What Is A Underground Water Detector

The working principle of the underground water detector is to use the earth electromagnetic field as the working field source, based on the difference of resistivity of underground rocks and ores, to measure the variation law of several (or dozens of) electric field components of different frequencies generated by the earth electromagnetic field on the ground to study the electrical changes of underground electrical sections, so as to solve the geological problems.

Application scope of underground water detector

Water search: widely used in cities, mountains and plains to search and evaluate different types of groundwater. Determine the location of the well, the amount of water dissolved in a single well, the number of aquifers and the depth of each aquifer.

The instrumental characteristics of a underground water detector

1. Fast speed and high efficiency: different from conventional electrical measurement, the measurement speed is fast, and a large number of section measurement can be completed every working day.

2, Easy to carry: this instrument USES the earth electromagnetic field as the source of the work field, does not need a bulky artificial power supply device, the whole weight of the instrument does not exceed 2 kg, very easy to carry and use.

3. Simple operation: the instrument is fully automatic controlled by microcomputer, and all measurement operations can be completed by pressing a button.

4. Strong anti-interference ability: after frequency selection and digital processing of the signal by the instrument, the abnormal curve with good repeatability can be observed even on the road with continuous traffic flow and in the work area with strong electrical interference.

5. Adopt multi-direction, multi-frequency, multi-device and multi-parameter measurement methods to obtain various abnormal maps, solve the problems of geological body position, trend, thickness and burial depth, improve the success rate of water prospecting and reduce investment risks. China Coal Group underground water detector is easy to operate 1-2 people can operate, a key into a graph, shorten a lot of measurement time.

There is no doubt that there is still a long way to go in the application of the atmospheric method, but from the current use of the effect, whether it is successful or failed, most of them can be explained clearly according to the performance of the chart, the failure is often the problem of experience, rather than the problem of instruments and methods, which more firmly our confidence in the use of atmospheric method to find water.
