ČSN ETSI EN 302 372 V2.1.1 The present document applies to the following equipment types: Tank Level Probing Radar (TLPR) applications are based on pulse RF, FMCW or similar wideband techniques. 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. Table 1 shows a list of the frequency bands as assigned to Tank Level Probing Radars in the EC Decision 2013/752/EU [i.7] and CEPT/ERC Recommendation 70-03 [i.1] as known at the date of publication of the present document. 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.

ČSN ETSI EN 302 729 V2.1.1 The present document applies to the following equipment types: Level Probing Radar (LPR) applications are based on pulse RF, FMCW, or similar wideband techniques. The present document contains requirements to demonstrate that LPR equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference. Table 1 shows a list of the frequency bands as assigned to Level Probing Radars in the European Commission Decision 2013/752/EU [i.13] on harmonised deployment conditions for industrial Level Probing Radars (LPR) as known at the date of publication of the present document. Technical and regulatory requirements for LPR are provided in ECC Decision (11)02 [i.20], which are based on ECC Report 139 [i.8]. LPRs are used in many industries concerned with process control to measure the amount of various substances (mostly liquids or granulates). LPRs 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 LPRs are: - to increase reliability by preventing accidents; - to increase industrial efficiency, quality and process control; - to improve environmental conditions in production processes. LPRs always consist of a combined transmitter and receiver and are used with an integral or dedicated antenna. The LPR equipment is for professional applications where installation and maintenance are performed by professionally trained individuals only. NOTE: LPR antennas are always specific directive antennas and no LPR omnidirectional antennas are used. This is also important in order to limit the illuminated surface area as well as to control and limit the scattering caused by the edges of the surface. The scope is limited to LPRs operating as Short Range Devices (SRD). The LPR applications in the present document are not intended for communications purposes.
