FLX-Rail
FLX-Rail
FLX-Rail® is a high-precision void meter designed to automatically and continuously measure maximum vertical rail deformation during every train passage.
Installed directly between the rail and the ballast, the unit is secured beneath the rail using dual magnets for fast, non-intrusive deployment.
It utilises SBV® (Start By Vibe) technology, which activates the sensor immediately before a train passes, optimising power consumption.
FLX-Rail can also be equipped with a biaxial inclinometer (MEMS technology) for static rail tilt monitoring.
Fully compatible with Senceive’s GeoWAN communication platform, FLX-Rail enables automated data sampling to understand track behaviour at critical locations and support proactive track management.

FAQs
What is FLX-Rail?
FLX-Rail is a high-precision void meter designed to automatically measure vertical rail deformation during train passages. It provides continuous, reliable data to help understand track behaviour and support proactive maintenance.
What does FLX-Rail measure?
FLX-Rail measures the maximum vertical deformation of the rail during each train passage- often referred to as “rail movement” or “rail deflection.” It can also monitor track cant and twist in both:
- Static conditions (no train present)
- Dynamic conditions (under train load)
How is FLX-Rail installed?
FLX-Rail is installed directly between the rail and the ballast and is secured beneath the rail using dual magnets. No tools, drilling, or adhesives are required, making installation fast, simple, and non-intrusive.
What is SBV® (Start By Vibe) technology?
SBV® technology activates the sensor just before a train passes. This ensures that measurements are taken at the right moment while significantly optimising power consumption.
Can FLX-Rail monitor more than vertical movement?
Yes. FLX-Rail can be equipped with a biaxial inclinometer (MEMS technology) to monitor static rail tilt, providing additional insight into track geometry.
How does FLX-Rail transmit data?
FLX-Rail is fully compatible with Senceive’s GeoWAN platform, enabling wireless data transmission. This allows for automated data collection and remote monitoring of track conditions.
What are the benefits of using FLX-Rail?
- Continuous, automated monitoring
- Improved understanding of track behaviour
- Early detection of potential issues
- Reduced need for manual inspections
- Support for safer and more efficient railway operations
Is FLX-Rail suitable for harsh railway environments?
Yes. FLX-Rail is designed for demanding railway conditions and is certified to EN 50125-3 standards for resistance to shock and vibration.
Where can FLX-Rail be used?
FLX-Rail is ideal for monitoring critical track locations where understanding rail movement and support conditions is essential, such as areas prone to voiding or track instability.
What are track voids and why are they a problem?
Track voids are gaps that form between sleepers and the supporting ballast, leaving parts of the track unsupported. When trains pass over these areas, the load creates a repeated hammering effect rather than being evenly distributed. This accelerates wear, damages track components, and can lead to geometry issues such as twist. If left unaddressed, voids can result in increased maintenance costs, operational disruption, and, in severe cases, derailment.
How does FLX-Rail help detect voids?
FLX-Rail measures the maximum vertical deformation of the rail during each train passage. Excessive or increasing rail movement is a key indicator of voiding beneath sleepers. By continuously monitoring this behaviour, FLX-Rail helps identify developing voids early before they become critical.
Where are voids most likely to occur?
- Switches and crossings
- Rail joints
- Bridge approaches
- Transition zones
