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.

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 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.

2.2.11 Thermal insulation
If the gas is very moist or saturated with water (e.g. biogas), the piping and the sensor housing
should be insulated to prevent droplets of liquid condensing on the pipe wall and/or the sensors.
In the event of extreme moisture and fluctuations in temperatures, it can help to provide a trace
heating system for the piping and/or the sensor.
2.2.12 Vibrations
"Caution!
Excessive vibrations can result in mechanical damage to the measuring device and its holder.
• Accelerations up to 1 g, 10 to 150 Hz, in accordance with IEC 60068-2-6, are permitted

4.2 Terminating resistors
!Note!
If the measuring device is used at the end of a bus segment, termination is required.
This can be performed in the measuring device by setting the terminating resistors on the I/O
board. Generally, however, it is recommended to use an external bus terminator and not
perform termination at the measuring device itself.
Has to be set for measuring devices with the following communication methods:
• PROFIBUS DP
– Baudrate ≤ 1.5 MBaud →Termination can be performed at the measuring device, see
graphic
– Baudrate > 1.5 MBaud →An external bus terminator must be used
• MODBUS RS485 →Termination can be performed at the measuring device, see graphic
#Warning!
Risk of electric shock! Risk of damaging the electronic components!
• All the safety instructions for the measuring device must be observed and all the warnings
heeded →Page 3.
• Use a workspace, working environment and tools purposely designed for electrostatically
sensitive devices.
