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).

A0029932

The phase difference (A-B) increases with increasing mass flow. Electrodynamic sensors register the tube oscillations at the inlet and outlet. The measuring principle operates independently of temperature, pressure, viscosity, conductivity and flow profile.

Endress+Hauser 5

Page 6

Proline Promass A 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 →  109

• 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 →  108

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

Mounting location

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.

1) This orientation is recommended to ensure self-draining.

2) Applications with low process temperatures may decrease the ambient temperature. To maintain the minimum ambient temperature for the transmitter, this orientation is recommended.

3) Applications with high process temperatures may increase the ambient temperature. To maintain the maximum ambient temperature for the transmitter, this orientation is recommended.

If a sensor is installed horizontally with a curved measuring tube, match the position of the sensor to the fluid properties.

RUPTURE DISK

Inlet and outlet runs

Special mounting instructions

No special precautions need to be taken for fittings which create turbulence, such as valves, elbows or T-pieces, as long as no cavitation occurs →  61.

Drainability

When the device is installed in a vertical position, the measuring tube can be drained completely and protected against deposit buildup if the properties of the measured liquid allow this. Furthermore, as only one measuring tube is used the flow is not impeded and the risk of product being retained in the measuring device is reduced to a minimum. The larger internal diameter of the measuring tube

also reduces the risk of particles getting trapped in the measuring system. Due to the larger crosssection of the individual measuring tube, the tube is also generally less susceptible to clogging.

Sanitary compatibility

When installing in hygienic applications, please refer to the information in the "Certificates and approvals/hygienic compatibility" section →  101.

Rupture disk

Information that is relevant to the process: →  61.

WARNING

Danger from medium escaping!

Medium escaping under pressure can cause injury or material damage.

Take precautions to prevent danger to persons and damage if the rupture disk is actuated.

‣

Observe information on the rupture disk sticker.

‣

Make sure that the function and operation of the rupture disk is not impeded through the

‣

installation of the device. Do not remove or damage the rupture disk.

‣

The position of the rupture disk is indicated on a sticker applied over it. If the rupture disk is triggered, the sticker is destroyed. The disk can therefore be visually monitored.

If the sensor holder is used with a measuring device fitted with a rupture disk, it is important to ensure that the opening in the neck is not covered over and that the cover of the rupture disk is not damaged.

Zero point adjustment

All measuring devices are calibrated in accordance with state-of-the-art technology. Calibration takes place under reference conditions→  46. Therefore, a zero point adjustment in the field is generally not required.

Experience shows that zero point adjustment is advisable only in special cases:

• To achieve maximum measuring accuracy even with low flow rates.

• Under extreme process or operating conditions (e.g. very high process temperatures or very highviscosity fluids).

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

60 Endress+Hauser

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.

High-pressure devices are always fitted with a rupture disk: order code for "Measuring tube mat., wetted surface", option HB

Sensor housing nominal pressure rating and burst pressure

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").

To increase the level of safety, a device version with a rupture disk with a trigger pressure of 10 to 15 bar (145 to 217.5 psi)can be used (order code for "Sensor option", option CA "rupture disk").

High-pressure devices are always fitted with a rupture disk: order code for "Measuring tube mat., wetted surface", option HB

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 →  107

Pressure loss

System pressure

To calculate the pressure loss, use the Applicator sizing tool →  107

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

Thermal insulation

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.

NOTICE

Danger of overheating when heating

Ensure that the temperature at the lower end of the transmitter housing does not exceed

‣

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

‣

serves as a radiator and protects the electronics from overheating and excessive cooling. When using in potentially explosive atmospheres, observe the information in the device-specific

‣

Ex documentation. For detailed information on the temperature tables, see the separate document entitled "Safety Instructions" (XA) for the device.

The high oscillation frequency of the measuring tubes ensures that the correct operation of the measuring system is not influenced by plant vibrations.

Web server

Thanks to the integrated Web server, the device can be operated and configured via a Web browser and via a service interface (CDI-RJ45) or via a WLAN interface. The structure of the operating menu is the same as for the local display. In addition to the measured values, status information on the device is also displayed and allows the user to monitor the status of the device. Furthermore the device data can be managed and the network parameters can be configured.

A device that has a WLAN interface (can be ordered as an option) is required for the WLAN connection: order code for "Display; operation", option G "4-line, illuminated; touch control + WLAN". The device acts as an Access Point and enables communication by computer or a mobile handheld terminal.

Supported functions

Data exchange between the operating unit (such as a notebook for example) and the measuring device:

• Upload the configuration from the measuring device (XML format, configuration backup)

• Save the configuration to the measuring device (XML format, restore configuration)

• Export event list (.csv file)

• Export parameter settings (.csv file or PDF file, document the measuring point configuration)

• Export the Heartbeat verification log (PDF file, only available with the "Heartbeat Verification" application package)

HistoROM data management

The measuring device features HistoROM data management. HistoROM data management comprises both the storage and import/export of key device and process data, making operation and servicing far more reliable, secure and efficient.

When the device is delivered, the factory settings of the configuration data are stored as a backup in the device memory. This memory can be overwritten with an updated data record, for example after commissioning.

Storage location Fixed on the user interface board in the connection

compartment

Data backup

Automatic

• The most important device data (sensor and transmitter) are automatically saved in the DAT modules

• If the transmitter or measuring device is replaced: once the T-DAT containing the previous device data has been exchanged, the new measuring device is ready for operation again immediately without any errors

• If the sensor is replaced: once the sensor has been replaced, new sensor data are transferred from the S-DAT in the measuring device and the measuring device is ready for operation again immediately without any errors

• If exchanging the electronics module (e.g. I/O electronics module): Once the electronics module has been replaced, the software of the module is compared against the current device firmware. The module software is upgraded or downgraded where necessary. The electronics module is available for use immediately afterwards and no compatibility problems occur.
