2.1 Operating principle
SePem 351 and SePem 351 HY are noise loggers for the prelim-
inary detection of leaks in water distribution networks.
The loggers measure the noises in the pipe network at set times.
The measurement data is then prepared for transfer to a receiver
(e.g. water utility).
The measurement data receiver can display and evaluate the
measurement data in its network information system.
