The RD521 wireless noise logging
system sets a new benchmark for water
infrastructure servicing. The system relies
on any number of permanently installed
noise loggers deployed across zones
or District Metered Areas within a water
supply network. The loggers detect and
store noise generated by water leaks.
Loggers can be installed at valves,
hydrants, water meters and other fittings.
To retrieve this information, the operator
can mount the receiver to a vehicle.
The noise loggers will automatically
send saved measurements wirelessly,
where they will be recorded and
analyzed by the drive-by receiver. Using
this method, an operator can check
between 220 and 350km (140 and
220 miles) of water pipes per day.
The RD521 can retrieve information
from an unlimited number of loggers.
Each logger saves and transmits
measurements every 5 seconds for
the duration of its 10-year battery life.
This makes the RD521 the ideal
choice for managing leaks in very
large water supply networks.
