HL5000Listening leak detectorProduct Introduction: :

HL5000Listening leak detectorMainly used for road listening survey and precise positioning of water leakage points. The host has a small size, light weight, and is easy to carry, The large screen display (with background light) clearly displays the measurement results and is easy to operate, making daily leak location work simple and effortless.HL5000Listening leak detectorEquipped with independent signal amplifiers and headphone amplifiers, it can minimize water leakage distortion and provide high-quality audio Sound quality can effectively detect small leaks.

How to use acoustic methods to locate leakage points?

Water leakage noise can be transmitted through the pipe wall and water, as well as through the soil near the leakage point.HL500Listening device on the ground listening through soil

Spread the leakage noise and digitize, amplify, and filter the collected sound waves,HL500modernDSATechnology automatically filters back

The background noise ensures that users receive clear and high-quality water leakage sound, accurately locating the leakage point.

useDSATechnology automatically recognizes water leakage sound and environmental noise

DSAAutomatic noise identification technology refers to the dual noise analysis technique, which automatically identifies and analyzes the measured noise intensity through continuous calculation

The background noise of the environment and the smallest noise representing the sound of water leakage are displayed simultaneously on the screen in the form of a bar graph. A wide bar chart represents' zui '

The small noise value is represented by a fine bar graph, which shows the background noise value of the environment.DSATechnology can suppress the impact of intermittent environmental interference noise on leak detection,

Highlight a continuous and stable sound of water leakage.

Audio visual leakage points in noise profile map

Beijing Jingcheng Huatai General AgentHL5000Listening leak detectorMeasurable and storable9The minimum noise value and environmental background noise value of each measurement point form a noise profile map. By comparing the double bar charts of each measurement point, the presence and accurate location of leakage points can be intuitively determined. Narrow bar chart represents environmental background noise

Intensity, the wide bar chart represents the minimum noise intensity. The noise profile function accurately measures the noise intensity at each point, avoiding the limitation of low resolution in manual listening methods. It is suitable for accurately locating leak points with a large coverage area of water leakage sound and for leak detection personnel with little listening experience to conduct road surface surveys. Forget the reading, in the bar chart measurement mode, you can listen and see the missing points, up to9Measurement storage and display, narrow section

The score represents background environmental noise, the wider part represents water leakage sound, and the higher the wider part, the closer it is to the leakage point.
