Info codes
The info codes consist of 7 separate text signs (framed in the above sketch), which indicate a special condition in
the meter. The signs flash when active. If not, they are OFF.
The individual info codes are described below:
Info code - ERROR
This info code is not used.
Info code - LEAK
This info code activates if the water in the water meter is never stagnant. Possible un-tight connections, running
cisterns, un-tight safety valves in hot water tanks, or other untightnesses will have the result that the meter
registers water flow 24 hours a day.
If the water meter has not registered minimium one continuous hour without water flow within the latest 24 hours,
this is a sign of a leakage in the water installation. The alarm automatically disappears after an hour without flow
in the meter.
The sensivity of the leak surveillance can be selected by the customer when submitting the order, and later by
METERTOOL. The following options are available:

The utility must be aware that there can be water consumption all the 24 hours in households with many residents.
This means that there will not be any hours without flow, and flowIQ® 3100 will set an alarm for this 24-hour period.
Users and water utilities must, therefore, be critical of the leakage alarm.
The leakage alarm is saved with a date stamp in both daily register for 460 days and in monthly register for 36
months. Furthermore, it is saved in the info code register of the latest 50 info code events. Together with the info
code event a time indicator with 7 time intervals, which indicates how long the info code has existed, is registered.
The Wireless M-Bus signal includes the LEAK code. If the LEAK code is active, or has been active within the latest
30 days, a time indicator with 7 time intervals will indicate how long the info code has been active.
