Entrained Gas Management EGM technology is now available for all KROHNE OPTIMASS Coriolis mass flowmeters. With the latest additions OPTIMASS 3400 and OPTIMASS 7400, now the whole OPTIMASS series offers continuous and repeatable mass flow or density measurement with 2-phase flows such as liquids mixed with gas, slurries with gases or highly viscous fluids with gas entrainments.
In the past, this presented a huge challenge for mass flowmeters: without gas entrainments, the measuring tubes in the Coriolis mass flowmeter have the desired regular oscillation. Gas entrained in the liquid dampens this regular oscillation, and as the gas content increases, it can come to a complete stop. To overcome this, KROHNE developed powerful control algorithms that allow the meter to maintain oscillation and continue to measure even with complex flow conditions. This is possible even during a complete transition from a pure liquid phase to a gas phase and back, i.e. from 0…100% gas content. Mass flow and density measurements remain stable, continuous and repeatable.
Together with the indication or configurable alarm for the user, EGM can also be used to improve processes by identifying transient gas entrainments.
