1.1 The standard for simple applications
PRODUCT FEATURES
1
The electromagnetic signal converter IFC 050
in various kinds of applications in the water industry but also in the food and beverage business.
The signal converter can be combined with the flow sensors OPTIFLUX 1000, 2000, 4000, 6000
and the WATERFLUX 3000. The output represents measured values for flow, mass and
conductivity.
IFC 050 is a perfect choice for measuring volumetric flow
IFC 050IFC 050
This low-cost signal converter has some specific features:
• An active pulse output for a simple system, like driving an electro-mechanical counter
• RS485 Modbus communication with a data processing system
• Extra insulation of the electronic device and housing for high performance in areas with
extreme humidity and chances for flooding
• Cost-effective flow measurement for a wide range of process conditions and still a very
acceptable degree of accuracy
1 Large graphic display with 4 magnet keys for operating the signal converter when the housing is closed
2 4 push buttons to operate the signal converter when the housing is open
3 Supply voltage: 100…230 VAC and 24 VDC

1.2 Options and variants
Modular signal converter concept with display
PRODUCT FEATURES
The modular concept gives the opportunity to
combine the IFC 050 with the flow sensors
OPTIFLUX 1000, OPTIFLUX 2000, OPTIFLUX 4000,
OPTIFLUX 6000 and the WATERFLUX 3000.
With respect to the housing versions, both a compact
and a remote design are available. The signal
converter for the compact version is directly
mounted under a 10° angle to the flow sensor for
easy reading of the display after rainfall or frost.
If the measuring point is difficult to access or if the
ambient conditions like temperature effects and
vibration prevent the use of the compact version, a
remote signal converter with a wall housing is
available.
1
Remote version in wall housing with display
Remote version in wall housing without display
A signal cable is used to connect the flow sensor to
the signal converter for power supply and signal
processing.
The same electronic unit can be used in both
(Compact + Wall) versions without configuration.
A blind version is the perfect option in a situation
where the display is not required and the menu will
be approached once a time.
A separate display can be easily connected to the
electronic unit to enter the menu. This tool will be
provided as a spare part.

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
IFC 050
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.

Ambient temperature Depending on the version and combination of outputs.
It is a good idea to protect the converter from external heat sources such as direct
sunlight as higher temperatures reduce the life cycle of all electronic components.
