Aquarius offers the best leak detection technology
|Parameters||Aquarius Spectrum – Correlating Sensors||Noise Loggers|
|Technology||Requires time synchronization of all the sensors
Requires transmitting the vibration recording for analysis on the server
|Very simple technology|
|High Quality Sample||Automatically records and sends 20 seconds of wave file to the server for analysis. The sound file can be downloaded and listened to.||Requires a few seconds of compressed data – the outcome is mostly one number (the level of noise).|
|Detection Method||Multi Spectral Correlation (Low false positive rate):
– 3-15 correlations are needed before alerting.
– Capable of detecting small leaks (below background noise).
|Detection by Noise (High false positive rate):
– Only one noise sample is needed before alerting.
– Capable of detecting only high noises which are above the background noise.
|Spacing||Large distance between sensors (1,000 ft / 330 m)||Shorter distance between loggers (500 ft /150 m )|
|Leak Location||Up to 10 ft / 3 m deviation||Provides a wide radius that requires a field team with mobile correlators for pinpointing|
|Installation||Multiple choices: Aboveground and belowground||Only one method|
|Material||No limitation||Does not support PE pipes, limited range with PVC pipes|
|Diameter||No limitation (ACC up to 24” and hydrophones above 24”)||Up to 12” pipes|
|Size of Leak||Good estimation. Supports 0.5 mm leaks||No estimation|
|Integration with Mobile sensors||Seamless integration||No integration|
