| The internal state of a tube system is detected and monitored by coupling multiple inspection modules to the tube system. Each inspection module injects a signal into the tube system and detects reflections of the signals. The distance between the module and the fault causing a reflection is determined by analyzing the timing between the transmitted signal and detected reflection, along with a known propagation speed of the signals. The location of faults is determined by comparing the distance calculations from two or more inspection modules. Monitoring can be performed over time to identify the development or changes of faults. Monitoring can be done while tube system is active without disrupting the flow of material through the active tube system. | ||||||
