TDC-0909-000 100W Datalogging Endpoint Installation Guide 3
Proprietary and Confidential
The 100W datalogging endpoint is a high-power radio frequency automatic meter reading
(AMR) device that attaches to a water meter to collect consumption usage and tamper data
that it transmits to a data collection device. The endpoint operates in both bubble-up mode
and two-way modes.
The 100W ships in Factory Mode. The endpoint will acquire and transmit meter register
data within one hour following register connection. The endpoint will transfer meter data
immediately if the unit is initialized with a handheld computer during installation (see To
initialize the 100W on page 5).
Caution Failure to initialize the endpoint may delay the initial reading up to 1
hour.
The 100W supports protocols for a variety of meter manufacturer's registers. Refer to the
Water Meter Compatibility List (PUB-0063-002), for the list of supported meters and
registers.
100W s feature the following capabilities:
Leak Detection: The 100W indicates (by meter reading software) that a potential
system leak exists if a zero consumption value does not occur over a programmed
period of hourly register reads. Upon detecting a zero consumption, the leak test
period is reset. The optional Itron Leak Sensor provides advanced leak monitoring
through data collections analyzed using a unique mlogonline™ portal.
Tamper Indicators: To minimize the possibility of theft, the 100W features cut cable
tamper reporting as well as a security seal to indicate physical tampering. Either a cut
cable or a register/endpoint communication error will set a cable tamper flag. This flag
will remain set for one day after communication is restored when the endpoint is
programmed to Network mode, or 40 days after communication is restored when the
endpoint is programmed to Mobile mode.
Reverse Flow Detection: To detect reverse flow, the 100W compares the register’s
current consumption reading to the reading obtained at the previous hourly update. If
the register value is less, the endpoint signals the meter reading software to report a
reverse flow condition for the next 40 days. The 40 day time limit is continually reset
if another reverse flow event occurs before the period has timed out.
Battery Life
Powered by two non-replaceable, long-life lithium batteries, the 100W has an expected
battery life of 20 years when the endpoint operates in default Mobile or Fixed Network
Operating mode.
