FlexiMeasure is a lightweight inclinometer engineered for structural monitoring applications. 

Multiple segments can be connected in series to form a chain of flexibly coupled sensors. Because FlexiMeasure uses triaxial sensors it can be installed in any orientation.

The system is suitable for many monitoring applications including:

  • Tunnel distortion and convergence
  • Tunnel heave/settlement
  • Structural movement
  • Consolidation and compaction 
  • Shape/stability - profile monitoring
