During what time is it recommended to use a correlator for leak detection?

Using a correlator for leak detection is most effective at night due to reduced outside noise. During nighttime, ambient sounds that could interfere with the detection process are significantly lower. This allows the equipment to better distinguish between the sounds of water leaks and other environmental noises, leading to more accurate and reliable results.

During the day, the noise from traffic, machinery, and general human activity can create a challenging environment for leak detection, as these sounds can mask the subtle noises associated with leaks. Therefore, conducting leak detection at night enhances the correlator's ability to pinpoint the location of leaks more precisely.
