About the Itron Cellular 500WModule
The Cellular 500W remote is a cellular radio frequency transmitting modules that attaches to
water registers or meters to collect consumption usage, event, and alarm data. The Cellular
500W module is an IPv4/IPV6-compliant endpoint designated to communicate over the Itron’s
OpenWay Riva multi-purpose IoT solution: OpenWay Riva Network or the legacy
ChoiceConnect Mobile platform. The Cellular 500W module transmits in Mobile Mode offering
Mobile Handheld, Hard-to-Read Mobile, High-Power Mobile, or OpenWay Riva Network Mode.
The Cellular 500W modules ship from the factory in Factory Mode, which prevents unwanted
radio transmissions during transit. After installation and programming, the pit modules acquire
and transmit meter or register data in accordance with the selected pit module parameter
settings. The Cellular 500W modules support protocols for a variety of meter manufacturer's
registers. Refer to the Water Meter and Telemetry Module Compatibility List (PUB-0063-002)
for the list of supported meters and registers.
Cellular 500W remote modules feature the following capabilities:
■
Datalogging. In OpenWay Riva Network Mode, the Cellular 500W remote module provides
3,840 buckets of interval data configurable from 1 minute to 1 hour (for example, 160 days of
hourly data or 40 days of 15 minute data).
Note: Interval data functionality is dependent on the module's firmware version. For
more information, see Firmware Functionality on page 13.
■
In Mobile Mode, the module provides 960 buckets of hourly interval data and can be set to
transmit in Mobile and Handheld Mode, Mobile High Power Mode, or Hard to Read Mode.
–
Mobile High Power Mode. The module transmits a high-powered RF message every
60 seconds. In Mobile High Power Mode, the expected battery life is 20 years.
–
Mobile and Handheld Mode. The module transmits a medium-powered RF message
every 15 seconds. In Mobile and Handheld Mode, the expected battery life is 20 years.
–
(Optional) Hard to Read Mode. The module transmits a high-powered RF message
every 30 seconds. In Hard to Read Mode, the expected battery life decreases to 15
years in this mode. The hard to read mobile mode should only be used for exceptionally
hard-to-read applications (such as meters installed in sub-basements).
■
Leak Detection and Reverse Flow Detection. Cellular 500W remote modules feature
robust algorithms that provide leak and reverse flow detection.
