What type of Accelerometers should I use? What are the things should I consider?
Hi Munshi
There is a company called Acosense that use accelerometers to detect liquid properties. They use a correlative method where the input is known and correlated to the vibration input. It takes time to build up this knowledge. You might want to talk to them - I believe that the method is patented.

Detecting pulsation inside the pipe from accelerometers does not work as well as using piezocables, see Figure 3 here.

Accelerometers do not work as well as strain gauges who in turn do not work as well as a sensor that is orthogonal to pipe wall bending.

Claes
