System description

ECOFLUX electromagnetic 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 10 - 150 /

3

/8” - 6” Q

can be set as a function of the meter size:

100%

= 0.1 - 760 m3/hr = 0.4 - 3350 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

ECOFLUX electromagnetic flowmeters are designed solely for measuring the volumetric flowrate
of electrically conductive, liquid process products.

Flowmeters with the ECOFLUX primary head are not certified for use in hazardous locations.
Other flowmeter 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 ECOFLUX 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

• 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 20-50 Hz with the IFC 010 K

and 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.

• 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.

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.

Separate primary head IFS 1000 F with terminal box

• A functional ground FE must always be connected.

• Signal converters with a field power supply of > 125 mA / > 60 V for the primary heads

should not be operated with the IFS 1000 F.

Compact systems

pply 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 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 IFS 1000 F

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.
