Measuring principle Following Faraday's law of magnetic induction, a voltage is induced in a conductor moving through a
magnetic field.

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
Our warranty is valid only 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 settings.
IT security measures, which provide additional protection for the device and associated data transfer,
must be implemented by the operators themselves in line with their security standards.
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, Web browser 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 user-
specific 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.
• Infrastructure mode
When the device is operated in infrastructure mode, the WLAN passphrase corresponds to the
WLAN passphrase configured on the operator side.
User-specific access code
Write access to the device parameters via the local display, Web browser or operating tool (e.g.
FieldCare, DeviceCare) can be protected by the modifiable, user-specific access code.
WLAN passphrase: Operation as WLAN access point
A connection between an operating unit (e.g. notebook or tablet) and the device via the WLAN
interface, which can be ordered as an optional extra, 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.
Infrastructure mode
A connection between the device and WLAN access point is protected by means of an SSID and
passphrase on the system side. Please contact the relevant system administrator for access.
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 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 on device parameters, see:
The "Description of Device Parameters" document →  113
Access via OPC-UA
The "OPC UA Server" application package is available in the device version with the HART
communication protocol →  110.

Proline Promag W 500
10 Endress+Hauser
The device can communicate with OPC UA clients using the "OPC UA Server" application package.
The OPC UA server integrated in the device can be accessed via the WLAN access point using the
WLAN interface - which can be ordered as an optional extra - or the service interface (CDI- RJ45) via
Ethernet network. Access rights and authorization as per separate configuration.
The following Security Modes are supported as per the OPC UA Specification (IEC 62541):
• None
• Basic128Rsa15 – signed
• Basic128Rsa15 – signed and encrypted
Access via service interface (CDI-RJ45)
The device can be connected to a network via the service interface (CDI-RJ45). Device-specific
functions guarantee the secure operation of the device in a network.
The use of relevant industrial standards and guidelines that have been defined by national and
international safety committees, such as IEC/ISA62443 or the IEEE, is recommended. This includes
organizational security measures such as the assignment of access authorization as well as technical
measures such as network segmentation.
The device can be integrated in a ring topology. The device is integrated via the terminal
connection for signal transmission (output 1) and the connection to the service interface (CDI-
RJ45) →  99.

External measured values
To increase the accuracy of certain measured variables or to calculate the corrected volume flow, the
automation system can continuously write different measured values to the measuring device:
• Medium temperature to increase the accuracy of the electrical conductivity (e.g. iTEMP)
• Reference density for calculating the corrected volume flow
Various pressure transmitters and temperature measuring devices can be ordered from Endress
+Hauser: see "Accessories" section →  112
It is recommended to read in external measured values to calculate the corrected volume flow.
HART protocol
The measured values are written from the automation system to the measuring device via the HART
protocol. The pressure transmitter must support the following protocol-specific functions:
• HART protocol
• Burst mode
Current input
The measured values are written from the automation system to the measuring device via the
current input →  13.
Digital communication
The measured values can be written from the automation system to the measuring via:
• FOUNDATION Fieldbus
• PROFIBUS DP
• PROFIBUS PA
• Modbus RS485

Output
Output and input variants Depending on the option selected for output/input 1, different options are available for the other
outputs and inputs. Only one option can be selected for each output/input 1 to 4. The table must be
read vertically (↓).
Example: If the option BA "4–20 mA HART" was selected for output/input 1, one of the options A, B,
D, E, F, H, I or J is available for output 2, and one of the options A, B, D, E, F, H, I or J is available for
output 3 and 4.
