Vibrating Wire And Multipoint Piezometers

InfrastructureGeotechnical Instrumentation

The Vibrating Wire And Multipoint Piezometers also called multilevel piezometers, provide measurements of pore-water pressure at different elevations in the same borehole. Isolation of the pore-water pressure at each elevation is achieved by the fully-grouted installation method. More info.↗
