Measuring principle
Following Faraday's law of magnetic induction, a voltage is induced in a conductor moving through a
magnetic field.
A0028962
Ue Induced voltage
B Magnetic induction (magnetic field)
L Electrode spacing
I Current
v Flow velocity
In the electromagnetic measuring principle, the flowing medium is the moving conductor. The
voltage induced (Ue) is proportional to the flow velocity (v) and is supplied to the amplifier by means
of two measuring electrodes. The flow volume (Q) is calculated via the pipe cross-section (A). The DC
magnetic field is created through a switched direct current of alternating polarity.
Formulae for calculation
• Induced voltage Ue = B · L · v
• Volume flow Q = A · v

Safety IT security
We only provide a warranty if the device is installed and used as described in the Operating
Instructions. The device is equipped with security mechanisms to protect it against any inadvertent
changes to the device settings.
IT security measures in line with operators' security standards and designed to provide additional
protection for the device and device data transfer must be implemented by the operators themselves.
Device-specific IT security
The device offers a range of specific functions to support protective measures on the operator's side.
These functions can be configured by the user and guarantee greater in-operation safety if used
correctly. An overview of the most important functions is provided in the following section.
Protecting access via hardware write protection
Write access to the device parameters via the local display or operating tool (e.g. FieldCare,
DeviceCare) can be disabled via a write protection switch (DIP switch on the motherboard). When
hardware write protection is enabled, only read access to the parameters is possible.
Hardware write protection is disabled when the device is delivered.
Protecting access via a password
Different passwords are available to protect write access to the device parameters or access to the
device via the WLAN interface.
• User-specific access code
Protect write access to the device parameters via the local display, Web browser or operating tool
(e.g. FieldCare, DeviceCare). Access authorization is clearly regulated through the use of a userspecific access code.
• WLAN passphrase
The network key protects a connection between an operating unit (e.g. notebook or tablet) and the
device via the WLAN interface which can be ordered as an option.
User-specific access code
Write access to the device parameters via the local display or operating tool (e.g. FieldCare,
DeviceCare) can be protected by the modifiable, user-specific access code.
Endress+Hauser 7
Proline Promag L 400
WLAN passphrase
A connection between an operating unit (e.g. notebook or tablet) and the device via the WLAN
interface which can be ordered as an option is protected by the network key. The WLAN
authentication of the network key complies with the IEEE 802.11 standard.
When the device is delivered, the network key is pre-defined depending on the device. It can be
changed via the WLAN settings submenu in the WLAN passphrase parameter.
General notes on the use of passwords
• The access code and network key supplied with the device should be changed during
commissioning.
• Follow the general rules for generating a secure password when defining and managing the access
code or network key.
• The user is responsible for the management and careful handling of the access code and network
key.
Access via fieldbus
When communicating via fieldbus, access to the device parameters can be restricted to "Read only"
access. The option can be changed in the Fieldbus writing access parameter.
This does not affect cyclic measured value transmission to the higher-order system, which is always
guaranteed.
For detailed information, see the "Description of Device Parameters" document pertaining to the
device → 89
Access via Web server
The device can be operated and configured via a Web browser with the integrated Web server. The
connection is via the service interface (CDI-RJ45) or the WLAN interface. For device versions with
the EtherNet/IP and PROFINET communication protocols, the connection can also be established via
the terminal connection for signal transmission with EtherNet/IP or PROFINET (RJ45 connector).
The Web server is enabled when the device is delivered. The Web server can be disabled if necessary
(e.g. after commissioning) via the Web server functionality parameter.
The device and status information can be hidden on the login page. This prevents unauthorized
access to the information.
For detailed information, see the "Description of Device Parameters" document pertaining to the
device → 89

Potential equalization Requirements
Please consider the following to ensure correct measurement:
• Same electrical potential for the medium and sensor
• Remote version: same electrical potential for the sensor and transmitter
• Company-internal grounding concepts
• Pipe material and grounding
Connection example, standard scenario
Metal, grounded pipe
A0016315
14 Potential equalization via measuring tube
Endress+Hauser 27
Connection example in special situations
DN 300≤ DN 350≥
Unlined and ungrounded metal pipe
This connection method also applies in situations where:
• The customary potential equalization is not used
• Equalizing currents are present
Ground cable Copper wire, at least 6 mm2 (0.0093 in2)
15 Potential equalization via ground terminal and pipe flanges
Proline Promag L 400
A0029338
Note the following when installing:
• Connect both sensor flanges to the pipe flange via a ground cable and ground them.
• Connect the connection housing of the transmitter or sensor to ground potential by means of the
ground terminal provided for the purpose. To mount the ground cable:
– If DN ≤ 300 (12"): Mount the ground cable directly on the conductive flange coating of the
sensor with the flange screws.
– If DN ≥ 350 (14"): Mount the ground cable directly on the metal transport bracket.
For remote device versions, the ground terminal in the example always refers to the sensor and
not to the transmitter.
You can order the necessary ground cable from Endress+Hauser: → 86.
Plastic pipe or pipe with insulating liner
This connection method also applies in situations where:
• The customary potential equalization is not used
• Equalizing currents are present
Ground cable Copper wire, at least 6 mm2 (0.0093 in2)
16 Potential equalization via ground terminal and ground disks
Note the following when installing:
The ground disks must be connected to the ground terminal via the ground cable and be connected
to ground potential.
For remote device versions, the ground terminal in the example always refers to the sensor and
not to the transmitter.
The ground cable and ground disks can be ordered from Endress+Hauser → 86.
