Measurement Method
The sensing device consists of a piezoelectric element and a signal amplifier. The piezoelectric element acts as transducers that generates and transmit different Levels of voltage based on the acoustic leak in water pipeline.The amplifier boosts the acoustic signal so that it can be measured. The whole unit includes piezoelectric element and amplifier housed in a robust IP68 proof enclosure.
