DSM Differential Settlement Monitoring system has been developed by Sisgeo for automatic and continuous long-term monitoring of differential settlement/heave of buildings, structures and embankments.
DSM system consists of a series of level sensors interconnectedby a liquid filled to a reference tank which is located on a firm point away from the area to monitor.
The measurement of fluid weigth/pressure indicates the elevation difference between the sensors and the reference tank. Sensor settlement or heave is proportional to the equivalent liquid weight/pressure change. Different models of DSM settlement sensor are produced to suit all the customer applications.
