The electric water level gauge is used for rapid and reliable measurement of water levels in wells, observation tubes and narrow boreholes.The measuring value can directly be read on the measuring cable. Fast changing in water levels (pumping test) can be measured continuously.
If the sensor tip (zero point) is touching the water surface the signal lamp and an accoustic signal at the cable drum will switch on. Faulty measurements are not possible as the contact can only be made by touching the water surface. By slightly raising and lowering the cable the signal goes off and on again, so the exact water level can be determined. The measuring depth can directly be read on the cable in m and cm.
