Hydrophone Kit
For SeCorr 300
Leak Noise Correlator

Most leak correlators use microphone type sensors to pick up leak sound traveling down the wall of the pipe or tubing. Sound does not travel the same speed or distance on different materials. Sound on Plastic pipe travels only around 200' limiting the usefulness of most leak correlators in plastic pipe systems. The HYDROPHONES  are designed to listen for the leak sound in the water column rather than the pipe wall. Sound travels many times faster in water than on metal or plastic, so hydrophones can increase the performance on plastic pipe greatly. On the analog correlators SeCorr 300, the correlation distance can be extended up to 1000' or more plastic pipe with the SeCorr 300. Hydrophones are connected to hydrant hose nozzles to correlate for leaks between them. The hydrants do need to be flushed and pressurized with water to correlate.
