Proline t-mass 65 PROFIBUS DP/PA Safety instructions
1 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 (e. g. kg, Nm
temperature. The measuring device can be configured to measure a standard range of pure gases or
gas mixtures.
Examples:
•Air
• Oxygen
• Nitrogen
• Carbon Dioxide
•Argon, etc.
The use with corrosive, saturated or unclean gases should be treated with caution (contact your
Endress+Hauser sales representative). The use with unstable gases or gases not deemed to be
suitable by Endress+Hauser must be avoided. The measuring device is not designed to be used with
liquids or fluids in the liquid phase.
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.

scf). At the same time, the system also measures gas
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.

Safety instructions Proline t-mass 65 PROFIBUS DP/PA
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 (e.g. 0 Europe, 2 USA, 1 Canada).
• When hot fluid passes through the measuring tube, the surface temperature of the housing
increases. In the case of the sensor, in particular, users should expect temperatures that can be
close to the fluid temperature. If the temperature of the fluid is high, implement sufficient
measures to prevent burning or scalding.
• The measuring device complies with the general safety requirements in accordance with
EN 61010-1, the EMC requirements of IEC/EN 61326, and NAMUR recommendation NE 21,
NE 43 and NE 53.
• The separate document on the Pressure Equipment Directive must be observed for devices used
in Category II or III 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
• 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.
• Please note the measures on ä 106
1.5 Notes on safety conventions and icons
The devices are designed to meet state-of-the-art safety requirements, have been tested, and left the

• 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 (> 1½") by the transmitter housing
or the connection housing in the case of the remote version ( å 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.
a0004294
Fig. 4: Instructions for transporting sensors with > DN 40 (> 1½")
3.1.3 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.
• Devices delivered with special sealing or bagging for oxygen service must remain sealed or bagged
until ready for installation.

3.2 Installation conditions
Note the following points:
• The thermal dispersion principle is very sensitive to 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.
• Take measures to reduce or avoid condensation (e.g. install a condensation trap, thermal
insulation, etc.).
• The maximum permitted ambient temperatures and the medium temperature range ( ä 111)
must be observed.
• Install the transmitter in a shaded location or use a protective sun shield.
• For mechanical reasons, and in order to protect the pipe, it is advisable to support heavy sensors.
3.2.1 Dimensions
The dimensions and installation lengths of the sensor and transmitter can be found in the "Technical
Information" for the device in question. This document can be downloaded as a PDF file from
www.endress.com. A list of the "Technical Information" documents available is provided in the
"Documentation" section on ä 116.
3.2.2 System pressure and pulsating flow
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 flowmeter further downstream
In compressed air systems, it is recommended to mount the flowmeter after the filter, dryer and
buffer devices to avoid pulsations and oil/dirt contamination. Do not mount the flowmeter directly
after the compressor outlet.

3.2.3 Pipework requirements
Good engineering practice should be followed at all times:
• Correct preparation, welding and finishing techniques
• Correctly sized gaskets
• Correctly aligned flanges and gaskets
• Connecting pipe work should match the internal diameter of the flowmeter.
Maximum pipe diameter mismatch should not exceed:
– 1 mm (0.04 inch) for diameters < DN 200 (8")
– 3 mm (0.12 inch) for diameters DN 200 (8")
For further information please refer to ISO 14511.

3.2.5 Inlet and outlet runs
The thermal dispersion principle is sensitive to disturbed flow conditions.
As a general rule, the thermal flowmeter should always be installed as far away as possible from any
flow disturbances. For further information please refer to ISO 14511.
!
Note!
• Where two or more flow disturbances are located upstream of the meter, the longest indicated
inlet length should prevail. For example if a control valve and a bend are mounted upstream of
the flowmeter, the recommended inlet length should be according to the control valve (50 × DN).
• For very light gases such as Helium and Hydrogen all upstream distances should be doubled.
The minimum recommendations for inlet and outlet runs (without flow conditioner) are:

Flow conditoner for use with flanged sensors ä 87
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 mounting hole patterns and sizing are of a multi-variant design which
means that one plate will fit different flange pressure classes e.g. Cl. 150 and Cl. 300.
The flow conditioner and gaskets are fitted between two pipe flange and the flow meter
flange å 7 .
Use only bolts which match to tehflange bolt hole and this will ensure that the correct positioning
of the plate can be found. The alignment notch must also be pointing in the same plane as the
transmitter.
Incorrect installation of the flow conditioner will have a small effect on the measurement accuracy.

