hello friends,

i am working on one industrial project. in that project we need to detect obstacles or small particles in 8mm to 12mm diameter small flexible pipe. i implemented this technic with the help of ultra sonic sensor but ultra sonic sensor is not better solution for flexible pipe. after some research we found one solution based on Acoustic Reflectometry using microphone and small speaker like hearing machine.in this concept we need to send sound waves in hollow flexible pipe.if any particles or obstacles occurs in that pipe then echo will generate and this echo signal will detect by microphone. i need some helps to design that hardware.
If you have any other technics for detecting particles in small flexible pipes then please suggest me.
and if anyone worked on similar technology based on Acoustic Reflectometry please guide me for hardware designing.


Thank you.
