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, two parallel measuring tubes containing flowing fluid oscillate in antiphase, acting like
a tuning fork. The Coriolis forces produced at the measuring tubes cause a phase shift in the tube
oscillations (see illustration):

• At zero flow (when the fluid is at a standstill) the two tubes oscillate in phase (1).

• Mass flow causes deceleration of the oscillation at the inlet of the tubes (2) and acceleration at the
outlet (3).

A0028850

The phase difference (A-B) increases with increasing mass flow. Electrodynamic sensors register the
tube oscillations at the inlet and outlet. System balance is ensured by the antiphase oscillation of the
two measuring tubes. The measuring principle operates independently of temperature, pressure,
viscosity, conductivity and flow profile.

Endress+Hauser 5

Proline Promass O 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 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.

• 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 →  98

External measured values

To increase the accuracy of certain measured variables or to calculate the corrected volume flow for
gases, the automation system can continuously write different measured values to the measuring
device:

• Operating pressure to increase accuracy (Endress+Hauser recommends the use of a pressure
measuring device for absolute pressure, e.g. Cerabar M or Cerabar S)

• Medium temperature to increase accuracy (e.g. iTEMP)

• Reference density for calculating the corrected volume flow for gases

Various pressure transmitters and temperature measuring devices can be ordered from Endress
+Hauser: see "Accessories" section →  97

It is recommended to read in external measured values to calculate the corrected volume flow.

Mounting location

No special measures such as supports etc. are necessary. External forces are absorbed by the
construction of the device.

A0028772

To prevent measuring errors arising from accumulation of gas bubbles in the measuring tube, avoid
the following mounting locations in the pipe:

• Highest point of a pipeline.

• Directly upstream of a free pipe outlet in a down pipe.

Installation in down pipes

However, the following installation suggestion allows for installation in an open vertical pipeline.
Pipe restrictions or the use of an orifice with a smaller cross-section than the nominal diameter
prevent the sensor running empty while measurement is in progress.

Sensor housing

The sensor housing is filled with dry nitrogen gas and protects the electronics and mechanics inside.

If a measuring tube fails (e.g. due to process characteristics like corrosive or abrasive fluids), the
fluid will initially be contained by the sensor housing.

In the event of a tube failure, the pressure level inside the sensor housing will rise according to the
operating process pressure. If the user judges that the sensor housing pressure rating/burst pressure
does not provide an adequate safety margin, the device can be fitted with a rupture disk. This
prevents excessively high pressure from forming inside the sensor housing. Therefore, the use of a
rupture disk is strongly recommended in applications involving high gas pressures, and particularly
in applications in which the process pressure is greater than 2/3 of the sensor housing burst
pressure.

If there is a need to drain the leaking medium into a discharge device, the sensor should be fitted
with a rupture disk. Connect the discharge to the additional threaded connection →  66.

If the sensor is to be purged with gas (gas detection), it should be equipped with purge connections.

Do not open the purge connections unless the containment can be filled immediately with a
dry, inert gas. Use only low pressure to purge. Maximum pressure: 5 bar (72.5 psi).

Sensor housing nominal pressure rating and burst pressure

The following sensor housing nominal pressure ratings/burst pressures are only valid for standard
devices and/or devices equipped with closed purge connections (not opened/as delivered).

If a device fitted with purge connections (order code for "Sensor option", option CH "Purge
connection") is connected to the purge system, the maximum nominal pressure is determined by the
purge system itself or by the device, depending on which component has the lower nominal pressure
classification.

If the device is fitted with a rupture disk (order code for "Sensor option", option CA "Rupture disk"), the
rupture disk trigger pressure is decisive for the maximum nominal pressure .

The sensor housing burst pressure refers to a typical internal pressure which is reached prior to
mechanical failure of the sensor housing and which was determined during type testing. The
corresponding type test declaration can be ordered with the device (order code for "Additional
approval", option LN "Sensor housing burst pressure, type test").

Select the nominal diameter by optimizing between the required flow range and permissible pressure
loss.

For an overview of the full scale values for the measuring range, see the "Measuring range"
section →  10

• The minimum recommended full scale value is approx. 1/20 of the maximum full scale value

• In most applications, 20 to 50 % of the maximum full scale value can be considered ideal

• A low full scale value must be selected for abrasive media (such as liquids with entrained solids):
flow velocity < 1 m/s (< 3 ft/s).

• For gas measurement the following rules apply:

• The flow velocity in the measuring tubes should not exceed half the sound velocity (0.5 Mach).

• The maximum mass flow depends on the density of the gas: formula →  10

To calculate the flow limit, use the Applicator sizing tool →  96

Pressure loss

System pressure

Thermal insulation

To calculate the pressure loss, use the Applicator sizing tool →  96

It is important that cavitation does not occur, or that gases entrained in the liquids do not outgas.
This is prevented by means of a sufficiently high system pressure.

For this reason, the following mounting locations are recommended:

• At the lowest point in a vertical pipe

• Downstream from pumps (no danger of vacuum)

A0028777

In the case of some fluids, it is important to keep the heat radiated from the sensor to the
transmitter to a low level. A wide range of materials can be used for the required insulation.

The following device versions are recommended for versions with thermal insulation:

80 °C (176 °F).
Ensure that sufficient convection takes place at the transmitter neck.

‣

Ensure that a sufficiently large area of the transmitter neck remains exposed. The uncovered part

The measuring device is optionally tested in accordance with OIML R117 and has an
EU type evaluation certificate which authorizes the use in EU type-examination certificates according
to Measuring Instruments Directive 2014/32/EU for service subject to legal metrological control
("custody transfer") for liquids other than water(Annex VII).

The permitted fluid temperature in these applications is –10 to +90 °C (+14 to +194 °F).

The measuring device is optionally tested in accordance with OIML R137 and has an EU type­examination certificate according to Measuring Instruments Directive 2014/32/EU for service as a
gas meter subject to legal metrological control ("custody transfer") (Annex IV). The permitted fluid
temperature in these applications is –25 to +55 °C (–13 to +131 °F).

The device is used with a legally controlled totalizer on the local display and optionally with legally
controlled outputs.

Measuring devices subject to legal metrological control totalize in both directions, i.e. all the outputs
consider flow components in the positive (forward) and negative (reverse) flow direction.

Generally a measuring device subject to legal metrological control is secured against tampering by
seals on the transmitter or sensor. These seals may normally only be opened by a representative of
the competent authority for legal metrology controls.

After putting the device into circulation or after sealing the device, operation is only possible to a
limited extent.

Detailed ordering information is available from your local Endress+Hauser sales center for national
approvals, which are based on the OIML certificates, for applications with liquids other than water or
