WATER LEVEL MEASUREMENTS -groundwater level measurement Hydrogeological steel whistle with olive passivation dimensions: length **5 mm, diameter �*4 mm weigth: **4g protective coat: high corrosion resistance layer application: measuring of aggressive water level with elevated corrosivity rate; gauge recommended for mines with saline water etc. measuring accuracy: �*0 cm Sounding devices with measuring tape A sounding device is really just a small tube, closed on one side, with a diameter of *4 mm. When the open bottom touches the liquid level at a fair speed, a “plopping” sound can be heard. In normal conditions the sound is clearly audible until a depth of **0 meters. Groundwater level measurement: The traditional approach to measuring groundwater levels is to construct a piezometer or a number of piezometers in the vicinity of the surface water feature being investigated. A piezometer is a borehole designed to measure groundwater conditions at a single point within the aquifer.
