Overview
Flexim FLUXUS G831 Gas Ultrasonic Flow Meter for Hazardous Areas. The Flexim FLUXUS G831 gas flow meter is a high-performing ultrasonic clamp-on meter specifically designed for measurement of dynamic flows in the process industry. This sophisticated, versatile, and accurate gas flow meter has everything you need - faster processing capabilities, advanced diagnostics, bidirectional communication protocols, digital outputs and process inputs. The G831 offers ease of installation, retrofittable design, accuracy, and outstanding performance. ATEX, IECEx Zone 1 and FM Class I, Div.1 approved, including explosion proof housing, compact design, and the corrosion resistant transducers, the system’s mechanical stability and permanent contact with the pipe surface is assured.
Benefits
* Bi-directional flow measurement of liquids and gases
* Cost effective: No pipe work, no process shut-down, maintenance-free
* Zero-point stable and drift free - Carefully matched and 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
* High tolerance to entrained solids and gas wetness
* Independent of pipe size, material, operating pressure, and gas composition
* Flexible configurable outputs
* Advanced Meter Verification
