3. Características y tecnologías clave

The PQWT 125A incorporates several advanced technologies to ensure accurate and efficient leak identification:

• Dual-Scenario Applicability: Equipped with DMR-H40 sensor for walls and narrow spaces, and DMR-V59 sensor for indoor pipe leakage.
• Posicionamiento preciso: Features General Detection Mode for rapid area investigation and Location Mode for pinpointing leaks within 10cm.
• Dual Membrane Resonance Sensor: Utilizes a sensitive piezoelectric design to identify high-frequency leak signals from pipe cracks with high accuracy and strong anti-interference capabilities.
• AI-Enhanced Assistance Technology: Accurately reconstructs real-time acoustic fingerprints of pipeline leakage points.
• Time-Domain Waveform Dynamic Display: Separates and visualizes environmental noise from true leak signals.
• Sound-Intensity Focusing Technology: Effectively isolates and filters environmental interference for clearer signal detection.
• Multi-Dimensional Feature Extraction Technology: Distinguishes pipeline leak signals from normal water-flow acoustic patterns.
• Edge-AI Intelligent Analysis: Performs real-time leak analysis directly on the device without requiring an internet connection.
• Diseño ergonómico: Adjustable portable handle and IP54 waterproof case for versatile use.
• Batería de larga duración: 7000mAh battery provides up to 8 hours of runtime.
• Carga tipo C: Interfaz de carga cómoda y moderna.
• Pantalla LCD de alto brillo: 280 CD/M² display for clear visibility even in bright sunlight.

4. Configuración

1. Cargue el dispositivo: Connect the host machine to the charger using the provided Type-C cable. Ensure the device is fully charged before first use.
2. Conectar sensores: Depending on your detection scenario, connect either the DMR-H40 sensor (for walls/narrow spaces) or the DMR-V59 sensor (for indoor ground pipes) to the host machine.
3. Conectar auriculares: Plug the noise-reduction headphones into the designated audio jack on the host machine.
4. Encendido: Press and hold the power button on the host machine until the screen illuminates.
5. Ajustes iniciales: Follow the on-screen prompts to select your preferred language and adjust basic settings.

5. Instrucciones de funcionamiento

The PQWT 125A offers two primary detection modes for efficient leak identification.

5.1 General Detection Mode

Use this mode for rapid investigation of large areas to quickly identify potential leak zones.

1. Select "General Detection" on the main interface.
2. Move the connected sensor along the suspected pipeline path.
3. Listen for changes in sound intensity through the headphones and observe the waveform display on the screen. Higher intensity or distinct patterns indicate potential leak areas.
4. Mark areas with significant sound changes for further investigation in Location Mode.

5.2 Modo de ubicación

Once a potential leak zone is identified, switch to Location Mode for precise pinpointing.

1. Select "Location Mode" on the main interface.
2. Place the sensor directly over the marked potential leak area.
3. Slowly move the sensor in small increments, observing the numerical readings and visual indicators on the screen. The highest reading typically corresponds to the leak's exact location.
4. The device is accurate to within 10cm for precise identification.

5.3 Escenarios de aplicación

The PQWT 125A is suitable for various environments:

• Underfloor heating networks
• Household fresh-water plumbing systems
• Other pressurized pipeline scenarios (indoor walls, ground)
