If several devices are installed in a unit, the installation conditions must be the same for all devices in order to ensure the most
equitable billing of consumption possible.
Carefully observe the instructions in the data sheet, instruction manual, application notes and lid. Failure to comply with the
operating conditions may result in situations of danger and forfeiture of all claims of liability for defects and liability on the
basis of any guarantees expressly granted. Further information is available on www.bmeters.com
Dispose of replaced devices and defective components in accordance with current environmental regulations.
Do not damage the device casing. In the event of blunt objects hitting the front of the display, it can be damaged irremediably
and lose the degree of protection IP65 or IP68. Install in areas protected against impact. In case of breakage of the protective
casing contact customer support.
The meter is not suitable for running water in central heating systems but is suitable for clean water.
Pay attention to sharp edges or sharp projections in the threads, flanges and measuring tube. Therefore, it is recommended
to wear protective gloves.

If transmission network interfaces are used, especially when cables are routed outside the building, use more protection
against electrical interference.
In case of danger of frost, empty the system and, if necessary, remove the meter.

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 appliance should not be disposed of with household waste as it consists of different materials that can be recycled at the
appropriate facilities. Inquire through the municipal authority about the location of the ecological platforms to receive the product
for disposal and its subsequent proper recycling. The product is not potentially dangerous to human health and the environment, but if
abandoned in the environment impacts negatively on the ecosystem. The crossed-out bin symbol on the label on the appliance indicates
that the product complies with the legislation on waste electrical and electronic equipment. The abandonment of the equipment in the
environment or the improper disposal of the same is punished by law.

Battery life max 13 years***
Cut-off The meter does not count volume below 1/3*Q1
Permitted installations 
* IP68: maximum 24 hours continuous immersion at 1 m depth.
Note: In case of damage caused by accidental impact, the meter must be replaced
with a new one, to restore the degree of protection.
** In optimal propagation conditions, the radio range depends on physical conditions
(building construction, climatic conditions...) where the propagation of the radio signal
can therefore vary.
*** Battery life depends heavily on the working time window, set during the configuration
process, and the environmental conditions. The battery life estimated is provided by the
configuration software.
