The paper describe the interrogation of process vessels using acoustic signals that are generated using non-invasive mechanical impact that is generated using a solenoid driven actuator. The signals are detected using piezoelectric polyvinylidene fluoride (PVDF) sensors around the vessel. A high degree of repeatability has been demonstrated that allows observation of changes due to the contents in...
