8.7 Battery maintenance
Within the electronics a battery is present. This battery is used only for the internal clock. If a
meter is installed and operating from an external power supply the battery will not be used. If a
meter is shut down or on stock than the battery will power the internal clock. The following
maintenance actions with respect to the battery should be taken:
• Replace the battery after 10 years of service.
• Replace the battery after 1 year on stock (or powered down).
In case of problems with the battery the metrological performance aspects of the flowmeter is
not at risk as critical data is stored in flash memory. However, in this case the internal clock will
be reset with each power up. A reset of the internal clock indicates that the battery is out of order
and replacement of the battery is required.
