Dynamic battery life calculation

NOTICE

Change battery

Erroneous calculation of battery life

● The number of batteries must be configured using the service software when replacing

batteries. This ensures that the meters can correctly calculate battery life.

● The date (month, year) the batteries are replaced can also be read out remotely via the

M-bus wire or M-bus RF.

Dynamic battery life calculates the probable remaining battery life.

The calculation is based on meter consumption and configuration. Any change to the

configuration is automatically applied to battery life. If the meter determines energy use is

higher or lower than expected, it lowers or increases its battery life.

Important:

Replace ALL batteries at the same time for an accurate calculation.

Communication

Meters are equipped with an optical interface and two water meter pulse inputs as standard.

You can use one of the following communication modules to remotely read out data:

● Pulse output module

● M-bus module

● RF module

The modules do not impact the acquisition of consumption data. You can upgrade the

modules at any time without violating the security seal.

Communication module

The communication modules are connected to a reaction-free plug that can be installed or

updated at any time.

Compliance with ESD regulations must be ensured.
