4 Basic safety instructions
4.1 Requirements for 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.
‣
4.2 Designated use
Application and media
The measuring device described in these Operating Instructions is intended for continuous,
non-contact level measurement in liquids. Because of its operating frequency of approx.
26 GHz, a maximum radiated pulsed power of 5.7 mW and an average power output of
0.015 mW, use outside of closed, metallic vessels is also permitted. For operation outside of
closed vessels the device must be installed according to the instructions mentioned in the
chapter "Installation" → 19. Operation does not pose a risk to health or the environment.
If the limit values specified in the "Technical data" and the conditions listed in the instructions
and additional documentation are observed, the measuring device may be used for the
following measurements only:
Measured process variables: distance
‣
Calculated process variables: volume or mass in vessels of any shape; flow through
‣
measuring weirs or flumes (calculated from the level by the linearization functionality)
To ensure that the measuring device remains in proper condition for the operation time:
Use the measuring device only for media against which the process-wetted materials are
‣
adequately resistant.
Observe the limit values in "Technical data".
‣
Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
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.
Residual risks
Due to heat transfer from the process as well as power dissipation within the electronics, the
temperature of the electronics housing and the assemblies contained therein may rise to 80 °C
(176 °F) during operation. When in operation, the sensor can reach a temperature close to the
medium temperature.
Danger of burns from contact with surfaces!
For elevated fluid temperature, ensure protection against contact to prevent burns.

Caution!
The sensor cable is not designed as supporting cable. Do not use as a suspension wire.
7.1.2 Nozzle installation
The antenna should be just out of the nozzle for optimum measurement. The interior of the
nozzle must be smooth and may not contain any edges or welded joints. The edge of the
nozzle should be rounded if possible. The maximum nozzle length L depends on the nozzle
diameter D. Please note the specified limits for the diameter and length of the nozzle.

7.1.3 Orientation
A0028410
5Tank installation position
• If possible install the sensor so that its lower edge projects into the vessel.
• Do not install the sensor in the middle of the tank (2). We recommend leaving a distance
(1) between the sensor and the tank wall measuring 1/6 of the tank diameter.
Recommended distance A wall - nozzle outer edge: ~ 1/6 of the tank diameter D. However,
the device must not under any circumstances be mounted closer than 15 cm (5.91 in) to the
tank wall.
• Avoid measurements through the filling curtain (3).
• Avoid equipment (4) such as limit switches, temperature sensors, baffles, heating coils etc.
• Multiple devices can be operated in one tank without influencing each other.
• No signals are analyzed within the Blocking distance. It can therefore be used to suppress
interference signals (e.g. the effects of condensate) close to the antenna.
By default an automatic Blocking distance of at least 0.1 m (0.33 ft) is preset. However it
can be manually overwritten (even 0 m (0 ft) is allowed.
Automatic calculation:
Blocking distance = Empty calibration - Full calibration - 0.2 m (0.656 ft).
The Blocking distance parameter is recalculated according to this formula every time a new
value is entered into the Empty calibration parameter or Full calibration parameter.
If this calculation results in a value <0.1 m (0.33 ft), the blocking distance of 0.1 m (0.33 ft)
is used instead.
