1.1 The all-round solution
The IFC 100
IFC 100 electromagnetic signal converter combines an attractive price with a wide range of
IFC 100IFC 100
features and benefits including an excellent measuring accuracy.
The signal converter is compatible with almost any flow sensor in the OPTIFLUX and
WATERFLUX range.
The signal converter supplies the current required by two field coils to generate a magnetic field.
It converts the flow proportional signal voltage into digital values and filters out electrical noise
and interference signals. From the filtered signal, the flow velocity, the volume flow and the
mass flow are calculated.
The IFC 100
IFC 100 signal converter provides a large variety of flowmeter and process diagnostic
IFC 100IFC 100
functions guaranteeing reliable measurements. Detection of deposits or coating on the
electrodes, temperature and conductivity changes in the medium, gas bubbles or solids, and an
empty pipe are good examples of process diagnostics functions.
The flow velocity and volume can be read from the display or in analogue form via the current
output (4...20 mA) as well as by frequency, pulse and status outputs. Measuring values and
diagnostic information can be transmitted via the HART

1.2 Options and variants
Compact or remote wall-mounted housing
(signal converter in wall-mounted
aluminium housing)
PRODUCT FEATURES
For an optimal reading of the display, the compact
variant comes in a 0° and a 45° version.
The signal converter can be rotated in 90°
increments to suit different installation positions.
The compact 0° version is designed for flowmeters
in vertical pipelines, the compact 45° version for
horizontal installations.
The wall mounted signal converter can be installed
remotely for locations where the sensor is difficult to
access, or ambient temperature conditions or
vibrations prevent a compact variant.

Variant for use in hazardous areas
(Compact version as 0° version)
The IFC 100 signal converter is available in a variant
suitable for hazardous areas with approvals to ATEX,
IECEx, FM, CSA and NEPSI.

PRODUCT FEATURES
Stainless steel housing (option)
(signal converter in wall-mounted
stainless steel housing)
IFC 100
Whereas the standard housing material is
aluminium with a polyester topcoat, the IFC 100
optionally be ordered in a stainless steel housing.
The robust housing is suitable for many applications
in the food and beverage industry.
It is designed for environments where extreme
chemicals or aggressive cleaning are used.
The housing is dual rated to IP67/69 protection
category to resist wash down cleaning and no glass
is used for the display window.
The mounting angle for the compact housing and the
rounded edges in the wall-mount position prevent
dirt and water from building up on the surface.

Diagnostics of device and application
OPTICHECK tool for on-site verification
The primary focus of a user for a flowmeter is that it
delivers reliable measurements. To achieve this all
our electromagnetic flowmeters are calibrated
before leaving the factory.
In addition, the IFC 100
functions on the flow sensor, signal converter and
process, integrated in the signal converter.
Potential problems including gas bubbles, solids,
electrode corrosion, deposits on electrodes,
conductivity changes, empty pipe can be detected by
the diagnostics features.
The OPTICHECK provides an inline health check of the
device under test by an external tool.
When the tool is connected on site, it gathers measuring
data to ensure that the flowmeter performs within 1% of its
factory calibration.
IFC 100 provides a range diagnostic
IFC 100IFC 100
(Suitcase with OPTICHECK and all cables and
accesssories)

The baseline can be historic repair data from the factory or
on-site test results after performing a full verification.
A hard copy of the verification report can be printed for
every flowmeter. The verification data are digitally stored.

visit.

1.4 Measuring principle
An electrically conductive fluid flows inside an electrically insulated pipe through a magnetic
field. This magnetic field is generated by a current, flowing through a pair of field coils.
Inside of the fluid, a voltage U is generated:
U = v * k * B * D
U = v * k * B * D
U = v * k * B * DU = v * k * B * D
1
in which:
v = mean flow velocity
k = factor correcting for geometry
B = magnetic field strength
D = inner diameter of flowmeter
The signal voltage U is picked off by electrodes and is proportional to the mean flow velocity v
and thus the flow rate Q. A signal converter is used to amplify the signal voltage, filter it and
convert it into signals for totalizing, recording and output processing.

2.4 Measuring accuracy
Every electromagnetic flowmeter is calibrated by direct volume comparison. The wet calibration
validates the performance of the flowmeter under reference conditions against accuracy limits.
The accuracy limits of electromagnetic flowmeters are typically the result of the combined effect
of linearity, zero point stability and calibration uncertainty.
Reference conditions
• Medium: water
• Temperature: +5...+35°C / +41...+95°F
• Operating pressure: 0.1...5 barg / 1.5...72.5 psig
• Inlet section: ≥ 5 DN; outlet section: ≥ 2DN

INSTALLATION
3.1 Intended use
The electromagnetic flowmeters are designed exclusively to measure the flow and conductivity
of electrically conductive, liquid media.
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex
documentation.
If the device is not used according to the operating conditions (refer to chapter "Technical data"),
the intended protection could be affected.
This device is a Group 1, Class A device as specified within CISPR11:2009. It is intended for use in
industrial environment. There may be potential difficulties in ensuring electromagnetic
compatibility in other environments, due to conducted as well as radiated disturbances.
3.2 Installation specifications
The following precautions must be taken to ensure reliable installation.
•
Make sure that there is adequate space to the sides.
•
The device must not be heated by radiated heat (e.g. exposure to the sun) to an electronics
housing surface temperature above the maximum permissible ambient temperature. If it is
necessary to prevent damage from heat sources, a heat protection (e.g. sun shade) has to be
installed.
•
Signal converters installed in control cabinets require adequate cooling, e.g. by fan or heat
exchanger.
•
Do not expose the signal converter to intense vibrations. The measuring devices are tested
for a vibration level as described in the chapter "Technical data".
IFC 100
3.3 Mounting of the compact version
Turning the housing of the compact version is not permitted.
The signal converter is mounted directly on the flow sensor. For installation of the flowmeter,
please observe the instructions in the supplied product documentation for the flow sensor.

ELECTRICAL CONNECTIONS
4.1 Important notes on electrical connection
Electrical connection is carried out in conformity with the VDE 0100 directive "Regulations for
electrical power installations with line voltages up to 1000 V" or equivalent national regulations.
The device must be grounded in accordance with regulations in order to protect personnel
against electric shocks.
•
Use suitable cable entries for the various electrical cables.
•
The flow sensor and signal converter have been configured together at the factory. For this
reason, please connect the devices in pairs. Ensure that the flow sensor constant GK/GKL
(see nameplates) are identically set.
•
If delivered separately or when installing devices that were not configured together, set the
signal converter to the DN size and GK/GKL of the flow sensor.
4.2 Preparing the signal and field current cables
Assembly materials and tools are not part of the delivery. Use the assembly materials and tools
in compliance with the applicable occupational health and safety directives.
