Data communication
The meter has built-in communication as Wireless M-Bus, Sigfox or Wired M-Bus.
Note! It is one-way data transmission
from
the meter
–
no data receipt in meter.
20.1
Transmission
Data packages are sent at intervals of approx. 16 or 96
seconds. Every eights package is a full data string, whereas
the 7 intervening packages are compact data strings. Sigfox data packages are sent on a daily basis.
The nominal transmission power is:
Drive-by mode:
10 Mw
Fixed Network:
25 Mw
IoT/Sigfox:
19 Mw
Note! The content of the data package is updated at every transmission.
20.2
RADIO OFF
Radio transmission has been interrupted if ‘RADIO OFF’ is displayed.
RADIO OFF is activated at the end of the production process at Kamstrup A/S. The meter removes RADIO OFF
automatically, when the volume register has counted water consumption for approx. 5 seconds.
RADIO OFF is intended for situations where radio transmission is inappropriate
–
e.g. in laboratories, in warehouses
and during air transport, where many meters will typically be concentrated in one place.
It is not possible to stop the radio transmission of a meter in normal operation permanently, but the meter can be
turned OFF by means of the optical eye e.g. in advance of air transport. However, the radio will automatically turn
ON again, as soon as a water flow is registered.
RADIO OFF secures that the meter does not send radio communication until the meter is put into operation for the
first time.
20.3
Data content
The data package in the data transmission partly depends on the communication module configuration, chosen
when ordering the meter.
Some reconfiguration of the data package and change of the communication module can be done afterwards, with
the software program ‘Datatool’
Module number in the configuration is: 031-
XX
-XX-X-X
Details and information about data packages and communication modules are available on Kamstrup web page.
20.4
Encryption
flowIQ® 3100 can be ordered without or with encryption
*)
of data transmission.
If encryption of data is selected, it
consists of 128 bit AES counter mode encryption. Kamstrup A/S recommends encryption.
*)
Meters produced for Russia will always be WITHOUT encryption.
