The underground water pipe network is an important part of the urban water supply system, however, due to many reasons such as aging, corrosion, geological changes, etc., underground water pipes may leak. This not only causes waste of water resources, but also affects the safety of water supply and the normal operation of public facilities. Therefore, timely detection and repair of underground water mains leakage is crucial. This article will introduce several common underground water pipe leakage detectors and their working principles.
1. Sound detector
Sound detector is a kind of passive monitoring equipment, which is placed near the underground pipe and detects water leakage by capturing the sound of water leakage inside the water pipe. The sound of a leak generates specific sound frequencies that can be analyzed and identified by the instrument. The sound detector is non-invasive and can be monitored without affecting the normal water supply, greatly improving the monitoring efficiency.
2. Groundwater Dynamic Monitor
Groundwater dynamic monitor is an advanced instrument that monitors parameters such as pressure, flow and temperature inside the pipe in real time through sensors installed inside the pipe. Once there is a water leakage, these parameters will change and the monitor will immediately capture these changes and issue an alarm. At the same time, through data analysis, it can also assess the extent and location of the leakage, providing precise information for emergency personnel.
3. Infrared Thermal Imager
Infrared thermal imager is an instrument that uses infrared rays to detect the surface temperature of an object. In underground water pipe leakage detection, it can detect the temperature change of the soil around the pipe. Once there is a leak, the water flow will take away the heat and cause the temperature of the surrounding soil to drop. An infrared thermal imager can capture these temperature changes and display them in an image, thus helping inspectors pinpoint the leak.
Each of the above three underground water pipe leakage detectors has its own advantages, and you can choose the right one to detect according to the actual situation. Regardless of which method is used, timely detection and repair of leaks is of great significance to safeguard water supply, conserve water resources and protect the normal operation of public facilities.
