Safety instructions
1.1
Designated use
The measuring device described in these Operating Instructions is to be used only for measuring the
mass flow rate of gases. At the same time, the system also measures gas temperature and calculates
other variables such as corrected volume flow. The measuring device can be configured to measure
pure gases or gas mixtures.
Examples:
• Compressed air
• Oxygen
• Nitrogen
• Carbon Dioxide
• Argon, etc.
The use with saturated and wet/dirty gases should be treated with caution (contact your
Endress+Hauser representative). The use with unstable gases should be avoided.
Resulting from incorrect use or from use other than that designated, the operational safety of the
measuring devices can be jeopardized. The manufacturer accepts no liability for damages being
produced from this.
1.2
Installation, commissioning and operation
Note the following points:
• Installation, connection to the electricity supply, commissioning and maintenance of the device
must be carried out by trained, qualified specialists authorised to perform such work by the
facility's owner operator.
The specialist must have read and understood these Operating Instructions and must follow the
instructions they contain.
• The device must be operated by persons authorised and trained by the facility's owner-operator.
Strict compliance with the instructions in the Operating Instruction is mandatory.
• Endress+Hauser is willing to assist in clarifying the chemical resistance properties of parts wetted
by special fluids, including fluids used for cleaning. However small changes in temperature,
concentration or the degree of contamination in the process can result in changes of the chemical
resistance properties. Therefore, Endress+Hauser can not guarantee or accept liability for the
chemical resistance properties of the fluid wetted materials in a specific application. The user is
responsible for the choice of fluid wetted materials in regards to their in-process resistance to
corrosion.
• If carrying out welding work on the piping, the welding unit should not be grounded by means
of the measuring device.
• The installer must ensure that the measuring system is correctly wired in accordance with the
wiring diagrams. The transmitter must be earthed unless special protection measures have been
taken e.g. galvanically isolated power supply SELV or PELV! (SELV = Safe Extra Low Voltage;
PELV = Protective Extra Low Voltage)
• Invariably, local regulations governing the opening and repair of electrical devices apply.

1.3
Operational safety
Note the following points:
• Measuring systems for use in hazardous environments are accompanied by separate
“Ex documentation”, which is an integral part of these Operating Instructions. Strict compliance
with the installation instructions and ratings as stated in this supplementary documentation is
mandatory.
The symbol on the front of this supplementary Ex documentation indicates the approval and the
certification body ( 0 Europe, 2 USA, 1 Canada).
• The measuring device complies with the general safety requirements in accordance with
EN 61010-1, the EMC requirements of EN 61326/A1, and NAMUR recommendation NE 21
and NE 53.
• The separate document on the Pressure Equipment Directive must be observed for devices used
in Category II, III or IV installations in accordance with the Pressure Equipment Directive.
• The manufacturer reserves the right to modify technical data without prior notice. Your
Endress+Hauser distributor will supply you with current information and updates to these
Operating Instructions.
1.4
Return
The following procedures must be carried out before a flowmeter requiring repair or calibration,
for example, is returned to Endress+Hauser:
• Always enclose a duly completed “Declaration of contamination” form. Only then can
Endress+Hauser transport, examine and repair a returned device.
• Enclose special handling instructions if necessary, for example a safety data sheet as per
EN 91/155/EEC.
• Remove all residues. Pay special attention to the grooves for seals and crevices which could
contain residues. This is particularly important if the substance is hazardous to health, e.g.
flammable, toxic, caustic, carcinogenic, etc.
!
#
Note!
You will find a preprinted “Declaration of contamination” form at the back of this manual.
Warning!
• Do not return a measuring device if you are not absolutely certain that all traces of hazardous
substances have been removed, e.g. substances which have penetrated crevices or diffused
through plastic.
• Costs incurred for waste disposal and injury (burns, etc.) due to inadequate cleaning will be
charged to the owner-operator.
1.5

Incoming acceptance, transport and storage
3.1.1
Incoming acceptance
On receipt of the goods, check the following points:
• Check the packaging and the contents for damage.
• Check the shipment, make sure nothing is missing and that the scope of supply matches your
order.
3.1.2
Transport
The following instructions apply to unpacking and to transporting the device to its final location:
• Transport the devices in the containers in which they are delivered.
• The covers or caps fitted to the process connections prevent mechanical damage to the
transducers during transportation and storage. Consequently, do not remove these covers or caps
until immediately before installation.
• Do not lift measuring devices of nominal diameters DN 40 to 100 (1½" to 4") by the transmitter
housing or the connection housing in the case of the remote version (Fig. 4). Use webbing slings
slung round the two process connections. Do not use chains, as they could damage the housing.
#
Warning!
Risk of injury if the measuring device slips. The center of gravity of the assembled measuring device
might be higher than the points around which the slings are slung.
At all times, therefore, make sure that the device does not unexpectedly turn around its axis or slip.

