MULTICAL® 21 & flowIQ® 2101 /..02 /..03 TECHNICAL DESCRIPTION
Kamstrup A/S •Technical Description • 5512-897_J1_GB • 06.2016 47
A ‘full string’ includes extra information on how the meter data are to be interpreted. When a single ‘full
string’ has been received once, the remaining meter population of identically configured meters can be
read, by a ‘compact string’. When sending a data package each 16 seconds, the data package is short and
compressed to achieve a long battery life.
By 96 seconds intervals, a long and intelligent radio package with built-in 'repair coding' is sent. At the
same time, the power of the signal is higher and therefore optimized for use in fixed networks. With the
increased interval between the transmissions, the same high battery life is guaranteed.
The table below summarizes and describes the data comprised by the Wireless M-Bus data package:
The meter’s serial number. The serial number will never be encrypted.
Identification as cold water meter
Kamstrup's specific Wireless M-Bus producer-ID
Information on length and format of data package
Information on encryption of data package
The current meter reading from the meter's legal register
Meter reading of the 1
st
of the month if the 'R' value 1, 3, 5 or 7 is selected
*)
Maximum flow, which has been measured in the last completed month,
respectively 24 hours, provided the 'R' value 2, 4 or 9 has been selected.
Minimum water temperature for the last completed month or day depending on
the choice of the 'R'
Minimum, maximum or average ambient/meter temperature, latest month or
24 hours – depending on choice of ’R’- value
Info codes which are active at present
Info codes which have been active within the latest 30 days including
information on how long they have been active – on a scale of 1-7
For more information - See section ‘Optional register in data logger’

(applies not to flowIQ 2103)
If encryption has been selected, when submitting the order, all variable data will be encrypted with 128 bit
AES counter mode encryption. Kamstrup A/S recommends encryption.
If the meter is configured for Wireless M-Bus mode T1 OMS, data transmission will only take place every 15
minutes – four times per hour.
Kamstrup does not offer reading devices for Wireless M-Bus mode T1 OMS.
