The sensor engages in the monitoring well, the logger can be placed in the well, or outside it. The logger transmits the measured data with a configurable interval to ElliTrack.nl.
The ElliTrack-W using an acoustic pulse to determine the distance between the measuring head and the groundwater. At the measuring head is fixed a measuring tube. The measuring tube must at all times stabbing in the groundwater. The minimum measuring approx 35 cm, the maximum measuring approx 4 meters. Thus, can therefore be a variation in the ground water level of about 3.65 meters can be measured.
