The Flexim FLUXUS H831 is Zone 1 hazardous area rated flow and analytical measuring system for the hydrocarbon processing industry (HPI). This sophisticated and highly accurate non-intrusive flow meter combines very precise ultrasonic flow and sound speed measurement, advanced calculation features and diagnostics with a robust, durable and industry minded "fit for purpose" explosion/ flameproof housing. The H831’s nonintrusive flow meter 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 and D4311.
