System description
Electromagnetic flowmeters with the IFC 020 signal converter are precision instruments designed
for linear flow measurement of liquid products.
The process liquids must be electrically conductive: ≥ 5 µS/cm
(for cold demineralized water ≥ 20 µS/cm).
The full-scale range Q100% can be set as a function of the meter size:
Q100% = 0.0060 - 86 860 m3/hr = 0.03 - 156.672 US Gal/min
This is equivalent to a flow velocity of 0.3 - 12 m/s or 1 - 40 ft/s.
Product liability and warranty
The electromagnetic flowmeters with the IFC 020 signal converter are designed solely for
measuring the volumetric flowrate of electrically conductive, liquid process products.
These flowmeters are not certified for use in hazardous areas. 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 flowmeters need to be returned to Krohne, please note the information given on the last-but-one
page of these Instructions. Krohne regrets that it cannot repair or check your flowmeter(s) unless
accompanied by the completed form sheet.
CE / EMC / Standards / Approvals
• Electromagnetic flowmeters with the IFC 020 signal converter meet the protection requirements
of Directive 89/336/EEC in conjunction with EN 50081-1 (1992) and EN 50082-2 (1995),
as well as Directives 73/23/EEC and 93/68/EEC in conjunction with EN 61010-1, and bear the
CE marking.

•
•
•
•
•
•
Location
Electrical connection in accordance with VDE 0100 ”Regulations governing heavy-current
installations with line voltages up to 1000 V” or equivalent national regulations.
Do not cross or loop cables inside the terminal compartment.
Use separate cable entries (see below) for power supply, field current cables, signal lines,
outputs and inputs.
Protect flowmeters or switchgear cabinets with built-in devices from direct sunlight.
Fit a sunshade if necessary.
When installed in switchgear cabinets, signal converters must be adequately cooled,
e.g. use fans or heat exchangers.
Do not expose signal converters to intense vibration.
1.1.2
•
PLEASE NOTE !
Only for separate systems/signal converters (F- and E versions)
Keep distance between primary head and signal converter as short as possible.
Refer to Sect. 1.3.4 for maximum permissible length of signal and field current cables.
Use the supplied Krohne signal cable A (Type DS), standard length 10 m (33 ft).
Always calibrate primary head and signal converter together. Therefore, when installing,
ensure primary constant GK is identical; refer to instrument nameplate for the primary
head. If the GK is not identical, set the signal converter to the GK of the primary head.
Refer also to Section 4.
Dimensions of signal converter; refer to Section 10.4.
1.1.3 Cable entries (K- and F- versions)
Number of cable entries: 2 for the compact flowmeters

A)
PG 13.5 cable entries
These cable entries may only be used for flexible electrical cables if the relevant electrical
regulations so allow, e.g. National Electric Code (NEC).
Do not fix rigid metal conduits (IMC) or flexible plastic conduits to the PG 13.5 cable entries, refer
to “Point B/C” below (1/2” NPT or PF adapters).
B)
1/2“ NPT adapters
C) 1/2“ PF adapters
For most North American systems the regulations require that electrical conductors be laid in
conduits, particularly where power voltages > 100 V AC are concerned.
In such cases, use the 1/2” NPT or 1/2” PF adapters to which flexible plastic conduits can be
screwed. Do not use rigid metal conduits (IMC) !
Lay conduits such that no moisture can penetrate into the converter housing.
Should there be risk of any condensation water forming, fill the cross-section of the conduit
around the cables at these adapters with a suitable sealing compound.

Start-up
3.1
Power- on and measurement
•
Before powering the system, please check that it has been correctly installed according
to Sect. 1 and 2.
•
The flowmeter is delivered ready for operational use. All operating data have
been factory set in accordance with your specifications.
Please refer to Sect. 3.2 “factory settings”.
•
Power the unit, and the flowmeter will immediately start process flow measurement.
•
When powered, the display shows in succession: START UP and READY.
This is followed by display of the current flow rate and/or the current totalizer count
on either a continuous or alternating basis, depending on the setting under Fct. 1.04.
Refer to Sect. 4 and 5 for operator control of the “display version”.
•
3.2
Factory setting
All operating data are factory set according to your order specifications.
If you have not made any particular specifications at the time of ordering, the instruments will be
delivered with the standard parameters and functions listed in the Table below.
To facilitate easy and rapid initial start-up, current output and pulse output are set to process flow
measurement in “2 flow directions”, so that the current flowrate is displayed and the volumetric
flow counted independent of the flow direction. On instruments equipped with a display, measured
values may possibly be shown with a “ – ” sign.
This factory setting for the current and pulse outputs may possibly lead to measuring errors,
particularly in the case of volume flow counting:
for example, if pumps are switched off and a “backflow” occurs which is not within the range of the
low-flow cutoff (SMU), or if separate displays and counts are required for both flow directions.
To avoid faulty measurements, therefore, it may be necessary to change the factory setting of
some or all of the following functions:
– low-flow cutoff SMU, Fct. 1.03, Sect. 5.3
– current output I, Fct. 1.05, Sect. 5.6
– pulse output P, Fct. 1.06, Sect. 5.7
– display (option), Fct. 1.04, Sect. 5.4
Operation see Section 4 and 5.

