Settlement Sensor VW Model 4600 M

Settlement Sensor VW Model 4600 M

The Model 4600 Settlement System is designed for the remote measurement of surface or subsurface settlement in fills,

Description

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.