Instructions for transporting sensors with DN 40 to 100 (1½" to 4")
Storage
Note the following points:
• Pack the measuring device in such a way as to protect it reliably against impact for storage (and
transportation). The original packaging provides optimum protection.
• The permissible storage temperature is –40 to +80 °C (–40 °F to 176 °F).
Preferably +20 °C (+68 °F).
• Do not remove the protective covers or caps on the process connections until you are ready to
install the device.
• The measuring device must be protected against direct sunlight during storage in order to avoid
unacceptably high surface temperatures.

3.2
Installation conditions
Note the following points:
• The thermal dispersion principle is very sensitive to low flow rates and disturbed flow conditions.
• Observe the recommended inlet and outlet requirements.
• Good engineering practice is necessary for the associated pipe work and installation.
• Ensure correct alignment and orientation of the sensor.
• Avoid condensation forming around the transducers.
• Consider the nature of the gas or gas mixture (dryness, cleanliness, stability, fraction, etc.)
• The maximum permitted ambient temperatures (→ Page 89) and the medium temperature
range (→ Page 89) must be observed.
• If possible, locate the sensor to avoid extreme changes in ambient temperature and process
condititons.
• For mechanical reasons, and in order to protect the pipe, it is advisable to support heavy sensors.
3.2.1
Dimensions
All the dimensions and lengths of the sensor and transmitter are provided in the separate
documentation “Technical Information”.
3.2.2
Pipework requirements
Good construction practice should be followed at all times:
• Correct welding techniques
• Correctly sized gaskets
• Correctly aligned flanges and gaskets
• The use of seamless pipe immediately upstream of the flowmeter.
• The use of pipework with a matching internal diameter to that of the flowmeter to ensure that no
step disturbance greater than 1 mm (0.04 inch) can occur at the meter inlet or outlet
(3 mm (0.12 inch) for diameters > DN 200 (8")).
• As a general comment, anything that disturbs the smoothness of the internal pipe wall within the
dimensions stated below should be eliminated; the goal should be a smooth uninterrupted internal surface.
For further information please refer to ISO 14511.

Installation
Orientation
The device can generally be installed in any position in the piping. In the case of wet/dirty gases,
upward flow is prefered in vertical pipes to minimise condensation/contamination. Where free
condensation can occur (e.g. Biogas) the sensor should be orientated to prevent water collecting on
or around the transducer.
Make sure that the direction arrow on the sensor matches the direction of flow (direction of fluid
flow through the pipe).

3.2.4
Inlet and outlet runs
The sensitivity of the thermal dispersion principle to low flow rates means the flowmeter can also
be sensitive to internal disturbances in the flowing gas stream (e.g. swirl), especially in the larger
pipe diameters ≥ DN 150 (≥ 6").
As a general rule, the installed thermal flow sensor should always be installed as far away as possible
from any flow disturbances (see ISO14511 for further information).
Process components or pipework configuration
When disturbances (e. g. pipe elbows, reducers, valves, T-pieces etc.) are located upstream of the
thermal meter, precautions must be taken to minimise any effects on the measuring performance.
The figure on the following page illustrates the minimum recommended inlet and outlet runs,
expressed in multibles of the pipe diameter. Longer lengths should always be used if they are
available.
Regardless of any other consideration, the minimum recommendations for inlet and outlet runs on
either side of the sensor are:
Inlet runs:
Minimum 15 x DN for the flanged version (65F)
Minimum 20 x DN for the insertion version (65I)
Outlet runs:
Minimum 2 x DN for the flanged version (65F)
Minimum 5 x DN for the insertion version (65I)
!
14
Note!
• These are minimum values, increasing these dimensions will often improve the flowmeter
perfomance.
• Where two or more disturbances are located upstream of the meter, the longest recommended
upstream pipe run is to be observed as an absolute minimum.
• It is always recomended to install control valves downstream of the flowmeter.
• For very light gases such as Helium and Hydrogen all upstream distances should be doubled.

