System description
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 Q100% can be set as a function of the meter size:
ALTOFLUX M900:
DN 10 - 300 / 3/8” - 12” Q100% = 0.1 - 3050 m3/hr = 0.37 – 13 440 US GPM
ALTOFLUX 3080 K:
DN 10 - 300 / 3/8” - 12” Q100% = 0.1 - 3050 m3/hr = 0.37 – 13 440 US GPM
This is equivalent to a flow velocity of 0.3 - 12 m/s, or 1 – 40 ft/s.
Product liability and warranty
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.

must be approximately horizontal in a
horizontal pipe run.
Yterminal 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.

Installation and operating instruction ALTOFLUX M900 and 3080 K 5
• 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:
Highest point of pipe run Downpipe over 5 m (16 ft) length
(Air bubbles collect in measuring Install air valve ✇downstream of
tube - faulty measurements!) flowmeter.
Pumps
Open feed or discharge Never install flowmeter on pump suction side.
Install meter in low section of pipe.

Preferred
locations

Install in slightly ascending pipe section. If
not possible, assure adequate velocity to
prevent air, gas or vapor from collecting in
uppper part of flow tube.

7 Grounding
• 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.
ALTOFLUX M900 separate primary head with terminal box
• An FE functional ground must always be connected.
• Signal converter with field power supply > 125 mA / 60 V a PE protective conductor must be
connected to the primary head, because of the higher field current from the signal converter. See
grounding diagrams below.
ALTOFLUX 3080 K compact systems
Supply power > 50 V AC
• Grounding is via the PE protective ground conductor incorporated in the power supply cable,
see also Section “Connection to power” in the installation and operating instructions for the signal
converter.
• EXCEPTION: Do not connect up the PE protective ground conductor in the terminal box
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
• Protective separation (PELV) must be ensured (VDE 0100 / VDE 0106 or IEC 364 / IEC 536 or
equivalent national regulations).
• An FE functional ground conductor must be connected for measurement reasons.

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 Q100% and the
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.
