Low Battery Warning

■

The OpenWay Riva remote modules include a battery life estimator. The estimator is based

on the number of data packets sent at the various power levels and the age (self-discharge)

of the Cellular 500W module . The low battery warning allows the utility to easily identify

which water modules are nearing end-of-life in a mixed population and gives the utility the

opportunity to schedule replacement.

Note: The low battery warning is a single flag that is set when the battery has less than 10%

remaining capacity, which typically corresponds to 2 years of battery life remaining. Battery

life is evaluated daily at midnight.

For OpenWay Riva modules reporting in OpenWay Riva Network Mode.

Note: Cellular 500W module events and alarms are dependent on the module's firmware

version. For more information, see Firmware Functionality on page 13.
