The FCC announced on Tuesday that they are expanding the scope of the proceeding proposed to cover Tank Level Probing Radar (TLPR) devices, originally applicable only to devices operating in the 77-81 GHz band, and contained within steel or concrete tanks. Citing requests for waivers and other inquiries as evidence of the increasing demand for a comprehensive set of guidelines for general level probing radar (LPR), to allow the use outdoors and on other frequencies, the FCC is proposing an amendment to Part 15 rules that would apply to the operation of LPR devices installed in both open-air environments and inside storage tanks in the following frequency bands: 5.925-7.250 GHz, 24.05-29.00 GHz, and 75-85 GHz.
Level probing radar applications are diverse but among the popular uses are process control systems used to measure the amount of various substances such as liquids and granulates.
