Detection of defects on Concrete using Lamb waves.

Please tell me the possiblity to success this inspection.

I am using:
Frequency 50kHz
Size of specimen 31cm
Defect types: honeycombed, water filled & air defect inside concrete about middle of the specimen.

Problem:

not consistence
Too sensitive.
Large thickness.
Higher mode due to large thickness.

Suggestion:

I need some suggestion for my master & Ph.d thesis doing this research.
please feel free to comment and give me some hope and advise for my study at university.

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
