Electromagnetic compatibility and Radio spectrum Matters (ERM); Short Range Devices (SRD); Level Probing Radar (LPR) equipment operating in the frequency ranges 6 GHz to 8@5 GHz@ 24@05 GHz to 26@5 GHz@ 57 GHz to 64 GHz@ 75 GHz to 85 GHz; Part 2: Harmonize
The present document specifies the requirements for Level Probing Radar (LPR) applications based on pulse RF@ FMCW@ or similar wideband techniques. 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. LPR always consist of a combined transmitter and receiver and are used with an integral or dedicated antenna. The LPR equipment is for professional applications to which 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. The LPR applications in the present document are not intended for communications purposes.
