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.
