1, the choice of pole distance: pole distance is the distance between two electrode rods. In the same underground water detector measurement point, the greater the pole distance the greater the measured potential difference, not only faster measurement speed, and the smaller the relative error,

　　Many times will encounter home leaks and other problems, water leakage for a number of reasons, such as can be the lack of renovation caused by late hidden problems ah or waterproofing problems and so on the situation, according to the specific situation to solve the relevant problems. So how to c

　　Whether it's a new house or an old house that has been lived in for decades, a leaky sewer pipe is a real headache that not only makes the bathroom "flooded", but even makes the whole house full of odors. The best way to deal with leaking pipes is actually to carefully identify the leak point afte

　　The bathroom is the most water-intensive place in the house, if the pipes and waterproofing are not handled well, the water will seep into the walls, and in serious cases, even to the downstairs tenants' homes, affecting the downstairs decoration, but also affect the normal life downstairs.　　Bathr

　　Will be hidden in the wall or underground water pipes we call dark pipe, dark pipe design does not affect the home aesthetics and save space, can be more, but if once the leak will be a headache, the leak occurred we can not visualize the cause and location of the leak, which gives the repair poin

　　In 2016, the average leakage rate of China's urban water supply pipeline network reached more than 15.3%, and the total annual leakage of water supply pipeline network in some cities was close to 10 billion m³, which is equivalent to the annual water transfer of the South-North Water Transfer Cent

　　The use of mechanical equipment or manpower to drill holes from the surface into the ground is called well drilling. It usually refers to the drilling of exploratory boreholes and large diameter water supply wells for the exploration or development of liquid and gaseous minerals such as oil and na

　　Cities and businesses have complex workshops, facilities and dense pipelines. Water leak detection means that when a leak occurs in a water supply pipeline, the water overflowing under pressure will produce a noise that will propagate along the pipe to both sides or along the medium to the ground.

　　What are the guiding tools for drilling wells to find water?　　In the process of drilling automatic control, downhole measurement and downhole automatic control are the key link and key technology, the combination of the two is actually the automatic control technology of borehole trajectory guided

　　Ground water detector object detection water selection line is crucial, it can be said that will not choose the line will not test the water, blindly choose the line is blind to test the water.　　In the case of local rock outcrops, before measuring to do a good job of geological survey, the line of
