XSENS XACT Clamp-On Liquid Flow Rate / Water Cut Meter

Clamp-on ultrasonic metering for simultaneous liquid flow rate and water-in-oil monitoring

Able Instruments are XSENS’ official UK representative for the XACT Clamp-On Liquid Flow Rate & Water Cut Meter, the first ultrasonic system to offer simultaneous net liquid flow rate and 0–100% water-in-oil measurement in a single non-intrusive unit. Designed for operators seeking highly accurate insights into multiphase flow, the XACT system uses a patented combination of multiple ultrasonic paths, including axial and dual helical pairs, to build a complete profile of the liquid inside the pipe. From this, the meter calculates volumetric flow rate, flow velocity, net oil rate, net water rate, and real-time water cut, without needing to access the process fluid.

Thanks to its true clamp-on design, XACT installs entirely outside the pipe with no spool piece, cutting, or process downtime. A typical installation takes 3–4 hours on a live line and requires no straight-run piping; the system is fully tolerant of bends, valves, and reducers. With no moving parts, no exposure to corrosive or abrasive fluids, and no risk of leaks or pressure loss, XACT provides over 20 years of service with virtually zero maintenance.

Key Features:

• 2-in-1 measurement: Simultaneous clamp-on flow rate and water-in-oil (WIO) analysis in a single device
• True non-intrusive installation: External ultrasonic sensors mount without pipe cutting, penetration, or process downtime
• Helical and axial ultrasonic paths: Patented acoustic geometry ensures accurate readings across turbulent and changing flow regimes
• High turndown capability: Flow velocities from 0.1 to 40 m/s, suitable for low and high flow applications
• No straight-run requirement: Operates accurately when mounted near bends, valves, reducers, or tees
• Maintenance-free operation: External sensor design avoids erosion, corrosion, scaling, paraffin, or fouling from process fluids
• Hazardous area certified: ATEX and IECEx approval for Zone 1 and Zone 2 installations in oil and gas environments
• Flexible pipe compatibility: Fits 2-inch to 36-inch pipelines as standard, larger available on request
• 20+ year design life: Long-term reliability with no moving parts, wear paths, or internal components
• SCADA and cloud-ready: Supports Modbus, 4–20 mA, and integration with XSENS reporting and control platforms

Built for upstream, midstream, and downstream environments, XACT is ATEX and IECEx certified for Zone 1 and Zone 2 hazardous areas and supports pipe sizes from 2” to 36” as standard. Unlike traditional intrusive flow and water cut meters, XACT works reliably across a wide viscosity and temperature range — from clean water to heavy crude or bunker oil.

For users needing fully integrated production optimisation, XACT ties into SCADA and flow control systems and can be paired with cloud-based reporting tools from XSENS. With its high turndown ratio (up to 400:1) and rapid installation, this meter is ideal for wells, separators, tanker offloading, allocation metering, FPSO skids, and brownfield upgrades.

XACT represents next-generation clamp-on metering, combining flow and fraction insights into one reliable, fast-to-deploy solution for demanding oil and gas applications.
