Tap water leakage detection instrument working principle and determine the leakage point of the method

Tap water leakage detection instrument is a kind of instrument specialized in detecting pipeline leakage, and its working principle is mainly based on acoustic vibration principle. When there is a leak in the pipeline, the water flow will form a vortex through the leakage point, which produces a specific sound and vibration. The water leakage detection instrument receives these sound and vibration signals and amplifies them to determine the location of the leakage point.

Specifically, when the water in the pipe is under pressure, the water will flow through the leak to form eddy currents, producing a sound similar to that of a tire deflating. This sound is transmitted through the pipe to the sensor of the tap water leakage detection instrument, which converts the sound signal into an electrical signal and transmits it to the earphone after amplification through an amplifier. At the same time, the tap water leakage detection instrument also analyzes the sound signal through spectrum analysis technology, which can show the peak position of the leakage spectrum.

In order to determine the location of the leak, the localization function on the tap water leak detection instrument can be used. The localization function is usually realized by measuring the propagation time of the sound signal in the pipe. When the tap water leakage detection instrument receives the sound signal of the leakage, it will calculate the propagation time of the sound in the pipe, and calculate the location of the leakage point according to the propagation time and the length of the pipe.

It should be noted that the positioning accuracy of the tap water leakage detection instrument is affected by a variety of factors, such as the length and diameter of the pipe, the material, water quality and so on. Therefore, these factors need to be fully considered when using the tap water leakage detection instrument for detection to ensure the accuracy of the detection results.

For some longer pipes or complex pipe network systems, distributed leak detection technology can be used for detection. This technology can set up sensors at multiple points to receive sound signals from different directions, so as to more accurately determine the location of the leak.

Tap water leakage detection instrument is an efficient and accurate instrument for pipeline leakage detection. Through correct operation and use, it can quickly and accurately detect the leakage location of the pipeline, providing strong support for pipeline maintenance and repair work.
