• Powerful leak noise spectrum analysis function
• Optional tracer gas sensor

Once the pipeline is damaged, the noise generated by the water column sprayed from the leakage point will generate two columns of sound waves that propagate to both sides. HL7000 reproduces water leakage for you, and what you hear and see is what you get from the leakage point.
1. The sprayed water column collides with the surrounding medium (soil) of the pipeline, generating noise that propagates through the soil to the ground. The HL7000 ground microphone picks up the leakage noise and displays it in graphics, audio, and spectral analysis
2. The sprayed water column generates a pressure wave inside the pipeline, which can be detected clearly by HL7000 sensors or electronic listening sticks that come into contact with valves, fire hydrants, exposed pipes, and other facilities.

HL7000 Intelligent Digital Listening Leakage InstrumentAdvantage:
The HL7000 application is easy to operate and intuitive, with all relevant menu items and measurement data clearly displayed on its high-resolution 4.3 "touch color display". The menu navigation is simple and clear.
The HL7000 host is very lightweight (600 grams) and very sturdy. The host can be worn on a belt or fixed on a sensor rod, making it easy to operate and resistant to long-term fatigue work.
The HL7000 benefits from the Bluetooth communication function of the device, which avoids interference noise from cables between devices and wind noise in the environment, ensuring that you can focus on the information of water leakage points.
The HL7000 features a unique multi-sensor design and 360 ° noise acquisition, allowing for over 10 hours of long flight operation on a single charge, ensuring accurate and reliable water leakage detection.
Bluetooth communication function, pre amplified windproof sensor can easily pick up low-frequency noise generated by plastic pipes such as PE and PVC, as well as high-frequency noise generated by metal pipes.
The HL7000 chassis design is compact and rigorous, ensuring that each unit has a fixed position, and all rechargeable devices can be intelligently charged synchronously.
HL7000 handheld sensor, compatible with electronic listening sticks and road listening functions, also has Bluetooth communication function, front amplification sensor, especially suitable for valve plug listening and uneven road listening such as grass.
Sometimes during on-site inspections, the sound of water leakage may not be obvious. HL7000 also provides a tracer gas sensor, which, thanks to its high sensitivity sensor and 360 ° data collection with the same sensitivity, automatically detects the concentration of tracer gas, quickly discovering and accurately locating the leakage point.

To ensure ease of field operation, HL7000 also provides a lightweight preamplifier sensor to ensure long-term leak detection without fatigue.

The HL7000 system integrates a GPS module that stores location, time, date, and other information. Users can transfer data to a PC computer, create work files, display trajectories and playback of water leakage noise, and print as needed.

HL7000 features:
• Audible visual leak point: graphical display
Continuous display of environmental noise and * small noise values
Long term audio storage function
• Spectrum analyzer function
Flexible filter setup with nine freely configurable filter curves
• Noise collection and storage function: 3, 15, 30 minutes

Sound intensity measurement

In addition to excellent DSA dual segment noise analysis (environmental noise and * small noise), it also displays noise spectrum information to ensure reliable leak location.

Long term monitoring

The changes in noise level can be recorded in real-time and the influence of external noise can be eliminated.

Pipeline positioning

Combined with RSP-3 vibration generator, it can be used to locate non-metallic pipelines.

precise positioning

By recording and comparing the leakage noise at different locations, the instrument automatically identifies the precise location of the leakage point, while storing GPS and audio data, which can be uploaded to a PC computer through HydroluxView software to display the stored noise and play back audio.
