2 Basic safety instructions
2.1 Requirements for the personnel
The personnel must fulfill the following requirements for its tasks:
‣Trained, qualified specialists must have a relevant qualification for this specific function
and task
‣Are authorized by the plant owner/operator
‣Are familiar with federal/national regulations
‣Before beginning work, the specialist staff must have read and understood the instructions
in the Operating Instructions and supplementary documentation as well as in the
certificates (depending on the application)
‣Following instructions and basic conditions
2.2 Designated use
Application and media
The measuring device described in these Instructions is intended only for flow measurement
of liquids and gases.
Depending on the version ordered, the measuring device can also measure potentially
explosive, flammable, poisonous and oxidizing media.
Measuring devices for use in hazardous areas, in hygienic applications or in applications
where there is an increased risk due to process pressure, are labeled accordingly on the
nameplate.
To ensure that the measuring device remains in proper condition for the operation time:
‣Only use the measuring device in full compliance with the data on the nameplate and the
general conditions listed in the Operating Instructions and supplementary documentation.
‣Based on the nameplate, check whether the ordered device is permitted for the intended
use in the hazardous area (e.g. explosion protection, pressure vessel safety).
‣Use the measuring device only for media against which the process-wetted materials are
adequately resistant.

CNGmass Basic safety instructions
Endress+Hauser 7
‣If the measuring device is not operated at atmospheric temperature, compliance with the
relevant basic conditions specified in the associated device documentation is absolutely
essential: "Device documentation" section →  11.
Incorrect use
Non-designated use can compromise safety. The manufacturer is not liable for damage caused
by improper or non-designated use.
LWARNING
Danger of breakage of the measuring tube due to corrosive or abrasive fluids.
Housing breakage due to mechanical overload possible!
‣Verify the compatibility of the process fluid with the measuring tube material.
‣Ensure the resistance of all fluid-wetted materials in the process.
‣Observe the specified pressure and temperature range.
Verification for borderline cases:
‣For special fluids and fluids for cleaning, Endress+Hauser is glad to provide assistance in
verifying the corrosion resistance of fluid-wetted materials, but does not accept any
warranty or liability as minute changes in the temperature, concentration or level of
contamination in the process can alter the corrosion resistance properties.
Residual risks
The external surface temperature of the housing can increase by max. 20 K due to the power
consumption of the electronic components. Hot process fluids passing through the measuring
device will further increase the surface temperature of the housing. The surface of the sensor,
in particular, can reach temperatures which are close to the fluid temperature.
Possible burn hazard due to fluid temperatures!
‣For elevated fluid temperature, ensure protection against contact to prevent burns.
2.3 Workplace safety
For work on and with the device:
‣Wear the required personal protective equipment according to federal/national
regulations.
For welding work on the piping:
‣Do not ground the welding unit via the measuring device.
If working on and with the device with wet hands:
‣It is recommended to wear gloves on account of the higher risk of electric shock.
2.4 Operational safety
Risk of injury.
‣Operate the device in proper technical condition and fail-safe condition only.
‣The operator is responsible for interference-free operation of the device.

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 meets general safety standards and legal requirements. It also complies with the EC
directives listed in the device-specific EC Declaration of Conformity. Endress+Hauser confirms
this by affixing the CE mark to the device.
2.6 IT security
We only provide a warranty if the device is installed and used as described in the Operating
Instructions. The device is equipped with security mechanisms to protect it against any
inadvertent changes to the device settings.
IT security measures in line with operators' security standards and designed to provide
additional protection for the device and device data transfer must be implemented by the
operators themselves.
Endress+Hauser can be contacted to provide support in performing this task.

6.1 Installation conditions
No special measures such as supports are necessary. External forces are absorbed by the
construction of the device.
6.1.1 Mounting position
Inlet and outlet runs
No special precautions need to be taken for fittings which create turbulence, such as valves,
elbows or T-pieces, as long as no cavitation occurs .
A0015597 A0015598
For the dimensions and installation lengths of the device, see the "Technical Information"
document, "Mechanical construction" section
6.1.2 Requirements from environment and process
Ambient temperature range
Measuring device –40 to +60 °C (–40 to +140 °F)
Safety Barrier Promass 100 –40 to +60 °C (–40 to +140 °F)
‣If operating outdoors:
Avoid direct sunlight, particularly in warm climatic regions.
Vibrations
The high oscillation frequency of the measuring tubes ensures that the correct operation of
the measuring system is not influenced by plant vibrations.
6.1.3 Special mounting instructions
Rupture disk
Make sure that the function and operation of the rupture disk is not impeded through the
installation of the device. The position of the rupture disk is indicated on a sticker applied over
it. If the rupture disk is triggered, the sticker is destroyed. The disk can therefore be visually
monitored. For additional information that is relevant to the process .

For detailed information about using a rupture disk, refer to the Operating Instructions
for the device on the CD-ROM provided
Zero point adjustment
All measuring devices are calibrated in accordance with state-of-the-art technology.
Calibration takes place under reference conditions . Therefore, a zero point adjustment in the
field is generally not required.
Experience shows that zero point adjustment is advisable only in special cases:
• To achieve maximum measuring accuracy even with low flow rates
• Under extreme process or operating conditions (e.g. very high process temperatures or very
high-viscosity fluids).
6.2 Mounting the measuring device
6.2.1 Required tools
For sensor
For flanges and other process connections: Corresponding mounting tools
6.2.2 Preparing the measuring device
1. Remove all remaining transport packaging.
2. Remove any protective covers or protective caps present from the sensor.
3. Remove stick-on label on the electronics compartment cover.

7.1.4 Shielding and grounding
The shielding and grounding concept requires compliance with the following:
• Electromagnetic compatibility (EMC)
• Explosion protection
• Personal protection equipment
• National installation regulations and guidelines
• Observe cable specification →  17.
• Keep the stripped and twisted lengths of cable shield to the ground terminal as short as
possible.
• Seamless cable shielding.
Grounding of the cable shield
To comply with EMC requirements:
• Ensure the cable shield is grounded to the potential matching line at multiple points.
• Connect every local ground terminal to the potential matching line.
NOTICE
In systems without potential matching, the multiple grounding of the cable shield causes
mains frequency equalizing currents!
Damage to the bus cable shield.
‣Only ground the bus cable shield to either the local ground or the protective ground at one
end.
