[quote author=Sumit link=topic=27.msg37#msg37 date=1209982334] WILL IT BE POSSIBLE FOR A ACOUSTIC SAND DETECTOR TO DETECT SAND WITH WATER ? HOW ?
BEST REGARDS, SUMIT RAMA
Yes it is possible. Sand is a high density material (definitely dense than most if not all liquids), therefore an acoustic signal wave going throough it should be able to register quite well.
