FLEXIM’s HPI Flow Meters-specially designed for the needs of the Hydrocarbon Processing Industry

FLEXIM’s HPI Flow Meters-specially designed for the needs of the Hydrocarbon Processing Industry


The demands of the hydrocarbon processing industry towards flow meters go far beyond those common to standard applications as the viscosity of most hydrocarbons is highly dependable on temperature and pressure, which in turn significantly affects the sonic velocity of the fluid.

Nevertheless, this also means that most hydrocarbons can easily be distinguished from one another by knowing its sonic velocity, and compensating for temperature and pressure.

The FLUXUS HPI meter combines previously independent and thus error prone measurement systems into one integral system. By measuring temperature, pressure and sonic velocity of the media flowing through a pipe, the FLUXUS HPI firmware computes the fluids density and clearly identifies the liquid by comparing the measured data with its internal library. However, the advantage of the FLUXUS HPI meter not only lies within the fluid identification and the precise measurement of standard volume and mass flow according to Industry Standard Algorithms such as TP-25, ASTM D1250 and D4311, but also in the clear detection of an Interface change, occurring when several fluids are successively passing through a pipe.

Such a sharp Interface detection is clearly indicated at terminals when tankers or barges are offloaded or when different liquid streams are allocated through a unified pipeline system and the amount of Transmix has to be kept small. 

Because of its high accuracy and repeatability, the FLUXUS HPI meters are also an ideal solution for pipeline supervision and a proper leak management. Product batches can be tracked during transportation and potential leaks can easily be revealed - helping to prevent oil spills.
