Function and system design
Measuring principle The measuring principle is based on the controlled generation of Coriolis forces. These forces are
always present in a system when both translational and rotational movements are superimposed.
Fc = 2 · ∆m (ν · ω)
Fc = Coriolis force
∆m = moving mass
ω = rotational velocity
ν = radial velocity in rotating or oscillating system
The amplitude of the Coriolis force depends on the moving mass ∆m, its velocity ν in the system and
thus on the mass flow. Instead of a constant rotational velocity ω, the sensor uses oscillation.
In the sensor, an oscillation is produced in the measuring tube. The Coriolis forces produced at the
measuring tube cause a phase shift in the tube oscillations (see illustration):
• If there is zero flow (i.e. when the fluid stands still), the oscillation measured at points A and B has
the same phase (no phase difference) (1).
• Mass flow causes deceleration of the oscillation at the inlet of the tubes (2) and acceleration at the
outlet (3).
2
13
A0029932
The phase difference (A-B) increases with increasing mass flow. Electrodynamic sensors register the
tube oscillations at the inlet and outlet. System balance is created by exciting an eccentrically
arranged swinging mass to antiphase oscillation. The measuring principle operates independently of
temperature, pressure, viscosity, conductivity and flow profile.

Proline Promass P 300

Density measurement
The measuring tube is continuously excited at its resonance frequency. A change in the mass and
thus the density of the oscillating system (comprising measuring tube and fluid) results in a
corresponding, automatic adjustment in the oscillation frequency. Resonance frequency is thus a
function of medium density. The microprocessor utilizes this relationship to obtain a density signal.
Volume measurement
Together with the measured mass flow, this is used to calculate the volume flow.
Temperature measurement
The temperature of the measuring tube is determined in order to calculate the compensation factor
due to temperature effects. This signal corresponds to the process temperature and is also available
as an output signal.
Measuring system The device consists of a transmitter and a sensor.
The device is available as a compact version:
The transmitter and sensor form a mechanical unit.

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 →  110
Access via OPC-UA
The "OPC UA Server" application package is available in the device version with the HART
communication protocol →  106.

Proline Promass P 300
Endress+Hauser 9
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) →  95.