Flow conditioner (35 hole) for use with insertion sensors
The well known "Mitsubishi" design is recommended for this application DN 80 mm (3") to DN
300 mm (12"). For the majority of gas types, the flow conditioner must be installed at a distance of
10 x DN upstream of the sensor. A further 5 pipe diameters inlet run is required upstream of the
actual conditioner itself.
Flow conditoner (19 hole) for use with flanged sensors
This is a special Endress+Hauser version designed specially for use with the t-mass F sensor (Sizes
DN 25 to 100 /1" to 4"). The flow conditioner should be fitted immediately upstream of the flanged
sensor. A further 5 pipe diameters inlet run is required upstream of the actual conditioner itself.
For optimum performance, it is advised that the t-mass F sensor and flow conditioner are ordered
at the same time such that they are calibrated together. To retrospectively fit a flow conditioner will
have a small effect on the measurement performance.
!
Note!
The use of other types of flow conditioners, other than the Endress+Hauser flow conditioner, with
the t-mass F sensor will have an impact on the measurement performance due to the effects of flow
profile and pressure drop.
The flow conditioner is fitted between two piping flanges and centered with mounting bolts.

3.2.7
Flow direction alignment for the flanged version
The arrows on the sides of the sensor housing assembly are pointing in the same direction as the
flow.
3.2.8
Flow direction alignment for the insertion version
It is very important that the sensor is aligned correctly with the direction of flow. There are two
guidelines for correct alignment:
• The arrows on the sides of the sensor housing assembly are pointing in the same direction as the
flow.
• The graduated scale on the insertion tube section should be aligned directly upstream of the flow
direction.
To ensure optimum exposure of the measuring transducers to the flowing gas stream, the sensor
must not be rotated more than 7 degrees from this alignment.

Vertical alignment
It is important that the sensor mounting boss is welded to the pipe or duct such that the sensor is
mounted at 90 degrees to the flow direction. Any deviation from this angle in any plane may cause
flow disturbances around the measuring point that could cause errors.
!
Note!
The thermal sensor cannot differntiate between forward and reverse flow. These guidelines are only
to ensure correct installation and aligment.
3.2.9
Insertion depth for the insertion version
Sensor installation - Adjustable insertion sensor
When installing the sensor, the following three dimensions need to be taken into account to allow
the correct insertion length to be specified:
• A = Internal diameter of the circular pipe. For a rectangular duct; the duct height if the sensor is
to be mounted vertically or duct width if it is to be mounted horizontally
• B = Pipe wall or duct wall thickness
• C = Depth of mounting boss on the pipe or duct, including the sensor compression fitting and
cold tap (if used).

Dimensions required to calculate the sensor insertion depth
Insertion sensors fitted with an adjustable insertion probe depth
(i. e. screwed process connection)
The tube section is supplied with a graduated scale along its length (in millimetres or inches). It is
important that the sensor be installed so that the top of the compression fitting is aligned with the
value on the scale that is equal to the following calculated value:
For pipe diameter:
• = DN 80 (3"): (0.3 x A) + B + C + 2 mm (0.079 inch)
• ≥ DN 100 (4"): (0.2 x A) + B + C + 3 mm (0.12 inch)
For duct width (horizontal installation) or duct height (vertical installation):
• < DN 100 (4"): (0.3 x A) + B + C + 2 mm (0.079 inch)
• ≥ DN 100 (4"): (0.2 x A) + B + C + 3 mm (0.12 inch)
When the sensor is at the correct insertion depth the sensor must next be aligned for the correct
flow direction detection. After alignment, the compression fitting must be tightened to secure and
seal the insertion tube. Tighten the two securing screws.

Installing
The mounting location is determined by the installation requirements for an insertion type sensor.
Pay particular attention to mounting orientation and inlet and outlet length. See this chapter for
details.
#
Warning!
Stop the process gas flow and de-pressurize the process line. Purge the line with an inert gas to
remove any hazardous or toxic gases. Allow the installation to cool to a safe temperature. Check
and verify that this is so before handling any metal parts. Ensure that the process cannot be restarted during the installation procedure.
1.
A cut-out of 31.0 mm ±0.5 mm (1.22" ±0.019") is required for the process fitting. Mark the
pipe accordingly and cut the hole with a suitable tool.
2.
Finish the edges of the hole to ensure that all burrs are removed and that the required tolerance
is met. Remove any particles that may have fallen into the pipe.
3.
Insert the process fitting into the pipe (a) and support it such that it is vertically aligned. Weld
the fitting to the pipe.
4.
Check the integrity of the installation by running a static pressure test. Insert a blanking plug
into the screwed fitting end of the tube (b), open the ball valve (c) and apply pressure. Check
for leaks and, if necessary, correct the installation fault and repeat static pressure test.

