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 Intended 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 in applications
where there is an increased risk due to process pressure, are marked 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.
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 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.

Safety instructions Flowmeter Proline 300
8 Endress+Hauser
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
When working on and with the device:
‣Wear the required personal protective equipment as per national regulations.
2.4 Operational safety
Risk of injury!
‣Operate the device only if it is in proper technical condition, free from errors and faults.
‣The operator is responsible for the 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
