Emerson announced the Flexim FLUXUS® / PIOX® 731 series, a new range of non-intrusive, clamp-on, ultrasonic flow meters designed to offer greater flexibility, convenience and availability. The nine models in the 731 series feature high-performance volumetric and mass flow sensing technologies and a robust, functional design, providing accurate and reliable measurements for both liquids and gases.
Process manufacturers often need to make permanent or temporary flow measurements in areas where penetration into the process media would be problematic because it would typically require a production interruption, along with high costs and downtime. Although some solutions are available, not many meet the performance requirements for a wide range of demanding industrial applications.
No process media pressure limitations
To address these and other issues, the Flexim 731 series provides non-intrusive volumetric or mass flow measurements with no process media pressure limitations, ensuring cost-effective operation and low ownership costs. Modular hardware enables the reduction of assembly time by 20% for faster delivery, and integration with most up-to-date software and hardware is straightforward.
The 731 series provides disturbance correction for enhanced accuracy in challenging conditions, such as disturbed flows. It also provides the Advanced Meter Verification feature to validate meter performance, Wet Gas Correction to ensure accurate gas stream measurements, and the Dynamic Gas Meter feature for precise mass and volume correction. Various models are available to meet varying application requirements. Including a general purpose version that includes disturbance correction and the Dynamic Gas Meter, one for pipelines and terminals providing leak detection and integrity monitoring, along with mass flow and density measurements.
Meeting ATEx and IECEx standards
All models include an 84mm wide x 45mm high backlit display with 240 x128 pixel resolution for easy readability, synchronised channel averaging for precise gas measurements, and a wide power supply range of 0-240 volts AC +/-10% at 50-60 Hz or 11-32 volts DC. A USB-C port is provided as a servicing interface for programming and data extraction. Meeting ATEx (Atmosphéres Explosibles), IECEx (International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres), and EAC (Eurasian Conformity) standards, with FM (Factory Mutual) certification expected in April 2025, the Flexim 731 series is designed for global use and compliance.
