Sens technique

In the strict sense, a device used for measuring the pressure head at a given point in an aquifer system, which indicates the pressure at that point, by allowing the observation or recording of an unconfined water level or a pressure. The piezometer concept was extended to all man-made (wells, wells, gravel pits, etc) or natural structures (sinkholes, caves, etc) that allow access to groundwater. We then rather speak of non-operated well which allows measurement of the groundwater level at a given point of the water table. This level which varies with the groundwater exploitation provides information about the production capacity of the aquifer.
