1 PRODUCT FEATURES
1.1 The power of independence
The IFC 070 is a battery powered electromagnetic signal converter designed for use in
combination with the WATERFLUX 3000 sensor. It is ideal for remote locations in the water
industry where no power connection is available and provides certainty in case of power failure.
The strengths of the WATERFLUX 3070 lies in its unique flow sensor construction with a
rectangular and reduced cross section and its efficient coil construction. The coils provide a
stronger and more homogenous magnetic field, leading to an improved signal to noise ratio. The
measurement is therefore independent of the flow profile and measurements are very stable.
This results in a very good low flow performance.
Because of the unique WATERFLUX flow sensor design, whereby the mean flow velocity and flow
profile are optimised within the rectangular and reduced cross section, the additional
uncertainty for upstream disturbances is drastically reduced. The water meter can be installed
directly behind an elbow or reducer in the pipe without straight inlet or outlet lengths.
A substantial reduction of inlet and outlet sections means smaller measurement pits.
Another major benefit of the rectangular sensor construction is the very low power consumption
of the signal converter. It has a long battery lifetime up to 15 years with two internal batteries
and 20 years with an external battery pack.

can be installed on a wall or on a pipe.
The functionality of the compact and the
remote version is identical.

The WATERFLUX 3070 can be operated
using 1 or 2 lithium monocell batteries
or an external battery pack. The meter
reading is saved internally, which
ensures that there is no loss of data
when changing the batteries.
The signal converter has a very low
power consumption because of its
rectangular sensor construction.
With two internal batteries it has a
battery lifetime up to 15 years.

The flow sensor (IP68) is suitable for
submersion in flooded measurement
chambers. With its robust construction
it can also be buried underground. This
can be a major cost saving as it
eliminates the need for a measurement
chamber. To protect the flow sensor a
special coating can be ordered as an
option. The remote version has an IP68
stainless steel connection box.

1.3 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
in which:
v = mean flow velocity
k = factor correcting for geometry
B = magnetic field strength
D = inner diameter of flow meter
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 totalising, recording and output processing.

The minimal height of the measuring tube decreases the distance between the field coils (4),
resulting in a stronger and more homogeneous magnetic field (3). In addition, the mean flow
velocity v increases due to the rectangular and reduced cross section. The large electrode
spacing (D) and the increased flow velocity results in a higher magnetic signal voltage, also in
the presence of a low flow rate.
