WATER LEVEL INDICATORS

    applications > water level surveys in wells/piezometers/tanks, temperature and conductivity, downhole indicator

Always one of the flagships of PASI, water level testing devices are piezometric level meters for liquids (usually water), intended for quick measurements in wells and tanks by a single operator who can easily operate on the surface. This portable instrument, easy-to-use and to maintain, is ideal for monitoring changes in groundwater level within piezometers. They are often used as a first control downstream of dams, in the areas surrounding landfills and in areas where there is strong groundwater extraction.
Measurements are carried out using a probe. The flexible probe has a min. diameter of only 10mm. It is indispensable for monitoring wells and checking for possible contamination within groundwater at different depths when crossed by the same catchment work. In addition, it can also be useful to measure the temperature variations of the water inside a well. Similarly, in alluvial soils, it will be important to periodically check the bottom level in order to verify the silting of the well itself, at the base of which thin sediments not retained by the filtering column can accumulate.
