Coriolis mass flowmeters

coriolis maseni mjerači protoka

When it comes to Coriolis mass meters, their supreme technology should not be a matter of price. Mass meter technology is based on the Coriolis principle. The mass flow of liquids and gases depends on the deviation of the measuring tubes caused by the flow of media. Also through the resonant frequency of vibrating tubes we can get the density of the medium. KROHNE Coriolis meters are characterized by high accuracy, even with very rapid changes in media temperature. Due to straight pipes, the pressure drop is minimized. Process temperature up to 400 ° C as well as pressure up to 100 bar.

Entrained Gas Management

KROHNE’s OPTIMASS series with Entrained Gas Management (EGMTM) functionality is the only range of meters to offer a solution for all flow conditions at a gas volume fraction (GVF) from 0 to 100%.

Today OPTIMASS Coriolis flowmeters with Entrained Gas Management can provide repeatable measurement in situations like:

  • liquids mixed with gas
  • slurries with gases
  • high viscous fluids with gas entrainments                                             

Coriolis meters can measure the mass flow and density of any fluid, regardless if it is aerated or not.
