Krohne Optimass flow meters with EGM

In an application without entrained gas present, the measuring tubes in a Coriolis mass flow meter have the desired regular oscillations. However, once entrained gas is introduced into the liquid, it dampens this regular oscillation. As the gas content increases, the measurement becomes more and more unstable and the measurement may come to a complete stop.

To overcome this, Krohne developed 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: from 0–100% gas content. Mass flow and density measurements remain stable, continuous and repeatable.

Krohne Optimass flow meters with EGM are suitable for use in two-phase flow and batch/loading/empty-full-empty applications in various food and beverage applications, such as raw milk, ice-cream, dough, syrup, tomato concentrate, spinach, meat, margarine, mayonnaise, coffee extract, coolants, sugar concentrates and molasses. Together with the indication or configurable alarm for the user, EGM can also be used to improve processes by identifying transient gas entrainments.
