Battery Life
Powered by four non-replaceable, long-life lithium batteries, the OpenWay Riva pit module has
an expected battery life of 20 years, dependent on use case.
Low Battery
OpenWay Riva 500W ERT modules include a low battery indicator that helps utilities proactively
plan and manage field module replacements.
Note: Low battery functionality is based on the module's firmware version. For more
information, see Firmware Functionality.
Transmission Modes
The OpenWay Riva 500W ERT pit module is an IPv6 Wisun compliant device that operates in
Mobile Mode or OpenWay Riva Network Mode.
In Mobile Mode, the module transmits every ten seconds over multiple RF channels to report on:
■
meter register value
■
cut cable or communication error events or alarm(s)
■
reverse flow (encoder version selected)
■
system leak status
■
low battery indicator
In OpenWay Riva Network Mode, the module reports four interrogation cycles daily. Each
interrogation collects six hours of interval and event data.
Note: Interval data functionality is dependent on the module's firmware version. For more
information, see Firmware Functionality.
The OpenWay Riva 500W ERT module also sends a local access beacon message every 60
seconds that allows users to gather contingency readings locally when needed.
Caution: If you perform a Switch to OpenWay Riva Network Mode or Switch to
Mobile Mode operation, it results in a loss of interval data.
The OpenWay Riva 500W ERT module operates using the 902 to 928 MHz in the ISM band
frequency band and does not require an FCC license.
