Product Description

The Flexim FLUXUS H731 is Emerson’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 non-intrusive H731 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 temperature and pressure within the meter according to industry standards ASTM1250, GPA TP25, D4311 and ISO 91, thus allowing for precise and dynamic standard volume flow measurement of liquid hydrocarbons.
