6. Battery and replacement procedures
The water meter constantly monitors the status of the battery (total discharge: 13 years*) and signals the imminent discharge by
displaying the icon
. The report takes place one year before the total download. For replacement contact the manufacturer.
*Battery life depends heavily on the working time window, set during the configuration process, and the environmental
conditions. The battery life estimate is provided by the configuration software.
The meter uses non-rechargeable batteries that, if misused with, can be potentially dangerous.
To reduce the risks, you should take the following precautions:
Do not recharge or replace the battery
Do not open, puncture or damage batteries;
Do not short-circuit batteries;
Do not expose batteries to temperatures above 85 ºC;
Do not insert into ovens, crush or cut: these actions could cause an explosion or leakage of flammable gases or liquids.
Do not use naked flames near the device;
Do not put in contact with water;
Do not expose the battery to an extremely low pressure environment which could cause an explosion, a gas or flammable liquids leak;
Always dispose of batteries in compliance with current regulations;
Always use original spare parts authorized by the manufacturer;
