.
The process liquids must be electrically conductive: ≥ 20 µS/cm
The full-scale range Q
ALTOFLUX M900:
DN 10 - 300 /
ALTOFLUX 3080 K:
DN 10 - 300 /
This is equivalent to a flow velocity of 0.3 - 12 m/s, or 1 – 40 ft/s.

/8” - 12” Q
can be set as a function of the meter size:

ALTOFLUX electromagnetic flowmeters are designed solely for measuring the volumetric
flowrate of electrically conductive, liquid process products.
Flowmeters with ALTOFLUX primary heads are not certified for use in hazardous locations.
Other flowmeters series are available for such applications.
Responsibility as to suitability and intended use of these electromagnetic flowmeters rests solely
with the operator.
Improper installation and operation of the flowmeters (systems) may lead to loss of warranty.
In addition, the ”General conditions of sale” forming the basis of the purchase contract are
applicable.
If ALTOFLUX flowmeters need to be returned to Krohne, please note the information given on
the last-but-one page of this manual. Krohne regret that they cannot repair or check your
flowmeter(s) unless accompanied by the completed form sheet.

Refer to Section 11 “Limits” for operating pressure and vacuum load based on flange
standards and type of tube liner.

avoid moisture and sunlight.
Transport - 5 to +50 °C (- 4 to +140 °F), (Neoprene liner)

• Location and position as required,
but electrode axis
X – • – • – • – X
must be approximately horizontal in a
horizontal pipe run.
Y terminal box or converter housing
• Measuring tube must be completetly filled at all times.
• Direction of flow is arbitrary. Arrow on flowmeter can normally be ignored. For exceptions,
refer to Section “Factory settings” in the installation and operating instructions for the signal
converter.
• Stud bolts and nuts: to fit, make sure there is sufficient room next to the pipe flanges.
• Vibration: support the pipeline on both sides of the compact flowmeter. Level of vibration in
conformity with IEC 068-2-34: below 2.2g for compact flowmeters in the frequency range of
20-150 Hz with the IFC 090 K.
• Do not expose to direct sunlight, fit a sunshade if necessary, not included with flowmeter,
to be provided by customer.
• Large meter sizes (≥ DN 200 / ≥ 8”), use adapter pipes to allow axial shifting of the
counterflanges and to facilitate installation.
• Strong electromagnetic fields, avoid in vicinity of flowmeter
• Straight inlet run minimum of 5 × DN and outlet run minimum of 2 × DN,
(DN = meter size), measured from the electrode axis.

• Vortex and corkscrew flow: increase length of inlet and outlet runs or install flow
conditioners.
• Mixing different process liquids: install flowmeter upstream of mixing point or at an
adequate distance downstream (minimum of 30 × DN), otherwise display may be unsteady.
• Plastic pipes and internally coated metal pipelines: grounding rings required, see Section 7
“Grounding”.
• Insulated pipeline: do not insulate flowmeter.
• Zero setting not necessary. To check, it should be possible to set “zero” flow velocity in the
completely filled measuring tube. Shutoff valves should therefore be provided either
downstream of the flowmeter or upstream and downstream of the flowmeter.
2 Suggestions for installation
To avoid measuring errors due to gas/air inclusion or to pipe running empty, please observe the
following:

All flowmeters must be properly grounded to avoid personnel shock hazard.
•
The ground conductor should not transmit any interference voltages, therefore do not ground any
other electrical devices together with this conductor.

Grounding is via the
see also Section “Connection to power” in the installation and operating instructions for the signal
converter.
•
EXCEPTION:
if e.g. compact units are operated in the proximity of electric furnaces, electrolysis plants, etc.,
and large potential differences occur in the pipeline system. An FE functional ground must
simultaneously take over the function of the protective conductor (combined protective/functional
ground). Refer to appropriate national codes for specific requirements for this type of installation,
which may require the addition of a ground fault detection circuit interrupter.
Power supply 24 V AC or DC

8 Replacement of the separate primary head
Switch off power source before commencing work !
1) Note down terminal assignment before dismantling the “old” primary head.
2) Install the new primary head as described in the supplied installation instructions.
3) Make electrical connection at the signal converter as described in the installation and
operating instructions for the signal converter.
4) Specific calibration data are defined during factory calibration for each primary head, which
are indicated on the instrument nameplate.
This includes the primary constant GK and the magnetic field frequency.
These data need to be reset in the signal converter.
5) If the size of primary head is also different from the old one, the full-scale range Q
meter size will need to be reset.
6) After resetting the signal converter, carry out a zero point check.
7) If necessary, reset the internal electronic totalizer of the signal converter.

If you need to return flowmeters for testing or repair to KROHNE
Your electromagnetic flowmeter
• has been carefully manufactured and
tested by a company with ISO 9001
certification
• and volumetrically calibrated in one of the
world’s most accurate test rigs.
If installed and operated in accordance with
these operating instructions, your flowmeter
will rarely present any problems.
Should you nevertheless need to return a
flowmeter for checkout or repair, please pay
strict attention to the following points:
Due to statutory regulations concerning
protection of the environment and the health
and safety of our personnel, Krohne may only
handle, test and repair returned flowmeters
that have been in contact with liquids if it is
possible to do so without risk to personnel
and environment. This means that Krohne
can only service your flowmeter if it is
accompanied by a certificate in line with the
following model confirming that the flowmeter is
safe to handle.
If the flowmeter has been operated with toxic,
caustic, flammable or water-endangering
liquids, you are kindly requested
• to check and ensure, if necessary by rinsing
or neutralizing, that all cavities in the
flowmeter are free from suchdangerous
substances.
(Directions on how you can find out whether
the primary head has to be opened and then
flushed out or neutralized are obtainable
from Krohne on request.)
• to enclose a certificate with the flowmeter
confirming that the flowmeter is safe to
handle and stating the liquid used.
KROHNE regret that they cannot service your
flowmeter unless accompanied by such a
certificate.
