Flow, level & control E
merson has 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, with no process media pressure limitations. 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. 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 per cent 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:
FLUXUS F/G731 GP – General Purpose: Provides flexibility for various applications, and it includes disturbance correction and the Dynamic Gas Meter.
FLUXUS H731 HPI: Ideal for pipelines and terminals, provides leak detection and integrity monitoring, along with mass flow and density measurements.
PIOX S731: Focused on chemical industries for measuring mass flow, concentration and density measurements.
FLUXUS F731 WD Water Flow Meter: Designed for the water and wastewater industries, with non-intrusive temperature measurement.
FLUXUS F731 TE: Suitable for energy management and building automation, with dual-channel thermal energy measurement.
FLUXUS G731 CA: For monitoring compressed air and technical gases in life sciences and manufacturing industries.
FLUXUS G731 ST-LT/HT: Measures low and high-temperature steam for industries such as food & beverage and power generation.

ULTRASONIC FLOW METERS ENHANCE NON-INTRUSIVE MEASUREMENT ACCURACY
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.
