KROHNE has highlighted recent developments in its Coriolis flowmeter technology, addressing process measurement challenges in applications requiring high accuracy, stability, and operational flexibility. The technology is intended for industries such as chemical processing, food and beverage production, and oil and gas, where precise mass flow measurement is critical for process control and custody-related operations.
Measurement accuracy and functional scope
KROHNE’s Coriolis flowmeters achieve mass flow measurement accuracy of approximately 0.1%, significantly exceeding the performance of many alternative flow measurement technologies. In addition to mass flow, the instruments simultaneously measure density and temperature, enabling comprehensive process monitoring with a single device.
Because Coriolis measurement is independent of flow profile, the meters can be installed in any orientation without requiring straight pipe runs upstream or downstream. This simplifies integration in existing plants and reduces installation constraints in space-limited environments.
Single straight tube design
A defining characteristic of KROHNE’s Coriolis portfolio is its single straight tube measuring principle. Unlike traditional bent tube designs, the straight tube configuration reduces pressure drop and supports easier cleaning and maintenance. This geometry is particularly suited to applications involving shear-sensitive fluids or processes where minimizing product stress is essential.
The straight tube approach also improves mechanical robustness and supports stable measurement under varying process conditions, contributing to long-term repeatability.
Entrained Gas Management capability
One of the key technical differentiators is KROHNE’s Entrained Gas Management (EGM) functionality. Two-phase flow conditions, where gas is present in a liquid stream, typically disrupt Coriolis measurement and can cause many meters to stop operating. EGM allows the flowmeter to continue functioning during entrained gas events, maintaining repeatable measurement without interrupting the process.
While accuracy may temporarily deviate from nominal specifications during such conditions, the ability to sustain operation improves process continuity and reduces downtime in applications where gas ingress cannot be fully avoided.
Application range and industrial relevance
KROHNE’s Coriolis flowmeters are used in mass-based production processes such as batching, blending, and recipe control, as well as in applications involving product transfer and ownership change. The product range includes compact designs for confined installations and larger meters for high-flow industrial systems.
By combining high measurement accuracy, installation flexibility, and resilience to challenging flow conditions, KROHNE’s Coriolis flowmeter technology supports reliable process measurement across a wide range of industrial environments.
