OKM Waterfinder - Water Detection Equipment

OKM Waterfinder - Water Detection Equipment

Geoelectric methods are used to explore groundwater resources. These methods are also applied in engineering geology and archeological investigations for the detection of caves, voids, caverns, fractured zones and metallic objects.

Control unit of the water detector with connected

The rectangular area defined by the 4 electrodes is scanned for possible water deposits.

The Waterfinder (water locator) is mostly used in dry areas and most wanted in countries with water deficiency to search for ground water or new water resources. This measuring instrument is capable to locate new water sources in various ground conditions. The water detector is most effective in sandy soils, desert areas, rocky grounds and in mountain areas.

The Waterfinder is based on a geoelectric measuring method, to locate water deposits in the ground. The geoelectrical measuring method is used to measure the ground resistivity and the different electrical conductivity of water deposits. So the water locator can recognize small variations in the underground structure of the measured area and can detect anomalies from the sourrounding soil. Such anomalies can be water deposits, ground water, humid places or accumulation of water in certain underground strata.

The usage of the Waterfinder is practicable and very easy. There are 4 electrodes, which should be sticked into the ground to obtain a rectangular measuring area. The maximum size of the measured area can be up to approx. 800 square meters. These electrodes should than be connected to the main unit of the water locator in the middle of the field.

After powering on, the water locator will start automatically to measure the ground resistance between each electrode in a specific manner. The whole square area will be scanned and the procedure is full automatically. After a few seconds of scanning the measured result will be visible on the display of the water locator. After a short calculating time the device will indicate in percentage how much water exists in the measured area. This procedure can be repeated as much as wanted until a possible water source has been located.
