2 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 starting work, read and understand the instructions in the manual and
supplementary documentation as well as the certificates (depending on the application).
‣Follow instructions and comply with basic conditions.
2.2 Designated use
Application and media
The measuring device described in this manual is intended only for the flow measurement of
liquids with a minimum conductivity of 5 µS/cm.
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 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:
‣Keep within the specified pressure and temperature range.
‣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 to which the process-wetted materials are
sufficiently resistant.
‣If the ambient temperature of the measuring device is outside the atmospheric
temperature, it is absolutely essential to comply with the relevant basic conditions as
specified in the device documentation.
‣Protect the measuring device permanently against corrosion from environmental
influences.
The measuring device is optionally tested in accordance with OIML R49: 2006 and has
an EC type-examination certificate according to Measuring Instruments Directive
2004/22/EC (MID) for service subject to legal metrological control ("custody transfer")
for cold water (Annex MI-001).
The permitted medium temperature in these applications is 0 to +50 °C (+32 to +122 °F).
Incorrect use
Non-designated use can compromise safety. The manufacturer is not liable for damage caused
by improper or non-designated use.

Safety instructions Flowmeter Proline 400
8 Endress+Hauser
LWARNING
Danger of breakage due to corrosive or abrasive fluids and ambient conditions!
‣Verify the compatibility of the process fluid with the sensor material.
‣Ensure the resistance of all fluid-wetted materials in the process.
‣Keep within the specified pressure and temperature range.
NOTICE
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
LWARNING
If the temperature of the media or electronics unit is high or low, this may cause the
surfaces of the device to become hot or cold. This poses a risk of burns or frostbite!
‣In the case of hot or cold medium temperatures, install appropriate protection against
contact.
2.3 Workplace safety
For work on and with the device:
‣Wear the required personal protective equipment according to 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:
‣Due to the increased risk of electric shock, wear suitable gloves.
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 EU
directives listed in the device-specific EU Declaration of Conformity. Endress+Hauser confirms
this by affixing the CE mark to the device.
Furthermore, the device meets the legal requirements of the applicable UK regulations
(Statutory Instruments). These are listed in the UKCA Declaration of Conformity along with
the designated standards.

2.6 IT security
Our warranty is valid only 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 settings.
IT security measures, which provide additional protection for the device and associated data
transfer, must be implemented by the operators themselves in line with their security
standards.
2.7 Device-specific IT security
The device offers a range of specific functions to support protective measures on the operator's
side. These functions can be configured by the user and guarantee greater in-operation safety
if used correctly.
For detailed information on device-specific IT security, see the Operating Instructions for
the device.
