Tiltmeters are essential tools for monitoring minimal tilts and deformations in structures and the subsurface. They are used to detect early anomalies that may lead to structural damage.

Applications of tiltmeters
Tiltmeters are used in a variety of applications, including:

• Construction pits and foundations: Detecting movement during excavation work.
• Bridges and viaducts: Monitoring structural stability under load.
• Levees and embankments: Tracking of subsidence and shifts.
• Buildings and monuments: Monitoring skew and deformation.

Types of tiltmeters
Depending on the application and requirements, different types of tiltmeters are available:

• Uniaxial tiltmeters: measure tilt around one axis.
• Biaxial tiltmeters: Measure tilt around two axes, often used for monitoring complex movements.
• Triaxial tiltmeters: measure tilt around three axes, suitable for three-dimensional analysis.
• Waterproof (submersible) tiltmeters: Designed for use in wet or underwater environments.
• Tiltmeters with laser rangefinder: Provide an additional control measure by adding distance measurements to tilt measurements.

Data analysis and reporting
The collected data is analyzed and presented in clear reports and dashboards. Key end results include:

• Time series of tilt measurements: Visualization of changes over time.
• Alert systems: Automatic notifications when thresholds are exceeded.
• Integration with other monitoring data: Combining tilt data with other sensor data for a holistic view.

By deploying advanced tilt meters and associated analysis tools, potential problems can be identified and addressed early, contributing to the safety and sustainability of infrastructure and structures.
