SoundSens i is a synchronised multi-sensor correlator. It records leak noise and its precise location.
A deferred programming function enables the instruments to be left to record during the night, which is a very favourable period as there is little interference noise.
The correlator has a one-week data storage capacity (650,000 values), which allows very flexible utilisation. The data is recovered through an infra-red link with the reading PC. Sampling frequency is configurable between 1 and 5.5 kHz.
