How Does The Underground Water Leak Detector Work

The geophysical instrument uses the physical properties of groundwater, such as the benign conductivity, intensification effect, and radioactivity, to find information about the location, depth, water level, and water output of the groundwater. The underground water detector is also commonly known as "water finding instrument" and "water measuring instrument".

How dose the underground water detector work?

The principle of the geophysical prospecting (underground water detector) instrument is based on the natural electric field as the field source, based on the electrical differences between the underground rocks and ore (groundwater), and measuring the changes in the electromagnetic fields of different frequencies in the natural earth electromagnetic field to study the electric field and An anomaly produced by different geological bodies is an electrical exploration instrument to solve geological problems.

At present, there are two types of domestic geophysical underground water detectors in China. One is the nuclear magnetic resonance underground water detector, which is relatively expensive. The other is a commonly used natural electric field water detector. The price is close to the people. It is a helper for well users to solve dry eyes for everyone. A common device in question. This is usually the well-drilling water analyzer. The underground structure analyzed by the instrument itself can not see the amount of water in the variable layer fracture zone. The underground structure is used to analyze the water-containing conditions. The place has the best water-containing conditions. Combined with personal geological experience and local lithological consent analysis, the amount of water can be determined.

The theoretical basis and design principles of the natural electric field geophysical instrument are described, and the frequency selection of the earth electric field audio electric field signals at multiple frequency points is designed based on the electromagnetic field theory to qualitatively understand the observation scheme of the typical structure of the underground geological body. Weak signal detection technology is used in the design to amplify, filter, frequency-selective detection, integration, and signal conditioning to convert the weak audio geoelectric field signals into digital signals for analysis.

The instrument can observe electric field signals of multiple frequencies, and utilizes a variety of reliable technologies in hardware design and software development to enhance the ability to resist interference and the stability of the system. The instrument adopts multi-channel and multi-mode data acquisition, and performs automatic analysis and processing on the collected data, saves the data in real time and draws a graph, and finds the broken zone through the graph.

Through the comparative analysis of field work examples, the natural electric field frequency selective instrument can reflect the geological information in a certain depth range underground, which can be used for rapid general survey of geological minerals, engineering geophysical prospecting and water resources.
