vFlow 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.

Proline Promag W 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 → 128

	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 → 128

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

28	Endress+Hauser

Proline Promag W 400

Connection example in special situations

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)

DN ≤ 300

DN ≥ 350

A0029338

15 Potential equalization via ground terminal and pipe flanges

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: → 126.

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)

A0029339

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 → 126.
