The non-intrusive ultrasonic gas flow meter for operation in hazardous areas

The FLUXUS G831 gas flow meter is a high performance ultrasonic clamp on meter specifically designed for measurement of dynamic flows in the process industry. This versatile and accurate gas flow meter has quicker processing capabilities and advanced diagnostics. It also includes bi-directional communication protocols, digital outputs and process inputs. Just like all other FLEXIM products, the G831 offers easy and simple installation, retrofittable design, accuracy and outstanding performance. 

With its explosion proof housing and compact design, and the corrosion resistant ATEX, IECEx Zone 1 – FM Class 1. Div. 1 rated transducers mounted in “fit for purpose” rugged mounting fixtures, the system’s mechanical stability and permanent contact with the pipe surface is assured. 

The FLUXUS G831 gas flow meter allows for bi-directional gas flow measurement of operational (gross) volumetric flowrate. The addition of intrinsically safe process inputs for pressure and temperature at the meter location means the FLUXUS G831 flow meters can now provide standard volumetric flow and mass flow. 

  • Bi-directional flow measurement – Liquids & gases 
  • High tolerance – To entrained solids & gas wetness 
  • Flexible – Configurable outputs 
  • Independent – Of pipe size, material, operating pressure & gas composition 
  • Cost effective – No pipe work,  process shut-down or maintenance-free 
  • Zero-point stable and drift free – Carefully matched & temperature compensated transducers (fully ANSI / ASME compliant) 
  • Retrofittable – No pipe modification required, no process shut-downs 
  • Maintenance-free – Free of wear & tear and abrasion, not prone to clogging or corrosion, no fugitive emissions
