Product Description

The Flexim FLUXUS H736 flow meter combines the highest 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 liquid medium providing superior flow averaging of up to 4 planes of the pipe section. With this configuration, the H736 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.
The H736 non-intrusive flow meter’s built-in HPI computer calculates API gravity, operational density, density at base conditions and kinematic viscosity. Volumetric flow rates reported by the meter are automatically compensated for live temperature and pressure inputs according to industry standards ASTM1250, GPA TP25, D4311 and ISO 91.
