Datagram
The datagram in flowIQ® 2101/3100 M-Bus water meter has a fixed data content.
Previously, Kamstrup has placed a number of special registers like configuration values in the manufacturer
specified part of the telegram. This has required quite extensive knowledge of the meter in order to decode and
format these data correct.
In order to be able to decode special data registers in an easier way, Kamstrup has taken the approach to define a
number of manufacturer VIF extensions – so called VIFE. The outcome is that most reading systems can show the
special registers in clear reading.
Below an example showing manufacturer specified data vs. Manufacturer specified VIFE:
