Endress+Hauser 5
2 Safety instructions
2.1 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, Nm3sft3). At the same time, it also measures
gas 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 In such
cases, please contact your Endress+Hauser sales center for clarification. The use with unsta-
ble gases or gases not deemed to be suitable by Endress+Hauser must be avoided. The mea-
suring 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 dam-
ages being produced from this.
2.2 Installation, commissioning and operation
Note the following points:
• Installation, connection to the electricity supply, commissioning, operation and mainte-
nance of the measuring device must be carried out by trained, qualified specialists autho-
rized 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 con-
tain.
• 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 tem-
perature, concentration or the degree of contamination in the process can result in
changes of the chemical resistance properties. Therefore, Endress+Hauser can not guar-
antee or accept liability for the chemical resistance properties of the fluid wetted materials
in a specific application. The operator 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 device is correctly wired in accordance with
the wiring diagrams. The transmitter must be grounded unless special protection mea-
sures 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

2.3 Operational safety
Note the following points:
• Measuring devices for use in hazardous environments are accompanied by separate "Ex
documentation", which is an integral part of these Operating Instructions. Strict compli-
ance with the installation instructions and ratings as stated in this supplementary docu-
mentation is mandatory.
The symbol on the front of this supplementary Ex documentation indicates the approval
and the certification body (e.g. 0Europe, 2USA, 1Canada).
• Burn hazard! 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 tem-
peratures 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 mea-
suring devices used in Category II or III installations in accordance with the Pressure Equip-
ment Directive.
• The manufacturer reserves the right to modify technical data without prior notice. Your
Endress+Hauser sales center will supply you with current information and updates to
these Operating Instructions.
2.4 Return
• Do not return a measuring device if it is not absolutely certain that it has been fully cleaned
of all traces of hazardous substances, e.g. substances which have penetrated crevices or
diffused through plastic.
• Costs incurred for waste disposal and injury (burns, etc.) due to inadequate cleaning of the
measuring device will be charged to the owner-operator.
• Refer to the measures on →109.
2.5 Product safety
This measuring device is designed in accordance with good engineering practice to meet
state-of-the-art safety requirements, has been tested, and left the factory in a condition in
which it is safe to operate. It complies with the applicable standards and regulations in accor-
dance with EN 61010-1 "Safety requirements for electrical equipment for measurement,
control and laboratory use". It can, however, be a source of danger if used incorrectly or for
other than the designated use.

4.1 Incoming acceptance, transport and storage
4.1.1 Incoming acceptance
On receipt of the goods, check the following points:
• Is the packaging or content undamaged?
• Is the delivery complete and do the delivered goods match your order?
4.1.2 Transport
Observe the following instructions when unpacking and transporting the device to its final
location:
• Transport the measuring device in the container in which it is delivered.
• The covers or caps fitted to the process connections prevent mechanical damage to the
sealing surfaces and contamination in the measuring tube when the unit is being trans-
ported or in storage. Do not remove these covers or caps until immediately before instal-
lation.
• Do not lift measuring devices of nominal diameters > DN 40 (1½") by the transmitter hous-
ing or the connection housing in the case of the remote version →4. For transportation
purposes, 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.
When transporting, make sure that the measuring device does not unexpectedly turn
around its axis or slip.
A0004294
Fig. 4: Instructions for transporting sensors with > DN 40 (> 1½")
4.1.3 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 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.

Installation Proline t-mass 65 PROFIBUS DP/PA
12 Endress+Hauser
4.2 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 →116 and the medium temperature
range →116 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.
4.2.1 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
can be found in the "Documentation" section on →122.
4.2.2 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 mea-
surement 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.

Endress+Hauser 13
4.2.3 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 in) for diameters < DN 200 (8")
– 3 mm (0.12 in) for diameters DN 200 (8")
Further information is provided in ISO Standard 14511.
"Caution!
New installations should be free of metallic and abrasive particles to prevent damage to the
sensing elements on start-up.

or condensate are likely to be present. Mount the sensor in a position as indicated below
pIf the gas is very wet or saturated with water (e. g. biogas, undried compressed air), mount in inclined orien-
tation (approx. 135° ±10°).

