5.3. Power
supply
The RSE meter can be powered exclusively by batteries.
The metrological battery is dimensioned to assure the operation of RSE for at least 15 years. The battery autonomy was estimated in
the following reference operating conditions:
The 169 MHz radio transmission battery is dimensioned to assure the operation of RSE for at least 15 years. The battery autonomy was
estimated in the following reference operating conditions:
169 MHz Radio Communication:
Tx Only radio cycle
–
Short Message (volume reading) transmitted - 5 messages/day
Tx-Rx radio cycle
–
Tx-Rx talks with long message
Display message/ZVEI communication
5 minutes per month
Valve control:
1 complete control (including 1 opening and 1 closing) every year
1 valve test period (valve periodic test) 1 cycle per month
Ambient temperature profile:
5% of the time at -25

RSE implements and manages service quality logs, available only through the communication channels (not on the display) able to
verify the deviation of the actual operating conditions from the reference ones.
5.3.1. Connecting the batteries
RSE is supplied with the metrological battery already connected and inserted in the related compartment; therefore, RSE is ready for
operation.
5.3.2. Supply status
Power status shows the current battery level.
The functionality of calculation of the actual use of the battery has been implemented in order to signal when the limit of 90% is reached.
A weight has been configured for the main activities of the device (periodic and not). Therefore the actual consumption of the battery is
calculated according to the time elapsed, the individual functions actually performed and the weight in terms of consumption. When this
estimate exceeds 90% of the value set as threshold, the appropriate alarm event is generated.
