Function and system design
Measuring principle Following Faraday's law of magnetic induction, a voltage is induced in a conductor moving through a
magnetic field.
In the electromagnetic measuring principle, the flowing medium is the moving conductor.
The voltage induced is proportional to the flow velocity and is supplied to the amplifier by means of
two measuring electrodes. The flow volume is calculated by means of the pipe cross-sectional area.
The DC magnetic field is created through a switched direct current of alternating polarity.

Q = A · v

Measuring system The measuring system consists of a transmitter and a sensor.
Two versions are available:
• Compact version: Transmitter and sensor form a mechanical unit.
• Remote version: Sensor is mounted separate from the transmitter.
Transmitter:
• Promag 10 (key operation, two-line, unilluminated display)
Sensor:
• Promag W, DN 25 to 2000 (1 to 78")

Potential equalization
!
Note!
The measuring system must be included in the potential equalization.
Perfect measurement is only ensured when the fluid and the sensor have the same electrical potential.
This is ensured by the reference electrode integrated in the sensor as standard.
The following should also be taken into consideration for potential equalization:
• Internal grounding concepts in the company
• Operating conditions, such as the material/grounding of the pipes (see table)
Standard situation
Operating conditions Potential equalization
When using the measuring device in a:
• Metal, grounded pipe
Potential equalization takes place via the ground terminal
of the transmitter.
Note!
!
When installing in metal pipes, we recommend you connect
the ground terminal of the transmitter housing with the
piping.

Operating conditions Potential equalization
When using the measuring device in a:
• Metal pipe that is not grounded
This connection method also applies in situations where:
• Customary potential equalization cannot be ensured.
• Excessively high equalizing currents can be expected.
Both sensor flanges are connected to the pipe flange by
means of a ground cable (copper wire, at least 6 mm² /
0.0093 in²) and grounded. Connect the transmitter or
sensor connection housing, as applicable, to ground
potential by means of the ground terminal provided for the
purpose.
Ground cable installation depends on the nominal
diameter:
•DN 300 (12"): The ground cable is mounted directly on
the conductive flange coating with the flange screws.
•DN 350 (14"): The ground cable is mounted directly on
the metal transport bracket.
Note!
!
The ground cable for flange-to-flange connections can be
ordered separately as an accessory from Endress+Hauser.

When using the measuring device in a:
• Plastic pipe
• Pipe with insulating lining
This connection method also applies in situations where:
• Customary potential equalization cannot be ensured.
• Excessively high equalizing currents can be expected.
Potential equalization takes place using additional ground
disks, which are connected to the ground terminal via a
ground cable (copper wire, at least 6 mm² / 0.0093 in²).
When installing the ground disks, please comply with the
enclosed Installation Instructions.
When using the measuring device in a:
• Pipe with a cathodic protection unit
The device is installed potential-free in the pipe.
Only the two flanges of the pipe are connected with a
ground cable (copper wire, at least 6 mm² / 0.0093 in²).
Here, the ground cable is mounted directly on the
conductive flange coating with flange screws.
Note the following when installing:
• The applicable regulations regarding potential-free
installation must be observed.
•There should be no electrically conductive connection
between the pipe and the device.
• The mounting material must withstand the applicable
torques.

Operation in zones of severe electrical interference
The measuring device complies with the general safety requirements in accordance with EN 61010-1,
the EMC requirements of IEC/EN 61326 and NAMUR Recommendation NE 21.
Note!
Grounding is by means of the ground terminals provided for the purpose inside the connection
housing.
Ensure that the stripped and twisted lengths of cable shield to the ground terminal are as short as
possible.

Installations
Mounting location Entrained air or gas bubble formation in the measuring tube can result in an increase in measuring
errors.
Avoid the following installation locations in the pipe:
• Highest point of a pipeline. Risk of air accumulating!
• Directly upstream from a free pipe outlet in a vertical pipeline.

Installation of the sensor after a control valve is not recommended
1 Control valve
Installation of pumps
Sensors may not be installed on the pump suction side. This precaution is to avoid low pressure and the
consequent risk of damage to the lining of the measuring tube. Information on the pressure tightness
of the measuring tube lining → 21, Section "Pressure tightness".
Pulsation dampers may be needed when using piston pumps, piston diaphragm pumps or hose pumps.
Information on the shock and vibration resistance of the measuring system → 17, Section "Shock and
vibration resistance".

Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration.
The empty pipe detection function (EPD) provides additional security in detecting empty or partially
filled pipes.
Note!
Risk of solids accumulating. Do not install the sensor at the lowest point in the drain. It is advisable to
install a cleaning valve.
A0003204
Installation with partially filled pipes
Down pipes
Install a siphon or a vent valve downstream of the sensor in down pipes h 5 m (16.4 ft). This
precaution is to avoid low pressure and the consequent risk of damage to the lining of the measuring
tube. This measure also prevents the liquid current stopping in the pipe which could cause air locks.
Information on the pressure tightness of the measuring tube lining → 21, Section "Pressure
tightness".

Orientation An optimum orientation helps avoid gas and air accumulations and deposits in the measuring tube.
However, the measuring device also offers the additional function of empty pipe detection (EPD) for
detecting partially filled measuring tubes or if outgassing fluids or fluctuating operating pressures are
present.
Vertical orientation
This is the ideal orientation for self-emptying piping systems and for use in conjunction with empty
pipe detection.
