Main Article Content

The pipeline inspection using dynamics pressure has been continuous development with the advantages on low noise, long range, accessible, and no electrical spark occurred. However, a small leak rate was a limitation of this inspection method which depend on sensor sensitivity. The scaling-square method is a mathematical based signal processing which can amplify leak signal and noise reduction at the same time. This research compared the proposing method to the conventional (with and without pre-amplifier). On the results, the advantage of scaling- square method was improved leak detection ability. Hence, the calculation on leak location of the scaling-square method present the 0.8% error for highest accuracy.
