(Main)Short Range Devices (SRD) - Tank Level Probing Radar (TLPR) equipment operating in the frequency ranges 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 - Harmonised Standard covering the essential requirements of article 3.2 of the Directive 2014/53/EU
Short Range Devices (SRD) - Tank Level Probing Radar (TLPR) equipment operating in the frequency ranges 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 - Harmonised Standard covering the essential requirements of article 3.2 of the Directive 2014/53/EU
The present document contains requirements to demonstrate that TLPR equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference.
TLPRs are used for tank level measurement applications in many industries concerned with process control to measure the amount of various substances (mostly liquids or granulates). TLPRs are used for a wide range of applications such as process control, custody transfer measurement (government legal measurements), water and other liquid monitoring,
spilling prevention and other industrial applications. The main purposes of using TLPRs are:
• to increase reliability by preventing accidents;
• to increase industrial efficiency, quality and process control;
• to improve environmental conditions in production processes.
The present document applies to TLPRs radiating RF signals towards 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 does not necessarily include all the characteristics, which may be required by a user, nor does it necessarily represent the optimum performance achievable, it applies only to TLPRs fitted with dedicated antennas.
TLPRs always consist of a combined transmitter and receiver and are used with an integral or dedicated antenna. The TLPR equipment is for professional applications where installation and maintenance are performed by professionally trained individuals only.
The scope is limited to TLPRs operating as Short Range Devices (SRD), 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.
The TLPR applications in the present document are not intended for communication purposes. Their intended usage excludes any intended radiation into free space.
Naprave kratkega dosega (SRD) - Oprema radarja za sondiranje nivoja v rezervoarjih (TLPR), ki deluje v frekvenčnih območjih od 4,5 GHz do 7 GHz, od 8,5 GHz do 10,6 GHz, od 24,05 GHz do 27 GHz, od 57 GHz do 64 GHz in od 75 GHz do 85 GHz - Harmonizirani standard, ki zajema bistvene zahteve člena 3.2 direktive 2014/53/EU
Ta dokument vključuje zahteve, s katerimi se dokazuje, da je oprema radarja za sondiranje nivoja v rezervoarjih (TLPR) izdelana tako, da učinkovito uporablja in podpira učinkovito rabo radijskega spektra z namenom preprečevanja škodljivega motenja.
Radarji za sondiranje nivoja v rezervoarjih se uporabljajo za merjenje nivoja v rezervoarjih v številnih industrijskih dejavnostih, povezanih z nadzorom procesov, pri čemer se izmeri količina različnih snovi (večinoma tekočin ali granulatov). Radarji za sondiranje nivoja v rezervoarjih se uporabljajo za različne namene, npr. za nadzor procesov, meritve pri prenosu skrbništva (zakonsko določene meritve), nadzor vode in drugih tekočin,
preprečevanje razlitja ter za druge vrste industrijske uporabe. Glavni nameni uporabe radarjev za sondiranje nivoja v rezervoarjih so:
• povečanje zanesljivosti s preprečevanjem nesreč;
• povečanje učinkovitosti, kakovosti in nadzora procesov v industriji;
• izboljšanje okoljskih pogojev v proizvodnih postopkih.
Ta dokument se uporablja za radarje za sondiranje nivoja v rezervoarjih, ki sevajo radiofrekvenčne signale proti površini snovi v zaprtem rezervoarju. Kakršno koli sevanje zunaj rezervoarja nastane zaradi puščanja in se upošteva kot nenamerno sevanje. Ta dokument ne vključuje nujno vseh lastnosti, ki bi jih morda potreboval uporabnik, in ne predstavlja nujno najboljšega mogočega delovanja; uporablja se samo za radarje za sondiranje nivoja v rezervoarjih, ki so nameščeni z namenskimi antenami.
Radarji za sondiranje nivoja v rezervoarjih so vedno opremljeni s kombiniranim oddajnikom in sprejemnikom ter se uporabljajo z vgrajeno ali namensko anteno. Oprema radarjev za sondiranje nivoja v rezervoarjih je namenjena za profesionalno uporabo, pri kateri namestitev in vzdrževanje izvajajo samo strokovno usposobljene osebe.
Področje uporabe je omejeno na radarje za sondiranje nivoja v rezervoarjih, ki delujejo kot naprave kratkega dosega (SRD), pri čemer so naprave nameščene v zaprtih kovinskih rezervoarjih ali rezervoarjih iz armiranega betona ali podobnih ohišjih, izdelanih iz primerljivo slabilnega materiala, v katerih je shranjena snov, tekočina ali prah.
Uporaba radarjev za sondiranje nivoja v rezervoarjih iz tega dokumenta ni namenjena za komunikacijo. Njihov predvideni namen uporabe izključuje kakršno koli namerno sevanje v okolje.

Foreword
This final draft Harmonised European Standard (EN) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM), and is now submitted for the Vote phase of the
ETSI standards EN Approval Procedure.
The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.8] to
provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation
of the laws of the Member States relating to the making available on the market of radio equipment and repealing
Directive 1999/5/EC [i.6].
Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with
the normative clauses of the present document given in table A.1 confers, within the limits of the scope of the present
document, a presumption of conformity with the corresponding essential requirements of that Directive and associated
EFTA regulations.
Proposed national transposition dates
Date of latest announcement of this EN (doa): 3 months after ETSI publication
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 6 months after doa
Date of withdrawal of any conflicting National Standard (dow): 18 months after doa
There have been no significant technical changes incorporated from the previous version of the present document.
