The vibrating wire piezometer is precisely used for:
- ShapeArray grows with your project SAAV Extend is equipped with integrated sensors designed for ease of use. Individual sensor segments are 500 mm long and can be connected to create a total length of up to 200 m.
- Simple field installation SAAV Extend’s hand-tightened threaded connectors allow users to easily add Lift Extension segments without additional tools. New extension segments are added with a simple twist, while alignment marks on the connectors maintain the azimuth of the ShapeArray.
- Complete control of the monitoring zone Users can utilize segments without integrated sensors, introduced with SAAV, together with SAAV Extend Lift Extension segments to position the entire sensorized section within the geological zone of interest.
