InfrastructureDam Safety & ManagementGeotechnical Instrumentation

The Multipoint Settlement Gauges settlement systems consist of a number of hydraulic settlement gauge connected by tubing to a reference tank located on higher, stable ground. The settlement gauge is a pressure transducer with vibrating wire or capacitive technology, mounted on a plate with a protective cover. Depending on the requirement, the settlement system can be installed with just a single gauge or with multiple gauges. The typical application for the multipoint settlement systems is monitoring settlement in embankments, tunnels or other civil structures. More info.↗
