owner-operator.
‣Follow the instructions in this manual.
2.2 Intended 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
closed metallic tanks or reinforced concrete tanks, or similar enclosure structures made of
comparable attenuating material. 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.
