Network leakage is a common problem in water supply systems, which not only causes water wastage, but also puts pressure and burden on the whole system. Therefore, it is crucial to detect and repair leakage points in a timely manner. To accomplish this, we rely on a variety of principles and equipment. Next, we will introduce these methods and pipeline leak detector in detail to help you better understand the various aspects of net leak detection.
1. Sound Detection Method
A noisy pipeline leak detector or listening stick is used to capture sound changes in the pipeline to determine the location of the leak. This is usually done at night or early in the morning to minimize interference from background noise.
2. Pressure change method
By monitoring pressure changes in the pipeline, the pressure sensor is used to quickly and accurately locate the leakage point.
3. Flow measurement method
Using flow meters and flow sensors to monitor the flow changes in the pipeline network, to determine whether there is a leakage and the location of the leakage.
4. Leakage detection method
The use of soil moisture sensors to monitor the changes in soil moisture around the underground pipeline to determine whether there is a leakage.
5. Thermal imaging method
Use infrared thermal imaging camera or thermal imaging camera to detect the temperature change on the surface of the pipeline and find the possible leakage point. The effect is better at night or early in the morning.
6. Chemical tracer method
By injecting fluorescent dyes or chemicals into the pipe network, the location of the leakage point is determined through sampling and analysis.
7. Non-destructive testing technology
Non-destructive techniques such as ultrasonic testing, magnetic fluid testing and radar testing are utilized to accurately detect pipeline leakage.
With the continuous progress of technology, more advanced principles and equipment will be applied to the field of network leakage detection in the future to further improve the accuracy and efficiency of detection. Choosing the right methods and tools is essential to ensure the normal operation of the water supply system and reduce the waste of water resources.