System pressure
Reciprocating pumps and some compressor systems can create strong changes in process pressure
that can induce spurious internal flow patterns and therefore cause additional measurement error.
These pressure pulses must be reduced by the appropriate measures:
• Use of expansion tanks
• Use of inlet expanders
• Relocate the thermal measuring device

Installation
External pressure compensation
An external pressure compensating via MODBUS communication is useful in cases where:
• Large variations of pressure are likely to occur e.g. 2 to 8 bar (30 to 120 psi) with air applications
• The thermal properties of the gas are likely to vary e.g. Ammonia gas
Transmission of pressure value via MODBUS:
The value of the process pressure can be transmitted via MODBUS communication to the measuring
device. See Description of Device Functions manual, PROCESS PRESSURE function, for more
information.
!
Note!
• A pressure transmitter with an absolute pressure range must be used.
• In-situ calibration is not possible if an external pressure compensation is being used.
In-situ calibration writes a new calibration curve at the actual process condition, pressure
compensation is disabled.
3.2.13
Temperature range
The following requirements and limits must be observed:
• It is recommended to install the sensor out of any direct sunlight or away from any extremes of
temperature.
• The maximum approved ambient and process temperatures (see Page 89 ff.)
• Instructions on heating and thermal insulation (see Page 23 ff.)
3.2.14
Heating
Some gases require suitable measures to avoid loss of heat at the sensor and therefore condensation.
Heating can be electric, e. g. with heated elements, or by means of hot water or steam pipes.
"
Caution!
• Risk of electronics overheating! Consequently, make sure that the adapter between sensor and
transmitter and the connection housing of the remote version always remain free of insulating
material.
• When using electrical heat tracing whose heat is regulated using phase control or by pulse packs,
it cannot be ruled out that the measured values are influenced by magnetic fields which may
occur (i. e. at values greater than those permitted by the EC standard minus 30 A/m). In such
cases, the sensor must be magnetically screened.
23
Installation
Proline t-mass 65 MODBUS RS485
3.2.15
Thermal insulation
When the gas is very humid or saturated with water (eg. Bio Gas) the pipeline and flowmeter body
should be insulated to prevent water droplets condensing on the pipe wall and/or flow transducer.
In extreme cases of moisture and temperature variation, it may be advisable to provide trace heating
of the pipework and/or sensor body.

4.1.2
Shielding and grounding
When planning the shielding and grounding for a fieldbus system, there are three important points
to consider:
• Electromagnetic compatibility (EMC)
• Explosion protection
• Safety of the personnel
To ensure the optimum electromagnetic compatibility of systems, it is important that the system
components and above all the cables, which connect the components, are shielded and that no
portion of the system is unshielded. Ideally, the cable shields are connected to the normally metal
housings of the connected field devices. Since these are generally connected to the protective earth,
the shield of the bus cable is grounded many times. Keep the stripped and twisted lengths of cable
shield to the terminals as short as possible.
This approach, which provides the best electromagnetic compatibility and personnel safety, can be
used without restriction in systems with good potential matching.
In the case of systems without potential matching, a power supply frequency (50 Hz) equalizing
current can flow between two grounding points which, in unfavorable cases (e.g. when it exceeds
the permissible shield current) may destroy the cable.
To suppress the low frequency equalizing currents on systems without potential matching, it is
therefore recommended to connect the cable shield directly to the building ground (or protective
earth) at one end only and to use capacitive coupling to connect all other grounding points.
"
30
Caution!
The legal EMC requirements are fulfilled only when the cable shield is grounded on both ends!

Degree of protection
The devices fulfill all the requirements for IP 67.
Compliance with the following points is mandatory following installation in the field or servicing,
in order to ensure that IP 67 protection is maintained:
• The housing seals must be clean and undamaged when inserted into their grooves.
The seals must be dried, cleaned or replaced if necessary.
• All threaded fasteners and screw covers must be firmly tightened.
• The cables used for connection must be of the specified outside diameter, see Page 88 (Cable
entry)
• Firmly tighten the cable entries.
• The cables must loop down before they enter the cable entries (“water trap”).
This arrangement prevents moisture penetrating the entry. Always install the measuring device
in such a way that the cable entries do not point up.
• Remove all unused cable entries and insert plugs instead.
• Do not remove the grommet from the cable entry.