HART ® interface
The HART interface is a smart interface, in other words a communication signal superimposed on
the current output. All functions and parameters can be accessed via this interface.
The following HART features are supported:
• point-to-point connection
• multidrop (up to 15 HART devices)
The burst mode is not normally used. Further information about HART is available from the HART
Communication Foundation, of which Krohne is a member.

HART operating tools / Device Description (DD)
The IFC 020 can be operated either via its local operator interface or by means of the HART
communicator or the CONFIG program. Both operating tools are available from KROHNE.
Operator control by means of the HART communicator requires a device description (DD) which
we can load for you into the communicator. We can, of course, also load the DDs of all
manufacturers who have filed their DDs with the HART Communication Foundation. If you wish to
use the IFC 020 in your operating tool, for example, please ask for the description of the HART
command used so that you can address the complete IFC 020 functionality via HART.

Operator control of the signal converter for the new settings, see Sect. 4 and 5
To change settings
• Fct. 3.02 FIELD FREQ. (change magnetic field frequency)
– Stroke frequency less than 80 strokes/min (at max. pump lift): do not change setting.
– Stroke frequency 80 - 200 strokes/min (at max. pump lift): change setting to 1/2,
only practical with IFM 5020 K and IFS 5000 F (DN 2.5-100 / 1/10”-4”)
and IFM 4020 K and F IFS 4000 F (DN 10, 15, 50-100 / 1/10”, 1/2”, 2”-4”),
Please consult factory where other types and meter sizes are concerned.
– Please note: given stroke frequencies close to the tripping point of 80 strokes/min, additional
measuring errors of approx. ± 0.5% of the measured value may occasionally occur.
• Fct. 3.06 APPLICAT. (adjust overload point of the A/D converter to the application)
Change setting to “PULSATING”.
• Fct. 1.04 DISP. FLOW (change display presentation of flow)
Change setting to “BARGRAPH” to allow better assessment of display unsteadiness.
• Fct. 1.02 TIMECONST. (change time constant)
– Set to “ALL” and time (t) in seconds.

Unsteady display and outputs
6.6
Unsteady display and outputs can occur in connection with
– high solids contents,
– non-homogeneity,
– poor blending, or
– chemical reactions still in progress in the process liquid.
If, in addition, flow is also pulsating due to the use of diaphragm or reciprocating pumps,
refer to Sect. 6.4.

Measuring principle
The flowmeter is designed for electrically conductive fluids.
Measurement is based on Faraday’s law of induction, according to which a voltage is induced in
an electrically conductive body which passes through a magnetic field. The following expression
is applicable to the voltage.:
U=KxBxvxD
where:
U = induced voltage
K = an instrument constant
B = magnetic field strength
v = mean velocity
D = pipe diameter
Thus the induced voltage is proportional to the mean flow
velocity, when the field strength is constant.
U
B
D
U
v
Inside the electromagnetic flowmeter, the fluid passes
through a magnetic field applied perpendicular to the
direction of flow. An electric voltage is induced by the
movement of the fluid (which must have a minimum
electrical conductivity). This is proportional to the mean
flow velocity and thus to the volume of flow. The induced
voltage signal is picked up by two electrodes which are in
conductive contact with the fluid and is transmitted to a
signal converter for a standardized output signal.
This method of measurement offers the following advantages:
1. No pressure loss through pipe constriction or protruding parts.
2. Since the magnetic field passes through the entire flow area, the signal represents a mean
value over the pipe cross-section; therefore, only relatively short straight inlet pipes
5 x DN from the electrode axis are required upstream of the primary head.
3. Only the pipe liner and the electrodes are in contact with the fluid.
4. Already the original signal produced is an electrical voltage which is an exact linear function
of the mean flow velocity.
5. Measurement is independent of the flow profile and other properties of the fluid.
The magnetic field of the primary head is generated by a square wave current fed from signal
converter to the field coils.
This field current alternates between positive and negative values. Alternate positive and negative
flowrate-proportional signal voltages are generated at the same frequency by the effect of the
magnetic field, which is proportional to the current. The positive and negative voltages at the
primary head electrodes are subtracted from one another in the signal converter. Subtraction
always takes place when the field current has reached its stationary value, so that constant
interference voltages or external or fault voltages changing slowly in relation to the measuring
cycle are suppressed. Power line interference voltages coupled in the primary head or in the
connecting cables are similarly suppressed.

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.
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
•
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
•
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
