Flexim Fluxus/Piox 731 nine-model series modular, clamp-on, ultrasonic flowmeters provide versatile, non-intrusive and precise volumetric and mass flow measurement of gases and liquids with no process media limitations. The 731 series provides disturbance correction for enhanced accuracy in challenging conditions, such as disturbed flows. They also feature Advanced Meter Verification to validate meter performance, Wet Gas Correction to ensure accurate gas stream measurements, and Dynamic Gas Metering for precise mass and volume correction.
Various models are available to meet varying application requirements, including:
- Fluxus F/G731 general purpose (GP)v provides flexibility for various applications, and includes disturbance correction and Dynamic Gas Metering.
- Fluxus H731 HPI is ideal for pipelines and terminals, provides leak detection and integrity monitoring, and mass flow and density measurements.
- Piox S731 focuses on chemical processes for measuring mass flow, concentration and density measurements.
- Fluxus F731 WD water flowmeter is designed for water/wastewater applications, and has non-intrusive temperature measurement.
- Fluxus F731 TE is suitable for energy management and building automation, with dual-channel thermal energy measurement.
- Fluxus G731 CA monitors compressed air and technical gases in life sciences and manufacturing processes.
- Fluxus G731 ST-LT/HT measures low- and high-temperature steam for food and beverage and power-generation applications.
All models include an 84 mm wide x 45 mm high backlit display with 240 x 128 pixel resolution for easy readability, synchronized channel averaging for precise gas measurements, and a wide power supply range of 0-240 VAC ±10% at 50-60 Hz or 11-32 VDC. A USB-C port is provided as a servicing interface for programming and data extraction.
The 731 series complies with multiple international standards, including Atmosphéres Explosibles (ATEx), International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres (IECEx) and Eurasian Conformity (EAC) standards, with Factory Mutual (FM) certification expected in April 2025.
