Principle of Operation
The Faraday Laws of Induction, which state that a voltage is generated
in a conductor when it moves through a magnetic field, form the basis for
the electromagnetic flowmeter measurements.
This measurement principle is applied to a conductive fluid which flows
in a pipe in which a magnetic field is generated perpendicular to the flow
direction (see Schematic).
The voltage which is induced in the fluid is measured at two electrodes
located diametrically opposite to each other. This signal voltage U
E
is
proportional to the magnetic induction B, the electrode spacing D and
the average fluid velocity v.
Since the magnetic induction B and the electrode spacing D are constant
values the signal voltage U
E
is proportional to the average flow velocity v.
The equation for calculating the volumetric flowrate shows that the signal
voltage U
E
is linear and proportional to the volumetric flowrate.
The induced signal voltage is converted into scaled, analog and digital
output signals in the converter.

Installation Requirements and Grounding
In- and Outlet Pipe Sections
The metering principle is independent of the flow profile as long as stand
ing eddies do not extend into the metering section, such as may occur
after double elbows, tangential inflow or partially open gate valves up
stream of the flowmeter. It is recommended that flow control devices be
installed downstream from the flowmeter primary. It is essential to assure
that the meter tube is always completely filled with fluid.
Our experience indicates that in most installations, straight inlet sections
3 x D long and straight outlet sections 2 x D long are sufficient.
For test stands the reference conditions in EN 29104 are to be main
tained. For certified instruments, there are special in and outlet length
requirements (see Page 7).
Installation in Larger Size Pipelines
The flowmeter primary can readily be installed in larger pipeline sizes by
utilizing reducers (e.g. flanged reducers DIN 2616). The pressure drop
which results from the reduction can be determined from the Nomograph
Fig. 4. The pressure drop is determined in the following manner:
1.
2.
3.
Calculate the diameter ratio d/D.
Determine the flow velocity from the Flow Range Nomograph
Fig. 5 .
Read the pressure drop on the Y Axis in Fig. 4.
Flanged reducer
Electrode Axis
The meter can be installed in vertical, horizontal or sloped pipelines. The
electrode axis should be horizontal, if at all possible. A vertical electrode
axis orientation should be avoided. An ideal installation is shown in Fig. 3 .

Grounding
The grounding of the flowmeter primary is essential not only for safety
reasons, but also of importance to assure trouble free operation of the
electromagnetic flowmeter. The ground screws on the flowmeter primary
are to be brought to ground potential. For technical reasons this potential
should be identical to the potential of the metering fluid, if possible.
For plastic or insulated lined pipelines the fluid is grounded by installing
ground plates. When there are stray potentials present in the pipeline, a
ground plate is recommended on both ends of the meter primary.
For flowmeter primaries with hard or soft rubber liners, sizes DN 125/5”
and larger, a conductive element is incorporated in the liner. This assures
that the fluid is grounded.
To comply with the EMC and Low Voltage Regulations the connection
box/converter must be grounded in addition to the meter tube of the
flowmeter primary. The green/yellow cable, included with the shipment,
should be used to make this connection. Connection examples are
shown in the Section „Interconnection Diagrams“ starting on Page 37.
