System description
PROFIFLUX electromagnetic flowmeters are precision measuring instruments designed for the linear flow measurement of process liquids.
1
The process liquids must be electrically conductive: 05 µS/cm (10 µS/cm for DN 2.5/
/10”)
20 µS/cm for demineralized cold water
The full-scale range Q DN 2.5 - 100 /
1
/10” - 4” Q
can be set as a function of the meter size:
100%
= 0.01 - 340 m3/hr = 0.03 - 1500 US Gal/min
100%
This is equivalent to a flow velocity of 0.3 - 12 m/s, or 1 - 40 ft/s.
Product liability and warranty
PROFIFLUX electromagnetic flowmeters are designed solely for measuring the volumetric flowrate of electrically conductive, liquid process products.
Special codes and regulations apply to their use in hazardous locations, and these are referred to in the special “Ex” installation and operating instructions (supplied only with hazardous-duty equipment).
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 PROFIFLUX 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.
Standards and approvals
Please refer to the installation and operating instructions for the signal converter.

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: 20-500 Hz, ran dom / 2 g rms / 30 minutes / x, y, z directions.
Do not expose to direct sunlight,
fit a sunshade if necessary, not included with flowmeter, to be provided by customer.
4
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 x 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 downsteam of the flowmeter or upsteam and downstream of the flowmeter.
2 Suggestions for installation
To avoid measuring errors due to gas/air inclusion or to pipe runing empty please observe the following:
Highest point of pipe run
(Air bubbles collect in measuring tube - faulty measurements!)
Preferred locations
Downpipe
”Zero” flow velocity. Line drained. Faulty measurements!
Horizontal pipe run
Install in slightly ascending pipe section. If not possible, assure adequate velocity to prevent air, gas or vapor from collecting in upper part of flow tube.
Open feed or discharge
Install meter in low section of pipe.
Downpipe over 5 m (16 ft) length
Install air valve X downstream of flowmeter.
Long pipeline Always install control and shutoff valves
downstream of flowmeter.
Pumps Never install flowmeter on pump suction side.

High-temperature pipelines
Where process temperatures exceed 100 °C/212 °F, provide for facilities to compensate for longitudinal expansion on heat-up of the pipeline. For short pipelines use resilient gaskets and for long pipelines install flexible pipe elements (e.g. elbows).

7. Grounding
Warning: 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.
IFS 5000 F separate primary head with terminal box
A functional ground FE must always be connected.
Signal converters with a field power supply of > 125 mA / > 60 V:
IFS 5000 F primary head: because of the higher field current from the signal converter, a PE protective conductor must be connected to the primary head, see grounding diagrams below.

Compact systems

Su
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 su
pply 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 Q
100%
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.

• 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 envi-
ronment 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 such dangerous 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.
