Benefits
- High accuracy characteristics over the entire operating temperature range up to 0,1 % over the entire pressure measurement range, including the initial section
- High resolution
Scope
Monitoring the pressure and level of underground water under the foundations of buildings and structures, bridge supports, in the soil surrounding tunnels, under road and railway tracks, in the soil of landslide-prone areas and coastal infrastructure.
Principle of Operation
Piezometer operates based on changing the resonant frequency of vibrations of a high-quality quartz resonator with long-term stability of calibration characteristics, under the influence of ground water pressure.
