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.
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 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).
‣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.
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.

2.6 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.

Proline 400 HART Product description
Endress+Hauser 9
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.
3 Product description
The measuring system consists of a transmitter and two or one sensor sets. The transmitter
and sensor sets are mounted in physically separate locations. They are interconnected by
sensor cables.
• Prosonic Flow I 400: The sensors work as sound generators and sound receivers. The
sensors in a sensor pair are always arranged opposite one another and send/receive the
ultrasonic signals directly (1-traverse positioning).
• Prosonic Flow W 400: The measuring system uses a method based on the time-of-flight
difference. Here, the sensors work as sound generators and sound receivers. Depending on
the application and version, the sensors can be arranged for a measurement via 1, 2, 3 or 4
traverses.
The transmitter serves to control the sensor sets, to prepare, process and evaluate the
measuring signals, and to convert the signals to the desired output variable.
