The present document specifies the requirements for Tank Level Probing Radar (TLPR) applications based on pulse RF,
FMCW, or similar wideband techniques.
The radar applications in the present document are limited to TLPRs operating as short range devices, in which the
devices are installed in closed metallic tanks or reinforced concrete tanks, or similar enclosure structures made of
comparable attenuating material, holding a substance, liquid or powder.
TLPRs are only used for tank level measurement applications where TLPRs are radiating RF signals directly from the
tank top downwards to the surface of a substance contained in a closed tank. Any radiation outside of the tank is caused
by leakage and is considered as unintentional emission.
The present document applies only to TLPRs fitted with integrated and dedicated antennas as given in table 1.

Equipment Frequency bands
TLPR
4,5 GHz to 7 GHz;
8,5 GHz to 10,6 GHz;
24,05 GHz to 27 GHz;
57 GHz to 64 GHz;
75 GHz to 85 GHz.
The present document is intended to cover the provisions of Directive 1999/5/EC (R&TTE Directive) [1], article 3.2,
which states that radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as to avoid harmful interference.
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of article 3 of the R&TTE Directive [1] may apply to equipment within the scope of the present
document.
NOTE: A list of such ENs is included on the web site: http://www.newapproach.org/.