Operation
General notes
The Quick Setup menu contains the default settings that are adequate for commissioning.
Complex measuring operations on the other hand necessitate additional functions that you can
configure as necessary and customise to suit your process parameters. The function matrix,
therefore, comprises a multiplicity of additional functions which, for the sake of clarity, are arranged
in a number of function groups.
Comply with the following instructions when configuring functions:
• You select functions as described already. → Page 37
• You can switch off certain functions (OFF). If you do so, related functions in other function groups
will no longer be displayed.
• Certain functions prompt you to confirm your data entries. Press P to select “SURE ( YES )” and
press F to confirm. This saves your setting or starts a function, as applicable.
• Return to the HOME position is automatic if no key is pressed for 5 minutes.
• Programming mode is disabled automatically if you do not press a key within 60 seconds
following automatic return to the HOME position.
"
!
Caution!
All functions are described in detail, as is the function matrix itself, in the “Description of Device
Functions” manual, which is a separate part of these Operating Instructions.
Note!
• The transmitter continues to measure while data entry is in progress, i.e. the current measured
values are output via the signal outputs in the normal way.
• If the power supply fails all preset and parameterised values remain safely stored in the EEPROM.
• However, some functions may be affected (i. e. data/values not saved) if the power supply is
interupted during editing or operation of those functions. More details are contained in the
“Description of Device Functions” manual, BA116D/06/en/… .
5.3.2
Enabling the programming mode
The function matrix can be disabled. Disabling the function matrix rules out the possibility of
inadvertent changes to device functions, numerical values or factory settings. A numerical code
(factory setting = 65) has to be entered before settings can be changed.
If you use a code number of your choice, you exclude the possibility of unauthorised persons
accessing data ( → see the “Description of Device Functions” manual).
Comply with the following instructions when entering codes:
• If programming is disabled and the P operating elements are pressed in any function, a prompt
for the code automatically appears on the display.
• If “0” is entered as the customer's code, programming is always enabled.
• Your Endress+Hauser representative can be of assistance if you mislay your personal code.
"
Caution!
Changing certain parameters such as all sensor characteristics, for example, influences numerous
functions of the entire measuring system, particularly measuring accuracy.
There is no need to change these parameters under normal circumstances and consequently, they
are protected by a special code known only to the Endress+Hauser representative. Please contact
Endress+Hauser if you have any questions.
5.3.3
Disabling the programming mode
Programming mode is disabled if you do not press an operating element within 60 seconds following
automatic return to the HOME position.
You can also disable programming in the “ACCESS CODE” function by entering any number (other
than the customer's code).

MODBUS RS485 communication
5.5.1
MODBUS RS485 technology
The MODBUS is an open, standardized fieldbus system which is deployed in the areas of
manufacturing automation, process automation and building automation.
System architecture
The MODBUS RS485 is used to specify the functional characteristics of a serial fieldbus system with
which distributed, digital automation systems are networked together.
The MODBUS RS485 distinguishes between master and slave devices.
• Master devices
Master devices determine the data traffic on the fieldbus system. They can send data without an
external request.
• Slave devices
Slave devices, like this measuring device, are peripheral devices. They do not have their own
access rights to the data traffic of the fieldbus system and only send their data due to an external
request from a master.

Master/slave communication
A distinction is made between two methods of communication with regard to master/slave
communication via MODBUS RS485:
• Polling (request-response-transaction)
The master sends a request telegram to one slave and waits for the slave's response telegram.
Here, the slave is contacted directly due to its unique bus address (1 to 247).

MODBUS telegram
General
The master-slave process is used for data exchange. Only the master can initiate data transmission.
Following the prompt, the slave sends the master the necessary data as a response telegram or
executes the command requested by the master.
Telegram structure
The data is transferred between the master and slave by means of a telegram.
A request telegram from the master contains the following telegram fields:
Telegram structure:
Slave address
Function code
Data
Check sum
• Slave address
The slave address can be in an address range from 1 to 247.
The master talks to all the slaves simultaneously by means of the slave address 0 (broadcast
message).
• Function code
The function code determines which read, write and test operations should be executed by means
of the MODBUS protocol.
Function codes supported by the measuring device → Page 44
• Data
Depending on the function code, the following values are transmitted in this data field:
– Register start address (from which the data is transmitted)
– Number of registers
– Write/read data
– Data length
– etc.
• Check sum (CRC or LRC check)
The telegram check sum forms the end of the telegram.
The master can send another telegram to the slave as soon as it has received an answer to the
previous telegram or once the time-out period set at the master has expired. This time-out period
can be specified or modified by the user and depends on the slave response time.
If an error occurs during data transfer or if the slave cannot execute the command from the master,
the slave returns an error telegram (exception response) to the master.
The slave response telegram consists of telegram fields which contain the requested data or which
confirm that the action requested by the master has been executed. It also contains a check sum.

