Exemplary Velocity Data Labasys® Control Ex ‘Bulk-Flow'

Exemplary Velocity Data

The shift connector allows to shift the tip of your Labasys® Control Ex 'Bulk-Flow' instrument to different measuring position in an operational and thus pressurized Spherizone plant. Lets you  monitor the velocity of your bulk flow at different positions with only one instrument.

Labasys® Control Ex ‘Bulk-Flow'

Approved by LyondellBasell for the velocity measurement  in the recirculation loop of the 'multi-zone circulating reactor' MZCR of their Spherizone (PP) & Hyperzone (PE) process.

Any kind of particulate bulk material flows in tubes or reactors with known direction of solid/gas or solid/liquid systems, e.g.:
  • Recirculation rate of polymer material in MZCR reactor of Spherizone (PP) & Hyperzone (PE) process 
  • Solids transport loops in Chemical Looping Combustion (CLC) for Carbon Capture and Storage (CCS) in carbonate, calciner thermal loop or in the oxygen transport loop.
