Introduction
In order to cover the requirements concerning the receiver requirements communicated by the European Commission
the present document is a revision of ETSI EN 302 372 V2.1.1 [i.13] a harmonised standard for Tank Level Probing
Equipment within the scope of the Directive 2014/53/EU [i.1]. The standard has been published in the OJEU without
restrictions on 10 March 2017 [i.6].
Unlike LPRs [i.7] the TLPRs are always configured to pre-drilled harmonised openings and flanges of the tanks. Thus,
with very small openings of e.g. a few centimetres most of the TLPR antennae cannot fulfil the characteristics as
required by ETSI EN 302 729-1 [i.7]. Since TLPRs are always installed on metallic tanks, TLPR manufactures have
greater freedom creating a TLPR architecture in order to suit the needs of its customers.

4 Technical requirements specifications
4.1 Environmental profile
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be in accordance with its intended use, but as a minimum, shall be that specified in the test
conditions contained in the present document. The equipment shall comply with all the technical requirements of the
present document at all times when operating within the boundary limits of the operational environmental profile
defined by its intended use.
4.2 Equipment categories
4.2.1 General
The present document covers Tank Level Probing Radar (TLPR) equipment for operation on tanks as outlined in the
scope (clause 1) of the present document.
Receive-only equipment exhibiting a receive only mode or a standby mode are not covered by the scope of the present
document.
NOTE: In addition, the manufacturer should consider further installation requirements as specified in Annex F
and should provide this information to the user/installer. These installation requirements, however, are not
subject to Annex A of the present document.
A categorization of this TLPR equipment category has been conducted based on:
• the operation in the Permitted Range of Operating Frequency(PROF), see clause 4.2.2;
• the available antenna connection, see clause 4.2.3.
4.2.2 Categorization by Permitted Range of Operating Frequency (PROF)
The categorization of TLPR equipment by the Permitted Range of Operation is used as given by Table 1.
Table 1: Categorization by frequency ranges
EUT category Permitted Range of
Operating Frequency
PROF 1 4,5 GHz ≤ f ≤ 7 GHz
PROF 2 8,5 GHz ≤ f ≤ 10,6 GHz
PROF 3 24,05 GHz ≤ f ≤ 27 GHz
PROF 4 57 GHz ≤ f ≤ 64 GHz
PROF 5 75 GHz ≤ f ≤ 85 GHz
This categorization of Permitted Range of Operating Frequency has been conducted, reflecting the different permitted
frequency ranges which can be used for Tank Level Probing Radars in accordance with Commission Implementing
Decision (EU) 2025/105 [i.5].
4.2.3 Categorization by antenna connection
Each of the TLPR equipment may or may not be equipped with an antenna connector, therefore the second
categorization is done by the kind of antenna connection:
• ANT1: TLPR equipment features an antenna connector - the equipment is equipped with a dedicated antenna
(AUT).
• ANT2: TLPR equipment has no antenna connector-the equipment is equipped with an integral antenna.

All of the categories are subject to these clause 4 requirements. Differentiation is made by test cases under clause 5.
An overview of the applicability of transmitter requirements and receiver requirements for the different TLPR

Introduction
In order to cover the requirements concerning the receiver requirements communicated by the European Commission
the present document is a revision of ETSI EN 302 372 V2.1.1 [i.13] a harmonised standard for Tank Level Probing
Equipment within the scope of the Directive 2014/53/EU [i.1]. The standard has been published in the OJEU without
restrictions on 10 March 2017 [i.6].
Unlike LPRs [i.7] the TLPRs are always configured to pre-drilled harmonised openings and flanges of the tanks. Thus,
with very small openings of e.g. a few centimetres most of the TLPR antennae cannot fulfil the characteristics as
required by ETSI EN 302 729-1 [i.7]. Since TLPRs are always installed on metallic tanks, TLPR manufactures have
greater freedom creating a TLPR architecture in order to suit the needs of its customers.

receiver and are equipped with an integral or dedicated antenna provided and specified by the equipment manufacturer.
Further details of the covered TLPR equipment can be found in clause 4.2 of the present document.
Technical and regulatory requirements for TLPR are provided in European Commission Implementing Decision (EU)

4 Technical requirements specifications
4.1 Environmental profile
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be in accordance with its intended use, but as a minimum, shall be that specified in the test
conditions contained in the present document. The equipment shall comply with all the technical requirements of the
present document at all times when operating within the boundary limits of the operational environmental profile
defined by its intended use.
4.2 Equipment categories
4.2.1 General
The present document covers Tank Level Probing Radar (TLPR) equipment for operation on tanks as outlined in the
scope (clause 1) of the present document.
Receive-only equipment exhibiting a receive only mode or a standby mode are not covered by the scope of the present
document.
NOTE: In addition, the manufacturer should consider further installation requirements as specified in Annex F
and should provide this information to the user/installer. These installation requirements, however, are not
subject to Annex A of the present document.
A categorization of this TLPR equipment category has been conducted based on:
• the operation in the Permitted Range of Operating Frequency(PROF), see clause 4.2.2;
• the available antenna connection, see clause 4.2.3.
4.2.2 Categorization by Permitted Range of Operating Frequency (PROF)
The categorization of TLPR equipment by the Permitted Range of Operation is used as given by Table 1.
Table 1: Categorization by frequency ranges
EUT category Permitted Range of
Operating Frequency
PROF 1 4,5 GHz ≤ f ≤ 7 GHz
PROF 2 8,5 GHz ≤ f ≤ 10,6 GHz
PROF 3 24,05 GHz ≤ f ≤ 27 GHz
PROF 4 57 GHz ≤ f ≤ 64 GHz
PROF 5 75 GHz ≤ f ≤ 85 GHz
This categorization of Permitted Range of Operating Frequency has been conducted, reflecting the different permitted
frequency ranges which can be used for Tank Level Probing Radars in accordance with Commission Implementing
Decision (EU) 2025/105 [i.5].
4.2.3 Categorization by antenna connection
Each of the TLPR equipment may or may not be equipped with an antenna connector, therefore the second
categorization is done by the kind of antenna connection:
• ANT1: TLPR equipment features an antenna connector - the equipment is equipped with a dedicated antenna
(AUT).
• ANT2: TLPR equipment has no antenna connector-the equipment is equipped with an integral antenna.
