Invensys flow measurement technology earns two new patents

Invensys has received two additional patents for the core technology of its Foxboro CFT50 digital Coriolis mass flowmeter.


Invensys has received two additional patents for the core technology of its Foxboro CFT50 digital Coriolis mass flowmeter. Patents 6,754,594 and 6,758,102 apply to the flowmeter and its ability to correct for two-phase flow— specifically to accurately measure traditionally difficult-to-handle materials and gas/liquid flow. Two-phase flow is a major contributor to process interruptions, measurement inaccuracies, and deviations in product quality.

The patents relate to new signal processing techniques used to measure mass flow and density, and for the operational aspects of keeping a Coriolis meter running stably in single- or two-phase flow conditions (and dynamic transitions between these flow conditions). The first includes an advanced control and measurement system with high-speed digital signal processing that responds to changing flow conditions significantly faster than standard Coriolis flowmeters. The second relates to detecting and compensating for two-phase flow conditions and generating a validated mass flow measurement. (Traditional Coriolis flowmeters typically stall or give inaccurate measurements in two-phase flow situations.)

These technologies were developed through a collaborative program between the Foxboro Measurements and Instruments Div. of Invensys Process Systems and Oxford University in the UK. They were incorporated into the Model CFT50 device in 2002.
