HL 7000-VS from SebaKMT (Germany) - Device for determining the leakage with acoustic method.
Benefits:
- A unique combination of ground microphone and active universal microphone
- All that is needed is included in the kit (control unit, ground microphone, active universal microphone)
- The highest sensitivity for determining the leakage point
How does acoustic leakage detection work?
Flowing water from a damaged water pipe causes two types of noise:
1. Water flowing out of the pipe causes the tube to vibrate. With HL 700-VS and the included microphone, you can hear the vibrations of this leak even at remote locations where you can contact the tube (valve, hydrant, connection to the building, etc.).
2. The water flowing through leakage hole produces sounds transmitted through the ground to its surface. Using the ground microphone, the HL 70-VS displays this sound volume graphically and its frequency spectrum.
The HL 7000 ground noise system provides you with a wide range of options for locating leaks thanks to the variable design and the automatic 360° sensor recording. Work assignments lasting more than 10 hours are no problem thanks to the powerful lithium-ion rechargeable batteries.