Operation
5.5.4
Maximum number of writes
If a nonvolatile device parameter is modified via the MODBUS function codes 06, 16 or 23, this
change is saved in the EEPROM of the measuring device.
The number of writes to the EEPROM is technically restricted to a maximum of 1 million. Attention
must be paid to this limit since, if exceeded, it results in data loss and measuring device failure. For
this reason, avoid constantly writing nonvolatile device parameters via the MODBUS!
5.5.5
MODBUS register addresses
Each device parameter has its own register address. The MODBUS master uses this register address
to talk to the individual device parameters and access the device data. The register addresses of the
individual device parameters can be found in the “Description of Device Functions” manual under
the parameter description in question.

– Data type: float (length = 4 bytes), integer (length = 2 bytes), string (length = depends on function)
– Possible ways of accessing the function:
read = read access via function code 03, 04 or 23
write = write access via 06, 16 or 23
MODBUS register address model
The MODBUS RS485 register addresses of the measuring device are implemented in accordance
with “MODBUS Applications Protocol Specification V1.1”.
!
Note!
In addition to the specification mentioned above, systems are also deployed which work with a
register address model in accordance with the “Modicon MODBUS Protocol Reference Guide (PI-MBUS-300 Rev. J)” specification. With this specification, the register address is extended,
depending on the function code used. A “3” is put in front of the register address in the “read”
access mode and a “4” in the “write” access mode.

Response times
The time it takes a measuring device to respond to a request telegram from the MODBUS master is
typically 25 to 50 ms. If faster response times are needed for time-critical applications, the “autoscan buffer” is to be used.
!
Note!
It may take longer for a command to be executed in the device. The data is not updated until the
command has been executed. Especially write commands are affected by this!

Operation
Byte transmission sequence
Byte addressing, i.e. the transmission sequence of the bytes, is not specified in the MODBUS
specification. For this reason, it is important to coordinate the addressing method between the
master and slave during commissioning. This can be configured in the measuring device by means
of the “BYTE ORDER” parameter (see “Description of Device Functions” manual).
Depending on the selection in the “BYTE ORDER” parameter, the bytes are transmitted as follows:

MODBUS error messages
If the MODBUS slave detects an error in the request telegram from the master, it sends a reply to
the master in the form of an error message consisting of the slave address, function code, exception
code and check sum. To indicate that this is an error message, the lead bit of the returned function
code is used. The reason for the error is transmitted to the master by means of the exception code.
The following exception codes are supported by the measuring device:

SLAVE DEVICE FAILURE
The slave did not respond to the request telegram from the master or an error occurred when
processing the request telegram.
MODBUS auto-scan buffer
Function description
The MODBUS master uses the request telegram to access the device parameters (data) of the
measuring device. Depending on the function code, the master gains read or write access to a single
device parameter or a group of consecutive device parameters. If the desired device parameters
(registers) are not available as a group, the master has to send a request telegram to the slave for
each parameter.
The measuring device has a special storage area, known as the auto-scan buffer, for grouping
nonconsecutive device parameters. This can be used to flexibly group up to 16 device parameters
(registers). The master can talk to this complete data block by means of just one request telegram.
Structure of the auto-scan buffer
The auto-scan buffer consists of two data records, the configuration area and the data area. In the
configuration area, a list known as the scan list specifies which device parameters should be
grouped. For this purpose, the corresponding register address, e.g. the register address 2007 for
mass flow, is entered in the scan list. Up to 16 device parameters can be grouped.
The measuring device cyclically reads out the register addresses entered in the scan list and writes
the associated device data to the data area (buffer). The request cycle runs automatically. The cycle
starts again when the last entry in the scan list has been queried.
By means of MODBUS, the grouped device parameters in the data area can be read or written by
the master with just one request telegram (register address 5051 to 5081).

Proline t-mass 65 MODBUS RS485
Operation
Configuration of the scan list
During configuration, the MODBUS register addresses of the device parameters to be grouped must
be entered in the scan list. The scan list can contain up to 16 entries. Float and Integer-type device
parameters with read and write access are supported.
The scan list can be configured by means of:
1.
The local display or a operating program (e.g. ToF Tool - Fieldtool Package or FieldCare).
The scan list is configured here by means of the function matrix:
COMMUNICATION → SCAN LIST REG. 1 to SCAN LIST REG. 16
2.
The MODBUS master.
Here, the scan list is configured via the register addresses 5001 to 5016.

