System description

VARIFLUXelectromagnetic flowmeters are precision measuring instruments designed for the
linear flow measurement of process liquids.

The process liquids must be electrically conductive: ≥ 05 µS/cm

≥ 20 µS/cm for demineralized cold water

The full-scale range Q
DN 2.5 - 80 /

1

/10” - 3” Q

can be set as a function of the meter size:

100%

= 0.01 - 220 m3/hr = 0.03 - 960 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

VARIFLUX 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 VARIFLUX 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, random / 2g runs / 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.

• 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.

• 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.

• A functional ground FE must always be connected.

• Signal converters with a field power supply of > 125 mA / > 60 V:

Because of the higher field current from the signal converter, a PE protective conductor must
be connected to the IFS 6000 F primary head, see grounding diagrams.

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

8.1 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.

8.2 Replacement of O-ring gaskets with adapters

– Unscrew union nuts.

Caution: keep hold of the flowmeter

to prevent it from dropping out of the pipeline.
– Remove the flowmeters from the pipeline.
– Remove O-rings (gaskets D1, see grounding

diagram in Sect. 7) from the adapter grooves.
– Apply grease to new gaskets D1

(Paraliq GTE 703, Silubin or Similar).
– Insert O-rings into the adapters.
– Slide the flowmeter between the adapters.
– Tighten union nuts down to metal stop.

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 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.
