Product Description

The Flexim FLUXUS H721 is Flexim’s flow and analytical measuring system for the hydrocarbon processing industry (HPI). This sophisticated and highly accurate non-intrusive flow meter combines precise ultrasonic flow and sound speed measurement with advanced calculation features and diagnostics. The H721’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 temperature and pressure within the meter according to industry standards ASTM1250, GPA TP25 and D4311 thus allowing for precise and dynamic standard volume flow measurement of liquid hydrocarbons.
