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 is activated if the water in
flowIQ® 3100
is never stagnant. Possible untight connections,
running cisterns, untight 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 1 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 hou
r
without flow in the meter.
The sensivity of the leak surveillance can be selected by the customer when submitting the order. 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 an hour 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.
