Data Acquisition System with Hydrophone Sensor in Pipeline Leak Detection
This paper describes in detail, a data acquisition system and the measurement results for pipeline
leak detection. The data acquisition system has a software platform to perform signal analytics; hardware for
acquiring sensor data and perform signal processing; and a hydrophone sensor for acquiring acoustic signals.
The data acquisition system was used to acquire data from packaged hydrophone sensors which were deployed
to monitor the acoustic in a water pipeline under a laboratory condition. Data analysis using both transient and
spectral interrogation methods showed that from captured data, it was possible to clearly identify water flow
disturbances due to leakages.