• 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.
• The use of other types of flow conditioners, other than the Endress+Hauser flow conditioner, with

4.1 Cable specifications
4.1.1 PROFIBUS DP cable specifications
Cable type
Two versions of the bus line are specified in IEC 61158. Cable type A can be used for all
transmission rates up to 12 Mbit/s.
Cable type A
Characteristic impedance 135 to 165 at a measuring frequency of 3 to 20 MHz
Cable capacitance < 30 pF/m
Core cross-section > 0.34 mm
Cable type Twisted in pairs, 1 × 2, 2 × 2 or 1 × 4 wire
Loop-resistance 110 /km
Signal damping Max. 9 dB over the entire length of the cable section
Shielding Copper braided shielding or braided shielding and foil shielding
, corresponds to AWG 22
Bus structure
Note the following points:
• The maximum line length (segment length) depends on the transmission rate.
For cable type A, the maximum line length (segment length) is as follows:
Transmission rate [kBit/s] 9.6 to 93.75 187.5 500 1500 3000 to 12 000
Line length [m]([inch]) 1200 (4000) 1 000 (3 300) 400 (1300) 200 (650) 100 (330)
• A maximum of 32 users are permitted per segment.
• Each segment is terminated at either end with a terminating resistor.
• The bus length or the number of users can be increased by introducing a repeater.
• The first and last segment can comprise max. 31 devices.
The segments between the repeaters can comprise max. 30 stations.
• The maximum distance between two bus users can be calculated as follows:
(NO_REP + 1) × segment length
Note!
!
NO_REP = maximum number of repeaters that may be switched in series depending on the
repeater in question.
Example
In accordance with manufacturer specifications, 9 repeaters can be switched in series when using
a standard line. The maximum distance between two bus users at a transmission rate of
1.5 MBit/s can be calculated as follows: (9 + 1) × 200 m = 2000 m
Endress+Hauser 27
Wiring Proline t-mass 65 PROFIBUS DP/PA
Spurs
Please note the following:
• Length of spurs < 6.6 m (21.7 ft) (at max. 1.5 MBit/s)
• No spurs should be used for transmission rates >1.5 MBit/s. The line between the connector and
the bus driver is described as a spur. Experience has shown that you should proceed with caution
when configuring spurs. For this reason, you cannot presume that the sum of all spurs at
1.5 MBit/s may be 6.6 m (21.7 ft). This is affected greatly by the arrangement of the field devices.
Therefore, we recommend you do not use any spurs, if possible, at transmission rates
>1.5 MBit/s.
• If you cannot avoid using spurs, then they may not include any bus terminators.
Bus termination
It is important to terminate the RS485 line correctly at the start and end of the bus segment since
impedance mismatch results in reflections on the line which can cause faulty communication
ä 45.
Further information
General information and further notes regarding the wiring can be found in BA034S/04:
"Guidelines for planning and commissioning, PROFIBUS DP/PA, field communication".
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
ground, the shield of the bus cable is grounded many times. Ensure that the stripped and twisted
lengths of cable shield to the ground terminal are 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, it is therefore recommended - in the case of
systems without potential equalization - to connect the cable shield directly to the building ground
(or protective ground) at one end only and to use capacitive coupling to connect all other grounding
points.
Caution!
"
The statutory EMC requirements are only met if the cable shield is grounded at both ends!
