XX Series
XX Series Multiphase Flow Meter
A full-bore, non-intrusive multiphase flow meter that measures oil, gas, water and sand continuously at 96% accuracy, across the full 0 to 100% gas mass fraction range.

What it does.
One instrument in the production line. No test separator, no routing manifold, no waiting for phases to settle, no interruption to production.
The XX Series sits directly in the production line and resolves the full composition of the flow without separating it first. There is no test separator, no routing manifold, no waiting for phases to settle and no interruption to production. The meter reads continuously and reports continuously.
Because the bore is full and nothing protrudes into the flow, there is no pressure drop penalty beyond the Venturi itself, no internals to erode in sand-bearing service, and no moving parts to wear.
How the meter works
Two measurements, four answers.
A Venturi section gives total mass flow from the pressure drop across the throat. A measurement section reads the absorption spectrum across the flow to give the mass fraction of each phase. Together: four separate flow rates, updating continuously.
Scene 1 / 6
Mixed flow enters
Oil, gas, water and sand enter the meter as a single mixed stream. Nothing separates it and nothing protrudes into the flow.

Key features.
Full four-phase measurement
Oil, gas, water and solids resolved independently and continuously.
96% measurement accuracy
Across all four phases, sustained across the operating range.
Full GVF range
Valid from 0 to 100% gas mass fraction, so the same meter stays correct as the well changes.
Continuous sand detection
Solids measured as a phase, not inferred, with onset visible as it happens.
Non-intrusive and full-bore
Nothing in the flow path to erode, foul or restrict.
Self-checking measurement
Reading absorption at several energies gives more equations than unknowns, so the solver validates itself.
Annual calibration cycle
Standard industry calibration once a year rather than frequent re-verification.
Compact and integrated
Sensing, acquisition and computation in one assembly, sized for per-well skid mounting.
Specifications.
Only confirmed values are published. Further specifications are added as they are confirmed for each line size.
