ABB Flow-X flow computer

Accurate measurement is crucial to custody transfer. Minor errors can potentially create high financial impact, but precision can be hard to maintain when operating in harsh field conditions. The ABB Flow-X gas and liquid flow computer has been improved to meet the Class 1 Division 2 and ATEX/IECEx Zone 2 certification, which extends operating temperature range from -40 to +75°C and 5% to 95% humidity.

Its analog inputs provide an accuracy of 0.008% and make the Flow-X series a high-accuracy flow computer for hazardous areas that complies with the stringent standards for custody transfer and legal metrology for the control room and the field.

Flow-X is also a useful automation platform used for measurement and control of gas and liquid pipelines, LACT units and truck and rail loading and offloading systems. Its complete control functionality eliminates the need for any programming, an additional PLC or a sampler controller. Besides the typical proving, batching and PID control functions, Flow-X also provides configurable valve, sampler, LACT and liquid (un)loading control. It doesn’t require additional purging, Ex enclosures or junction boxes.

Rigorously tested for immunity for radiated and conducted electromechanical disturbances, it also incorporates role-based access control and secure communication to prevent unauthorised access and data tampering.

A multilingual user interface provides a guided set-up and configuration of the flow metering system. Its traceability is fully compliant with API MPMS Chapters 21.1 and 21.2, including as-found/as-left verifications.
