BASIS PRINCIPLE OF ACOUSTIC CONTROL

Leakages Detection with the Acoustic Method

The acoustic method principle is to identify leakages signals through ultra-sounds emitted nearby the valve shut-off WITHOUT ANY LOSS OF PRODUCTION.

Acoustic Control Method
Leakage Noise

Ultra-sonic signals could come from a lot of points:

Many factors will influence the spreading and the attenuation of the leakage signal, so the amplitude and the spectral distribution in the parts and the pipes:

To determine leak severity, MMC uses a digital analyzer with these technical specifications:
