2 Safety instructions
2.1 Requirements for the personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill
the following requirements:
‣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.
The operating personnel must fulfill the following requirements:
‣Are instructed and authorized according to the requirements of the task by the facility's
owner-operator.
‣Follow the instructions in this manual.
2.2 Designated use
Application and media
The measuring device described in this manual is intended only for the 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 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→  6.
‣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.

Proline Promass E 100 Modbus RS485 Safety instructions
Endress+Hauser 9
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
The electronics and the medium may cause the surfaces to heat up. This presents a
burn hazard!
‣For elevated fluid temperatures, ensure protection against contact to prevent burns.
LWARNING
Danger of housing breaking due to measuring tube breakage!
If a measuring tube ruptures, the pressure inside the sensor housing will rise according to
the operating process pressure.
‣Use a rupture disk.
LWARNING
Danger from medium escaping!
For device versions with a rupture disk: medium escaping under pressure can cause injury
or material damage.
‣Take precautions to prevent injury and material damage if the rupture disk is actuated.
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:
‣Due to the increased risk of electric shock, gloves must be worn.
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.
Conversions to the device
Unauthorized modifications to the device are not permitted and can lead to unforeseeable
dangers.
‣If, despite this, modifications are required, consult with Endress+Hauser.
Repair
To ensure continued operational safety and reliability,
‣Carry out repairs on the device only if they are expressly permitted.
‣Observe federal/national regulations pertaining to repair of an electrical device.
‣Use original spare parts and accessories from Endress+Hauser only.

tube, avoid the following mounting locations in the pipe:
• Highest point of a pipeline.
• Directly upstream of a free pipe outlet in a down pipe.
Installation in down pipes
However, the following installation suggestion allows for installation in an open vertical
pipeline. Pipe restrictions or the use of an orifice with a smaller cross-section than the
nominal diameter prevent the sensor running empty while measurement is in progress.

Orientation
The direction of the arrow on the sensor nameplate helps you to install the sensor
according to the flow direction (direction of medium flow through the piping).

1) This orientation is recommended to ensure self-draining.
2) Applications with low process temperatures may decrease the ambient temperature. To maintain the
minimum ambient temperature for the transmitter, this orientation is recommended.
3) Applications with high process temperatures may increase the ambient temperature. To maintain the
maximum ambient temperature for the transmitter, this orientation is recommended.
If a sensor is installed horizontally with a curved measuring tube, match the position of the
sensor to the fluid properties.

1 Avoid this orientation for fluids with entrained solids: Risk of solids accumulating.
2 Avoid this orientation for outgassing fluids: Risk of gas accumulating.

6.1.2 Environmental and process requirements
Ambient temperature range
Measuring device • –40 to +60 °C (–40 to +140 °F)
• Order code for "Test, certificate", option JM:
–50 to +60 °C (–58 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.
System pressure
It is important that cavitation does not occur, or that gases entrained in the liquids do not
outgas.
Cavitation is caused if the pressure drops below the vapor pressure:
• In liquids that have a low boiling point (e.g. hydrocarbons, solvents, liquefied gases)
• In suction lines
‣Ensure the system pressure is sufficiently high to prevent cavitation and outgassing.
For this reason, the following mounting locations are recommended:
• At the lowest point in a vertical pipe
• Downstream from pumps (no danger of vacuum)
A0028777
Thermal insulation
In the case of some fluids, it is important to keep the heat radiated from the sensor to the
transmitter to a low level. A wide range of materials can be used for the required
insulation.