Access to data via MODBUS
The MODBUS master uses the register addresses 5051 to 5081 to access the data area of the
auto-scan buffer. This data area contains the values of the device parameters defined in the scan list.
For example, if the register 2007 was entered for mass flow in the scan list by means of the
SCAN LIST REG. 1 function, the master can read out the current measured value of the volume
flow in register 5051.

Operation
Example
The following device parameters should be grouped via the auto-scan buffer and read out by the
master with just one request telegram:
• Mass flow → Register address 2007
• Totalizer 1 → Register address 2610
• Actual system condition → Register address 6859
1. Configuration of the scan list
• With the local operation or a operating program (via the function matrix):
COMMUNICATION function group → SCAN LIST REG. function:
→ Entry of the address 2007 under SCAN LIST REG. 1
→ Entry of the address 2610 under SCAN LIST REG. 2
→ Entry of the address 6859 under SCAN LIST REG. 3
• Via the MODBUS master (the register addresses of the device parameters are written to the
registers 5001 to 5003 via MODBUS):
1. Write address 2007 (mass flow) to register 5001
2. Write address 2610 (totalizer 1) to register 5002
3. Write address 6859 (actual system condition) to register 5003

6.4
Adjustment
6.4.1
Zero point adjustment
At zero flow conditions, the output of most thermal mass flow devices has a strong dependency on
the process pressure.
The effect on the true zero point of the device, by the static line pressure, is dependant on the gas
type and the application demands and in many cases the use of the low flow cut-off function is
adequate to zero the device output. Consequently, the zero point adjustment is generally not
necessary for t-mass!
However, with some gases and /or a combination of high static line pressures, the zero point may
need to be adjusted under process conditions to restore the very low measurement capability of the
device.
Therefore, the zero point adjustment is advisable in the following special cases:
• To achieve highest measuring accuracy also with very small flow rates.
• Under process or operating conditions where the gas properties differ strongly from air properties
e.g. Hydrogen and Helium.
Preconditions for a zero point adjustment
Note the following before you perform a zero point adjustment:
• A zero point adjustment can be performed only with gases that contain no solid contents.
• The adjustment is performed with the process gas at zero flow and at operating pressure. This can
be achieved, for example, with shut-off valves upstream and/or downstream of the sensor.
– Normal operation → valves 1 and 2 open
– Zero point adjustment → valve 1 open / valve 2 closed
– Zero point adjustment → valve 1 closed / valve 2 open

Commissioning
Proline t-mass 65 MODBUS RS485
Performing a zero point adjustment
1.
Operate the system until operating conditions have settled.
2.
Stop the flow (v = 0 m/s).
3.
Check the shut-off valves for leaks.
4.
Check that operating pressure is correct.
5.
Using the local display, select the zero point adjustment function in the function matrix:
PROCESS PARAMETER → ZERO POINT ADJUST
6.
When you press O or S you are automatically prompted to enter the access code if the
function matrix is still disabled. Enter the code (factory setting = 65).
7.
Use O or S to select START and press F to confirm. Select YES at the prompt SURE? and press
F again to confirm. Zero point adjustment now starts.
– The message # 561 “ZERO-ADJ. RUN” appears on the display while adjustment is in
progress.
! Note!
– If the flow in the pipe is unstable, the following error message may appear on the display
# 451 “ZERO-ADJ. N. OK”. The Zero point adjustment is not OK. The preconditions need
to be stabilized before attempting a new adjustment.
8.
Back to the HOME position:
– Press and hold down Esc key (X) for longer than three seconds or
– Repeatedly press and release the Esc key (X).
Resetting a zero point adjustment
The currently stored zero point can be reset to the original factory value by using the RESET option
within ZERO POINT ADJUST function.
Use O or S to select RESET and press F to confirm. Select YES at the prompt SURE? and press F
again to confirm. The zero point adjustment is now reset.
6.5
Data storage device (HistoROM)
At Endress+Hauser, the term HistoROM refers to various types of data storage modules on which
process and measuring device data are stored. By plugging and unplugging such modules, device
configurations can be duplicated onto other measuring devices to cite just one example.
6.5.1
HistoROM/S-DAT (sensor-DAT)
The S-DAT is an exchangeable data storage device in which all sensor relevant parameters are
stored, i.e., pipe type, diameter, serial number, flow conditoner, zero point.
6.5.2
HistoROM/T-DAT (transmitter-DAT)
The T-DAT is an exchangeable data storage device in which all transmitter parameters and settings
are stored.
Storing of specific parameter settings from the EEPROM to the T-DAT and vice versa has to be
carried out by the user (= manual save function). Detailed instructions regarding this can be found
in the handbook “Description of Device Functions” (function “T-DAT SAVE/LOAD”).

