Proprietary and Confidential
The 100W-R and 100WP-R are high-power radio frequency automatic meter reading (AMR) devices that
attach to water registers to collect consumption usage and tamper data that the ERT module transmits to a data
collection device. The ERT module operates in both bubble-up mode and two-way modes.
The 100W-R and 100WP-R ship in Factory Mode. The ERT modules acquire and transmit meter register data
within one hour following register connection. The ERT module transfers meter data immediately if the unit is
initialized with a handheld computer during installation (see
Initializing,
Connecting and Programming
the
ERT Module
on page 7).
Caution
Failure to initialize the ERT module may delay the initial reading up to 1 hour. The
100WP-R module will default to a consumption value of 0 if the ERT module is not programmed
with Itron's Field Deployment Manager (FDM).
The 100W-R and 100WP-R support 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-R and 100WP-Rs feature the following capabilities:
Leak Detection and Reverse Flow Detection
.
100W series ERT modules feature the same robust
features as Itron's 60 series water ERT modules to provide Leak Detection and Reverse Flow Detection.
For more information about Leak Detection and Reverse Flow Detection, see the Itron white paper
Detecting Leaks and Reverse Flow with 60 Series Endpoints
.
Note
The 100WP-R ERT module will not report reverse flow. Incremental encoded registers do
not provide a distinguishing signal while flowing in reverse.
Communication Error Indicators.
Last Good Read
(LGR Flag). Indicates a communication error with the register.
100W-R encoder ERT module
If this flag is set for 24 consecutive hours, it initiates a cut cable flag in the extended tampers.
The Last Good Read Flag automatically clears after the ERT module receives a successful read
from the register.
100WP-R pulser ERT module
If the Last Good Read Flag is set two consecutive times, it initiates a Cut Cable Flag in the
extended tampers.
The Last Good Read Flag automatically clears after the ERT module receives a successful read
from the register.
Note
A Last Good Read Flag may be an indicator of a damaged register.
