Info codes
The info codes consist of seven 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 described below:
Infocode - ERROR
This info code is not used.
Infocode - LEAK
This info code activates if the water in the meter is never stagnant. Possible un-tight connections, running
cisterns, un-tight safety valves in hot water tanks, or other leakages will have the result that the meter
registers water flow 24 hours a day.
If the water meter has not registered minimum 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 sensitivity 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 the water meter will set an alarm
for this 24-hour period. Users and water utilities must therefore, be critical of the leakage alarm.
