Settlement Sensor (VW) | Model 4600(M)

  • Model 4600 Settlement System.
  • Model 4600M Settlement Sensor with hydraulic anchor (shown before and after actuation).
Model 4600(M)

The Model 4600 Settlement System is designed for the remote measurement of surface or subsurface settlement in fills, surcharges, dams, embankments, etc. A borehole is drilled which allows a pressure transducer to be anchored to solid ground below the area of settlement. A fluid filled tube extends upward connecting the transducer to a reservoir which is located in the moving strata or fill. The measurement of fluid pressure indicates the elevation difference between the sensor and the reservoir. This design eliminates the need for long liquid filled tubes. 

The Model 4600M is a special version of the Model 4600 capable of measuring subsurface zone settlement (please contact GEOKON, INCORPORATED for details).
