XSENS XRATE & XACT LIQUID
Clamp-On Flow & Fraction Meter
The XSENS XRATE & XACT LIQUID series represent a breakthrough in clamp-on ultrasonic metering, providing both flow rate and fluid fraction measurement from outside the pipe. Using patented helical and axial ultrasonic transmission, these meters achieve in-line accuracy levels while retaining the benefits of non-intrusive installation: no pipe cutting, no pressure drop, no moving parts.
Developed in partnership with Christian Michelsen Research (CMR), this disruptive technology delivers accurate, cost-effective, and safe flow measurement solutions for liquids and gases in challenging industrial applications.
- Dual measurement: flow rate + fluid fraction (0–100%)
- Helical + axial ultrasonic transmission for tomographic flow profiling
- Accuracy comparable to in-line multipath meters
- Non-invasive clamp-on design: no pipe penetration or leak risk
- Installed cost up to 50% lower than conventional in-line meters
- No pressure drop, clogging points, or moving parts
- Maintenance-free operation with 20-year transducer life
- Safe, HSE-compliant installation on pressurized pipes
