ZCorr Digital Correlating Loggers (DCLs) pinpoint the exact locations of any leaks in one overnight survey. The easy-to-use ZCorr software provides the ease and accuracy of pipeline leak detection and pinpointing.

Put 8 ZCorr Correlating Loggers out in the afternoon and do an 'Overnight Survey'for water leak sounds at valves for hours late at night. Water main leak clearly apparent? Do a 'Short-term Recording' to Pinpoint it with just 2 or 3 ZCorr Correlating loggers on valves, hydrants, or meters nearby.

  • Performs correlations exactly like a correlator
    – Pinpoints exact distance to leak
  • Can operate at night in 'Overnight Survey'
    – Less traffic and usage noise
  • Multiple loggers survey large areas for leaks
    – 8, 16, or 32 loggers over miles of pipe
  • Can turn 'ON' multiple times with hours between recordings
    – Best chance to get leak sounds without usage noises
  • Can find smaller leaks at night
    – less traffic and usage noise
  • Even more sensitive than human ear
  • User can listen to the actual leak sounds for 60 seconds for each  recording (unfiltered)

  • Accurate registration and pinpointing of each leak sound occurs automatically with every recording
  • Tracks the patterns of the leak sound over time to 'tune in' to the true leak sound signal
  • Digital signal processing isolates (multiple) leak sounds individually at each logger, statistically optimizing their correlation at each possible value of time delay
  • No fixed high or low filters are needed for matching the audio frequencies at two correlating loggers
  • Can extract the true leak sounds from each recording even when louder noises are present at the same audio frequencies

  • Multiple Loggers Can Survey Large Areas For Leaks (8, 16, or 32 loggers over miles of pipe)
  • Can Turn ON Multiple Times With Hours. Between Recordings (best chance to get leak sounds without usage noises)
  • Can Find Smaller Leaks At Night (less traffic and usage noise)
  • Even more sensitive than human ear
  • User can listen to the actual leak sounds for 60 seconds for each recording (unfiltered)

Problem:

The downtown area of Sausalito, California is very busy with foot traffic, automobiles, restaurants, shops, and hotels from 6 AM until after midnight every day. Leak surveying and leak pinpointing for Marin Municipal Water District are almost impossible during these times.

Solution:

Use ZCorr Digital Correlating Loggers to do an “overnight survey and pinpointing” on the main valves and hydrant valves along Bridgeway Avenue to detect any leaks.

Result:

ZCorr found a small leak (cut in top of pipe?) that was totally unknown on Broadway close to Princess Street.
