0911472255The Flowline LR81 80GHz Pulse Radar Level Transmitter is a high-performance non-contact continuous level measurement instrument engineered by Flowline (USA) specifically for demanding bulk solids, fine powders, aggregates, and liquid storage applications in tall silos, hoppers, and process vessels. In dusty solid environments—such as cement powder, fly ash, lime, plastic pellets, grains, animal feed, and fertilizers—heavy dust generation and uneven material surfaces pose severe measurement challenges for traditional ultrasonic or lower-frequency radar sensors. The LR80's high-frequency 80GHz radar technology overcomes these hurdles by generating a powerful, short-wavelength signal that effortlessly penetrates dense dust clouds without being affected by air movement, pressure, or temperature shifts inside the vessel.
The Flowline LR81 features an ultra-narrow 4-degree beam angle that directs signal energy straight down to the material surface, effectively eliminating false echo interference caused by internal vessel walls, ladders, or structural bracing. Available with an optional adjustable swivel flange alignment system, operators can easily aim the radar beam directly at the discharge cone angle of the silo, ensuring maximum signal reflection and reliable measurement even when material angles of repose slope dramatically during filling or emptying cycles.
Equipped with a standard 2-wire 4-20mA HART output signal, the LR81 integrates wireless Bluetooth technology for effortless setup and diagnostics. Maintenance engineers can configure measuring ranges, adjust response times, and analyze live echo curves using the intuitive Flowline WebCal app on iOS or Android devices. Featuring a rugged IP68/NEMA 6P submersible enclosure and global dust-ignition proof / intrinsically safe explosion approvals (ATEX/IECEx), the Flowline LR81 delivers superior operational reliability for cement, mining, agriculture, plastics, and chemical processing industries.
