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 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.