4.2.5 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 ISO Standard 14511.
!Note!
• Where two or more flow disturbances are located upstream of the meter, the longest indi-
cated inlet length should prevail. For example if a control valve is additionally mounted
upstream from the measuring device and an elbow on the inlet side, select the recom-
mended inlet length for control valves: 50 × DN
• For very light gases such as Helium and Hydrogen all upstream distances should be dou-
bled.
The minimum recommendations for inlet and outlet runs (without flow conditioner) are:
Flanged sensor
Insertion sensor
!Note!
A specially designed perforated plate flow conditioner can be installed if it is not possible to
observe the inlet runs required (→16).

Outlet runs with pressure measuring points
The pressure measuring point should be installed downstream of the measuring device, so
that there is no potential influence of the pressure transmitter process connection on the
flow entering the measuring point.

Perforated plate flow conditioner
It is recommended to install a perforated plate flow conditioner if the recommended inlet
runs are not available.

Flow conditioner for use with insertion sensors 65I
→90
The well known "Mitsubishi" design is recommended for this application DN 80 mm to
DN 300 mm (3" to 12"). The flow conditioner must be installed at a distance of 8 × DN
upstream of the sensor. A further 5 pipe diameters minimum inlet run is required upstream
of the actual conditioner itself.
Measured errors can occur depending on disturbances in the inlet run. Therefore it is advis-
able to choose inlet runs that are as long as possible.
!Note!
In the case of insertion devices, the inlet run selected downstream of the conditioner should
be as long as possible.

Perforated plate flow conditioners (19 hole) for use with flanged sensor 65F →90
This is a special Endress+Hauser version designed especially 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 the pipe flange and the measuring
device →7. Use only standard bolts which match the flange bolt hole to guarantee that
the flow conditioner is centered correctly.
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.

1=perforatedplateflowconditioner,2= aeal/gasket,3= alignment notch, 4 = alignment in the same plane as the transmitter
Note
• Order the t-mass F sensor and the flow conditioner together to ensure that they are cali-
brated together. Joint calibration guarantees optimum performance. Ordering the flow
conditioner separately and using it with the measuring device will further increase mea-
surement uncertainty.
• The use of conditioners from other suppliers will affect the flow profile and pressure drop
and will have an adverse effect on performance.
• Bolts, nuts, seals, etc. are not included in the scope of supply and must be supplied by the
customer.

4.2.6 Heating
Some applications require suitable measures to avoid heat loss (condensation). Heating can
be electric, e. g. with heated elements, or by means of hot water, steam pipes or insulation.
"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.
4.2.7 Thermal insulation
When the gas is very damp or saturated with water (e. g. bio gas), the piping and flowmeter
body should be insulated to prevent water droplets condensing on the measuring sensor.

4.3 Installation
4.3.1 Mounting the insertion sensor
The sensor can be mounted into a welding socket or a retractable mounting set. If a retract-
able mounting set is being used, then refer to the supplementary documentation delivered
with the mounting set.
Mounting the welding socket
This instruction describes mounting of the Endress+Hauser welding socket. If a welding boss
is already available or a customer-specific one is being used, then go to the next section
"Insertion depth calculation and adjustment."
!Note!
• Take the orientation and inlet and outlet runs into account before mounting the welding
socket→14 ff.
• The welding socket is made of stainless steel 1.4404 (316/316L). Use appropriate weld-
ing technique.
"Caution!
• When mounting the fitting to a thin wall duct, use a suitable support bracket for the sensor
and weld the welding socket to a base plate to spread the load. Otherwise, the mounting
may be unstable and the duct wall can be damaged.
#Warning!
• These instructions are only applicable to installation in an un-pressurized line, without gas
present and at safe temperatures.
1. Drill or a cut hole of Ø 31.0 mm ± 0.5 mm (1.22 ± 0.019") in the pipe.
2. Deburr the hole.
3. Fit the edge of the welding socket into hole, align it vertically and weld it on →9.
A0010098

Insertion depth calculation and adjustment
To ensure optimum measurement performance, the insertion sensor must be installed in the
correct position in the pipe or duct (30% of the internal diameter).
A millimeter and inch scale is provided along the entire length of the sensor tube. This
makes it possible to align the sensor at the right depth.
4. Calculate the insertion depth:
– with the help of the Quick Setup "Sensor" →52 or
– using the following dimensions and formulae
