Pipe leaks are a common problem in homes and commercial establishments, and in order to solve this problem, it is crucial to understand and use the proper pipe leak detection equipment. In this article, we will introduce some of the commonly used pipe leak detection equipment and how they are used.
I. Mechanical Listening Method
Mechanical listening method is the most basic pipe leakage detection method. Users holding a mechanical listening pole along the pipeline to listen to the sound of water leakage, focusing on the pipeline exposure points, such as valves or hydrants at the abnormal sound. Although this method requires some experience, but it can help you determine the general location of the leak.
Second, electronic listening method
Electronic listening method in the mechanical listening rod on the basis of the increase in electronic amplification of the signal, so that the sound of water leakage is clearer. Users holding electronic listening rod, along the pipeline to listen to the sound of water leakage one by one, the same need to pay attention to the sound of the pipeline at the point of exposure. This method is more accurate than the mechanical listening method, but still need some experience.
Third, spectrum analysis
Spectrum analysis method using the principle of sound vibration, the sensor will leakage sound signal acquisition, through the host processing, to visualize the spectrum and the way the signal column is displayed on the host screen. This method can more accurately determine the location of water leakage, is currently a more common method of leakage detection. Recommended model: PQWT-L series pipeline leak detector.
Tracer gas detection method
Tracer gas detection method in the acoustic vibration, spectrum analysis method based on the addition of tracer gas detection and pipe search function. Tracer gas detection function is to inject hydrogen and nitrogen mixed tracer gas into the pipeline, and analyze the hydrogen leakage of the suspected water leakage point on the ground to verify and locate the water leakage point. Pipe searching function is to apply specific acoustic signals to the pipeline that has been emptied of water, and search for the acoustic signals on the ground to realize pipe searching and positioning. Recommended model: PQWT-BT series wireless pipeline leak detector.
V. Digital Module Automatic Analysis Method
The digital module automatic analysis method uses multiple probes to collect water leakage signals and wirelessly transmit them to the host, which automatically calculates and analyzes the suspected water leakage points according to the water leakage signals collected by each probe through the digital signal processing chip and digital filtering chip. Recommended model: PQWT-CL900 pipeline leakage detector.
Neural network calculation method
Neural network calculation method adopts B-P neural network calculation method technology, equipped with 5-20 wireless monitoring sensors distributed collection of possible leakage signals in the region, through the signal repeater wireless transmission to the central controller for big data comparison, to achieve efficient and rapid analysis, automatic judgment and automatic screening leakage points. At the same time, it can also record in real time, and the collected data can be exported and saved, which is convenient for the production of leakage detection report. The biggest advantages of this equipment are: fast inspection, no need for pipeline, strong anti-interference, no need for leakage testing experience. Recommended model: PQWT-LDC-20M Pipe Leakage Detection Trolley.
Summary: Understanding and using the proper pipeline leak detection equipment can quickly and accurately determine the location of the leak and solve the leak problem. Different devices have different advantages and disadvantages, and choosing the right one for your situation is crucial. Also, using these devices properly is the key to success. If you have questions about how to use these devices, it is recommended to refer to the device manual or seek professional help.
