IoT applications for Vibrating Wire (VW) gauges and sensors
Accurate diagnostics with VW gauges:
- measurement of pore water pressure or water level in boreholes/wells
- inclination changes of building structures
- expansion joints changes (eg. bridge constructions)
- landslides displacements
- tilt measurements in buildings, dams, slopes
Works with VW gauges eg. from Geotec, Gloetzl, SISGEO, RST Instruments, Geosense, Soil Instruments, ITM Soil, Systel instrumentation, Innovative Geo-technical Instrumentation, Roctest etc.
