摘要
The dynamic fluidized-bed level in an olefin polymerization reactor is determined by radar or ultrasound waves. Echoes are processed to take into account the turbulence caused by bubbles, which can be as large as four meters in diameter, bursting on the surface, expelling resin particles into the freeboard above the dynamic fluidized-bed level.
