Vibrating Wire Piezometer
The vibrating wire piezometer is a sensor designed to measure seepage water pressure or static pressure. During construction, variations in pore water pressure provide critical data for construction control; in regional stability analysis, the distribution of pore water pressure serves as an essential basis for stability calculations.
This instrument is widely used for monitoring seepage (phreatic line) and hydraulic pressure in dams, tunnels, roadbeds, slopes, and reservoir water levels. It can be permanently embedded in hydraulic structures, concrete structures, or soil masses to measure internal seepage (pore) water pressure.
The piezometer can be installed at the interface between soil and concrete, embedded in boreholes or small-diameter pipes, or mounted within piezometer pipes, boreholes, dam pipelines, and pressure vessels. With an optional built-in temperature sensor, it can simultaneously measure the temperature at the installation point.
