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.

• 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 may only be modified or repaired if such work is expressly permitted

in the Operating Instructions (on the CD-ROM).

• 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.

• Observe the technical data on the nameplate!

• The specialists must ensure that the measuring device has been wired correctly in accordance

with the wiring diagrams. The measuring device must be grounded if special protective

measures have not been taken, e.g. galvanically isolated power supply, SELV or PELV! (SELV

= Safe Extra Low Voltage; PELV = Protective Extra Low Voltage)

•

ith 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/../..).

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

• Avoid the formation of condensation in the area of the sensors.

• Take the properties of the gas or gas mixture into account (dryness, cleanliness, stability,

components 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 Pipe/pipe connection requirements

• The aim is to have a smooth inner pipe surface end to end.

Further information is provided in ISO Standard 14511.

"Caution!

The piping must be free from contamination and particles to avoid damage to the sensing

elements.

2.2.4 Inlet/outlet runs

The sensitivity of the thermal measuring principle to low flow rates means the flowmeter can

also be sensitive to internal disturbances in the flowing gas stream (e.g. vortex formation),

especially in pipes with larger 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 Further information is provided in ISO Standard 14511.

Please observe the following recommended minimum values with regard to the inlet and outlet

runs.

Regardless of any other consideration, the minimum recommendations for inlet and outlet runs

on either side of the sensor are:

Inlet run

15 x DN for the flanged version and 20 x DN for the insertion version

Outlet run

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

These are minimum values. The performance of the measuring device is often improved by using

longer runs.

!Note!

• 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 recommended to install control valves downstream of the measuring device.

• For very light gases such as Helium and Hydrogen all upstream distances should be doubled.

2.2.5 Perforated plate flow conditioner

It is recommended to install a perforated plate flow conditioner if the recommended inlet runs

cannot be observed.

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

plate flow conditioner.

2.2.6 Adjustable insertion depth for the insertion version

Please take the following three dimensions into account when installing the sensor:

!Note!

All the guidelines and information on the insertion depth refer to a standard welding nozzle

provided by Endress+Hauser.

It is important that the sensor be installed so that the top of the adjustable fitting is aligned with

the value on the scale that is equal to the following calculated value:

• (0.3 x a) + b + c + 2 mm (0.079 inch)

2.2.7 Aligning the flanged version

The arrows on the sides of the sensor housing must point in the same direction as the flow.

2.2.8 Aligning the insertion version

Once the sensor is set for the right immersion depth, it now has to be correctly aligned to the

flow direction. After aligning, the pipe union must be tightened to secure and seal the insert pipe.

Tighten the two safety screws.

#Warning!

The following tightening torques must be observed for the pipe union:

- Counter nut: hand-tight, then 1¼ revolutions with a wrench

- Safety screws: 5 Nm (3.89 lbf ft)

A0007535

a. Internal diameter for round pipes.

Duct height for a square duct if the sensor is to be

installed vertically or the duct width if it is to be

installed horizontally. (a = min. 80 mm / 3")

b. Thickness of the pipe wall or duct wall

c. Depth of the welding nozzle at the pipe or duct

including the sensor pipe union and low pressure

mounting set (if used).

The sensor cannot automatically detect the flow direction. These specifications only ensure that

the device is installed and aligned correctly.

2.2.9 Insertion version with low-pressure mounting set

Installation instructions for the insertion version with low-pressure mounting set

→ see Operating Instructions on the CD-ROM.

2.2.10 Temperature range

Install the sensor away from direct sunlight and extremes of temperature.

A0007536

The arrows on either side of the transmitter housing must

point in the direction of flow.

The graduated scale on the insert pipe must point to the

flow inlet side.

A0007537

Weld the welding nozzle onto the pipeline or duct. Align

the sensor (sensing element) at a 90 ° angle to the

direction of flow.
