Flexim FLUXUS G736 4-Beam Gas Flow Meter
The FLUXUS G736 gas flow meter combines precision digital signal processing with the well-known advantages of non-intrusive ultrasonic technology: ease of installation, retrofittable design, high accuracy, and outstanding performance. With 4 ultrasonic transducers operating in reflect mode, 8 independent ultrasonic paths traverse the gaseous medium providing superior flow averaging of up to 4 planes of the pipe section. With this configuration, the G736 flow meter averages out crossflow profile effects and achieves optimum non-intrusive flow compensation for undesirable installation locations where insufficient upstream straight pipe proximity to bends, elbows or other adjacent instrumentation creates flow disturbances.
