Proline t-mass 65 Safety instructions

Endress+Hauser 3

1 Safety instructions

1.1 Designated use

• The measuring device works based on the thermal measuring principle and is to be used

exclusively for measuring the mass flow of gases (e.g. kg, Nm3, Scf).

• The measuring device can be configured to measure pure gases (e.g. oxygen, nitrogen, carbon

dioxide, argon etc.) or gas mixtures (e.g. natural gas).

• Any use other than that described here compromises the safety of persons and the entire

measuring system and is, therefore, not permitted.

• The manufacturer is not liable for damage caused by improper or non-designated use.

1.2 Installation, commissioning and operation

• The measuring device must only be installed, connected, commissioned and maintained by

qualified and authorized specialists (e.g. electrical technicians) in full compliance with the

instructions in these Brief Operating Instructions, the applicable norms, legal regulations and

certificates (depending on the application).

• The specialists must have read and understood these Brief Operating Instructions and must

follow the instructions they contain. If you are unclear on anything in these Brief Operating

Instructions, you must read the Operating Instructions (on the CD-ROM). The Operating

Instructions provide detailed information on the measuring device.

• The measuring device should only installed in a de-energized state free from outside loads or

strain.

• The measuring device may only be modified if such work is expressly permitted in the

Operating Instructions (on the CD-ROM).

• Repairs may only be performed if a genuine spare parts kit is available and this repair work is

expressly permitted.

• If performing welding work on the piping, the welding unit may not be grounded by means

of the measuring device.

1.3 Operational safety

• The measuring device is designed 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. Relevant regulations

and European standards have been observed.

• 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.

• The information on the warning notices, nameplates and connection diagrams affixed to the

device must be observed. These contain important data on the permitted operating conditions,

the range of application of the device and information on the materials used.

• If the device is not used at atmospheric temperatures, compliance with the relevant marginal

conditions as specified in the device documentation supplied (on CD-ROM) is mandatory.

Safety instructions Proline t-mass 65

4Endress+Hauser

• The device must be wired as specified in the wiring and connection diagrams. Interconnection

must be permitted.

• All parts of the device must be included in the potential equalization of the system.

• Cables, certified cable glands and certified dummy plugs must be suitable to withstand the

prevailing operating conditions, such as the temperature range of the process. Housing

apertures that are not used must be sealed with dummy plugs.

• The device should only be used for fluids to which all the wetted parts of the device are

sufficiently resistant. With regard to special fluids, including fluids used for cleaning,

Endress+Hauser will be happy to assist in clarifying the corrosion-resistant properties of

wetted materials. However, minor changes in temperature, concentration or in the degree of

contamination in the process may result in variations in corrosion resistance. For this reason,

Endress+Hauser does not accept any responsibility with regard to the corrosion resistance of

wetted materials in a specific application. The user is responsible for the choice of suitable

wetted materials in the process.

• Hazardous areas

Measuring devices for use in hazardous areas are labeled accordingly on the nameplate.

Relevant national regulations must be observed when operating the device in hazardous areas.

The Ex documentation on the CD-ROM is an integral part of the entire device documentation.

The installation regulations, connection data and safety instructions provided in the Ex

documentation must be observed. The symbol on the front page indicates the approval and

certification body (0Europe, 2USA, 1Canada).

The nameplate also bears the documentation number of this Ex documentation

(XA***D/../..).

1.4 Safety conventions

#Warning!

"Warning" indicates an action or procedure which, if not performed correctly, can result in injury

or a safety hazard. Comply strictly with the instructions and proceed with care.

"Caution!

“Caution” indicates an action or procedure which, if not performed correctly, can result in

incorrect operation or destruction of the device. Comply strictly with the instructions.

!Note!

"Note" indicates an action or procedure which, if not performed correctly, can have an indirect

effect on operation or trigger an unexpected response on the part of the device.

2 Installation

2.1 Transporting to the measuring point

• Transport the measuring device to the measuring point in the original packaging.

• The covers or caps fitted on the process connections prevent mechanical damage to the

sensors during transport and storage. For this reason, do not remove the covers or caps until

immediately before installation.

2.2 Installation conditions

• The thermal dispersion principle is sensitive to disturbed flow conditions. Therefore, the

requirements and conditions for installation in this section are especially important

• Take measures to reduce or avoid condensation (e.g. install a condensation trap, thermal

insulation, etc.).

2.2.1 Dimensions

For the dimensions of the measuring device → see associated Technical Information on the

CD-ROM.

A0007408

Use slings around the process connections.

#Warning!

Risk of injury! The device can slip.

The center of gravity of the measuring device may be

higher than the holding points of the slings.

Always ensure that the device cannot slip or turn around

its axis.

A0007409

Do not lift measuring devices by the transmitter housing

or the connection housing in the case of the remote

version. Do not use chains as they could damage the

housing.

2.2.2 Pipework requirements

Good engineering practice should be followed at all times.

Further information is provided in ISO Standard 14511.

!Note!

Measuring errors will result due to a mismatch of the pipes or gaskets.

2.2.3 Orientation

Make sure that the direction arrow on the sensor matches the direction of gas flow through the

pipe.

2.2.4 Inlet/outlet runs

The thermal dispersion principle is sensitive to disturbed flow conditions.

As a general rule, the installed thermal flow sensor should always be installed as far away as

possible from any flow disturbances. Further information is provided in ISO Standard 14511.

m In the case of saturated or unclean gases, upward flow in a vertical pipe section is preferred to minimize

condensation/contamination.

n Not recommended if the vibrations are too high or if the installation is unstable.

o Only suitable for clean/dry gases. On horizontal pipes do not mount the sensor from the bottom, if the gas is very damp

or saturated with water (e. g. Bio Gas). Mount the sensor in a position as indicated below (α=135°).

Outlet run

2 x DN for the flanged version and 5 x DN for the insertion version

!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.

• A specially designed perforated plate flow conditioner can be installed if it is not possible to

observe the inlet runs required.

Please refer to the Operating Instructions on the CD-ROM for special details on the perforated

plate flow conditioner
