Flexim FLUXUS H831 Hydrocarbon Meter for Standard Volume Flow in Hazardous Areas
Product Description
The Flexim FLUXUS H831 is the ATEX/IECEx Zone 1 and FM C1D1 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 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.

Features
Fit for purpose: process inputs (pressure and temperature) enabled for hydrocarbon processing applications and standard flow reporting according to industry standards ASTM1250, GPA TP25, D4311 and ISO 91.
Highly cost-effective: no pipe work, no process shut-down, virtually maintenance-free.
Matched, paired and wet calibrated flow transducers (traceable certification to national standards).
Excellent zero-point stability and drift-free.
Wide turndown ratio.
Independent of pipe size, material, operating pressure, medium and temperature (from as low as -200 to +630 °C / -328 to +1166 °F).
Free of wear and tear and abrasion.
Not prone to clogging or corrosion.
No pressure loss or risk of potential leaks and fugitive emissions.
Advanced Meter Verification.
