‣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 measured materials
The measuring device described in these Operating Instructions is intended for the
continuous, contact-less level measurement of liquids. The device must be installed in metallic
stilling wells. Operation is completely harmless to humans and animals.
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 labeled accordingly on the
nameplate.
To ensure that the measuring device remains in proper condition for the operation time:
‣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.
‣Check the nameplate to verify if the device ordered can be put to its intended use in the
approval-related area (e.g. explosion protection, pressure vessel safety).
‣Use the measuring device only for media against which the process-wetted materials are
adequately resistant.
‣If the measuring device is not operated at atmospheric temperature, compliance with the
relevant basic conditions specified in the associated device documentation is absolutely
essential.
‣Protect the measuring device permanently against corrosion from environmental
influences.
‣Observe the limit values in the "Technical Information".
The manufacturer is not liable for damage caused by improper or non-designated use.
Residual risk
During operation the sensor may assume a temperature near the temperature of the
measured material.
Danger of burns due to heated surfaces!
‣For high process temperatures: Install protection against contact in order to prevent burns.

‣Use original spare parts and accessories from the manufacturer only.
Hazardous area
To eliminate a danger for persons or for the facility when the device is used in the hazardous
area (e.g. explosion protection, pressure vessel safety):
‣Based on the nameplate, check whether the ordered device is permitted for the intended
use in the hazardous area.
‣Observe the specifications in the separate supplementary documentation that is an integral
part of these Instructions.
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.
NOTICE
Loss of degree of protection by opening of the device in humid environments
‣If the device is opened in a humid environment, the degree of protection indicated on the
nameplate is no longer valid. This may also impair the safe operation of the device.

5 Installation
5.1 Installation conditions
5.1.1 Conditions for the stilling well
• Metal (no enamel coating)
• Constant diameter (no rectangular stilling wells)
• Weld seam as smooth as possible
• For best radar propagation behavior it is recommended to have holes instead of slots. If
slots can not be avoided, they should be as thin and short as possible.
• Maximum gap between antenna/horn and wall of the stilling well: 5 mm (0.2 in).
• At any transition (e.g. when using a ball valve or mending pipe segments) gaps must not
exceed 1 mm (0.04 in).
• The stilling well must be smooth on the inside. Average roughness ≤ 6.3 µm (0.248 µin)
• Length and number of the holes do not affect the measurement. The hole diameter
(deburred) can be 1/7 of the well diameter, but should not exceed 25 mm (1 in).
• An increase of the pipe diameter is possible if the minimum lengths according to the
following figure and table are taken into account:
