DSM System

The DSM Differential Settlement Monitoring System has been developed by Sisgeo for automatic and continuous long-term monitoring of differential settlements or heaves of buildings and structures.
The DSM structure system consists of a series of DSM tank-gauges interconnected by a small hydraulic tube to a reference tank, which is located on a firm point away from the area that is going to be monitored.

The hydraulic tube is filled by a de-aired mixture of 50% glycerine (99%) and 50% water. This mix is usually supplied by Sisgeo and is chemically inert to all components in the system.
The measurement of fluid level inside each DSM tank indicates the elevation difference between the sensors and the reference tank.

Technical specifications

DSM systems are very sensitive to temperature changes. Accurate measurements require that temperatures be monitored at sensor locations. Data is processed utilizing “Fieldstat” software..
