1. Introduzione
The PQWT-CL series pipe leak detector is a professional water leakage detecting device designed for water supply companies, heating companies, municipal construction companies, and property companies. The PQWT-CL series is primarily used to find and determine the location of leakage points in water supply pipelines. It can also be used to detect leakage in other pressure piping systems. When fluid in a pipeline erupts through a leakage source due to pressure, the noise produced by the impact on the internal wall will spread along the pipeline or through the buried layer medium to the ground. This device determines the leakage source by amplifying the leakage noise and analyzing the spectrum signal.
The PQWT-CL200 model is specifically designed for detecting leaks up to 2 meters deep.

6. Istruzioni per l'uso
The PQWT-CL200 features a user-friendly touch screen interface for selecting different operating modes.
Image: Main menu of the PQWT-CL200 device.
6.1. Selezione della modalità
From the main menu, tap on the desired mode to begin detection:
- Spectrum Analysis: Provides a real-time display of noise signals within the 1-5000 Hz range. This dual-mode functionality combines acoustic vibration with spectrum technology for precise leak detection.
- Filtering Analysis: Offers a real-time display of noise signals in the Gore band. This mode helps filter ambient noise for a clearer visual comparison of potential leak sounds.
- Registrazione dal vivo: Allows you to record and store audio data for later analysis.
- File Esploratore: Access and manage previously recorded data.
- Impostazioni: Configure various device parameters.
- Servizi: Access support or additional features.
6.2. Leakage Positioning
For precise positioning, the device utilizes spectral analysis and filtering analysis modes. In addition to listening through headphones, you can observe the visual representation of the signal strength.

- Fine Measurement Mode: Filters ambient noise and provides a columnar bar display for visual comparison of leaks and background noise.
- Point Measurement Mode: Offers multi-monitoring for detailed analysis and judgment of suspicious water leakage points. This mode displays the instantaneous value (ambient noise), minimum (leakage noise), and suspected water leak levels.
Move the sensor along the suspected pipeline path. Observe both the audio feedback through the headphones and the visual indicators on the screen. A significant increase in noise level or a distinct pattern in the spectrum analysis indicates a potential leak location.
