ALD® AUV inspection mode

This ALD® AUV mode has been designed to be installed into an autonomous unmanned vehicle; is a stand alone version able to record the data to be post processed after the inspection using the standard ALD® software. Data are also subject to a light processing in real time calculating a leak proabability index.


In this configuration ALD® equipment includes an acoustic sensor to be fixed to vehicle shell and a POD to be integrated in the vehicle payload. Data are acquired and recorded during the run. A partial data analysis is done in real time while the complete processing will take place after vehicle recovery.
