PRODUCT FEATURES 1
1.1 Solution for the water and wastewater industry
The IFC 070 electromagnetic signal converter is designed for use in water industry such as
potable water distribution networks, for revenue billing and for water abstraction. It is battery
powered, making it especially suitable for applications where no power connection is available
and provides certainty in case of power failure. Optional a GSM and data logger module is
available for the remote transmission of measurement data and status information.

There is an increased demand by utilities for
remote reading. Often water meters are
installed at remote locations in the
distribution network or below the ground for
example in busy city centers. The IFC 070 can
be supplied with a state-of-the-art data logger
and GSM modem. The stored data is
tranmitted (for example once a day) by SMS
and can be forwarded to the customer's
management system.

The IFC 070 signal converter can be supplied
in either compact or remote design. In case of
a remote design, the converter can be
installed on the wall or on a pipe. The
functionality of the compact and remote
versions is identical.

1.3 Measuring principle
An electrically conductive fluid flows inside an electrically insulating 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. The signal voltage is quite small (typically 1 mV at v = 3 m/s / 10 ft/s and
field coil power of 1 W). Finally, a signal converter is used to amplify the signal voltage, filter it
(separate from noise) and convert it into signals for totalising, recording and output processing.
