摘要: In this work, the geometry of near-field acoustic (NFA) sensor has been modified and adapted to media properties be characterized. The NFA method consists in studying alterations resonance curve a horn whose tip, probe, is immersed medium design changed by variation cylinders lengths their sections ratio. So sensitivity measuring liquids as well characterization cement setting increased.