Maintenance
Maintenance
Generally, the flowmeter requires no special maintenance work, particularly if the gas is clean and
dry.
7.1
External cleaning
When cleaning the exterior of measuring devices, always use cleaning agents that do not attack the
surface of the housing and the seals.
7.2
Pipe cleaning
The sensor is capable of withstanding clean in place (CIP) processes using heated liquids or steam
(SIP), within the maximum specified temperature limits. However the sensor measurement will be
adversely affected during the cleaning cycle and a settling down period will be required after the
cycle to allow the process and sensor temperatures to re-stabilise.
!
"
Note!
The POSITIVE ZERO RETURN function maybe activated to set the measured variables (mass flow,
corrected volume flow) to zero flow during such cycles. See "Description of Device Functions”
manual for more information.
Caution!
Do not use a pipe cleaning pig.
7.3
Transducer cleaning
For gases that do carry impurities, it is recommended that the sensor be routinely inspected and
cleaned to minimise any potential metering errors due to contamination or build-ups. The frequency
of inspection and cleaning will depend upon the application and expected measurement
performance. A suitable cleaning agent that does not attack the materials or seals maybe used.
• t-mass F sensor: Removal of the transducer may be carried out subject to the requirements of
Pressure Equipment Directive, CRN approvals, and relevant hazardous area standards. In case of
EX approved versions, the o-ring seals must be replaced at the same time. Please consult your
Endress+Hauser service representative.
• t-mass I sensor: Cleaning of this sensor is straight forward - no special limitations.
!
Note!
Use care not to bend the sensing elements of the transducer.
7.4
Replacing seals
t-mass F sensor:
Under normal circumstances, fluid wetted seals of the sensor do not require replacement.
Replacement is necessary only in special circumstances, for example if aggressive or corrosive fluids
are incompatible with the seal material.
t-mass I sensor:
The transducer is welded to the insertion tube and has no exchangeable seals. The compression
fitting contains wetted seals (non exchangeable) and a bonded seal is used on G 1 A threads.
The compression fitting and bonded seal are available as spare parts.
7.5
In-situ calibration
The t-mass flowmeters are designed to support in-situ calibration using a reference meter signal,
thus saving time and cost by reducing the need for factory re-calibration.
Please discuss your specific requirements with your Endress+Hauser service representative.

Note!
You may have to change or correct certain settings of the function matrix in order to rectify faults. The functions outlined below, such as DISPLAY DAMPING, for
example, are described in detail in the “Description of Device Functions” manual.
Displayed measured value fluctuates
even though flow is steady.
Device displays flow with no actual
flow present.
Device displays flow with no actual
flow present - but with high static

Technical data at a glance
10.1.1
Applications
The measuring device described in these Operating Instructions is to be used only for measuring the
mass flow rate of gases. At the same time, the system also measures corrected volume flow,
temperature and calculated density.
Examples:
• Compressed air
• Oxygen
• Nitrogen
• Carbon dioxide
• Bio gas, etc.
Resulting from incorrect use or from use other than that designated the operational safety of the
measuring devices can be jeopardized. The manufacturer accepts no liability for damages being
produced from this.
10.1.2
Function and system design
Measuring principle
Mass flow measurement by the thermal dispersion principle.
Measuring system
The t-mass 65 flow measuring system consists of the following components:
• t-mass 65 transmitter
• t-mass F, t-mass I sensor
Two versions are available:
• Compact version: transmitter and sensor form a single mechanical unit.
• Remote version: transmitter and sensor are installed separately.
10.1.3
Input
Measured variable
• Mass flow
• Gas temperature
Measuring range
The measuring range is dependent on the gas selection, line size and use of flow conditioner. Each
meter is individually calibrated on air and mathematically converted to suit the customer specific
gas, where required.
The tables below define the ranges available for air without flow conditoner. Please refer to your
Endress+Hauser representative or to Applicator (the Endress+Hauser sizing and selection software)
