A tube of transparent material, open at the upper end, which makes it possible to read the static pressure of the liquid inside, obtaining safety coefficients to assess the stability of land and dams. This is the piezometer, commonly applied to optimize drainage systems in landfills or excavations.
The water level meters, also called INA (water level indicator), measure the depth of groundwater in wells, holes and holes, that is, the level of water present in the subsoil (water table).

Together, the instruments are completed for the phase of geotechnical investigations, either during a work or in the recurrent monitoring of a project, observing the pressure and seasonal fluctuations in the water level.
When automated, using an acquisition system with data loggers, data is transmitted to online data management software, using redundant modems, ensuring 24-hour monitoring.

In this way, the customer can access information online and simulate situations, generating reports and distributing subsidies to his technical team, in a simple and complete way, to be evaluated and used by those who must make decisions, all in the shortest possible time.
