DESCRIPTION
The Magnetrol® Model R82 is an economical, loop-powered radar transmitter bringing radar to everyday applications. Applications that have been considered for ultrasonic can now utilize the superior performance of radar technology. The electronics are housed in a compact, single compartment cast aluminum or Lexan® housing. The R82 measures effectively even when atmospheres above the liquid are saturated with vapor. Pulse Burst technology and advanced signal processing manage common disturbances such as false echoes caused by obstructions, multi-path reflections from tank sidewalls or turbulence caused by agitators, aggressive chemicals, or aerators.

Application
MEDIA: Liquids and slurries; hydrocarbons to water based media (dielectric 1.7–100).
VESSELS: Most effective in storage vessels up to rated temperature and pressure. Pits and sumps, metallic and non-metallic tanks, others including plastic, glass-lined and concrete.
CONDITIONS: Virtually all level measurement and control applications including process conditions exhibiting varying specific gravity and dielectric, visible vapors, high fill/empty rates and some turbulence.
MARKETS: All process markets including replacement of loop-powered, ultrasonic transmitters.
