Leak surveillance
Water installation
MULTICAL® 62 can monitor the water consumption. Possible running cisterns, leaky heating spirals of tap
water tanks, or other leakages, will result in water flow being registered from the water meter 24 hours a
day.
If MULTICAL® 62 does not detect for example at least 1 continuous hour (60 minutes)/day, without pulses
from the water meter, this may be the sign of a
leak i the ate s ste . I fo
will be displayed (info code
64), and an alarm will be sent via remote communication.

Note: N=2 is default value in connection with leak surveillance. Increased sensitivity, e.g. N=3, can only be
achieved by means of METERTOOL.
Users must be aware that water consumption can occur during the night too in connection with lavatory
visits in households with many residents. Thus, hours without counting may not occur, and MULTICAL® 62
will therefore set an alarm for these 24 hours. Users and water works should therefore not be uncritical
towards the leakage alarm of MULTICAL® 62. The alarm will dissappear automatically after 24 hours with at
least one hour without counting (at N=2), and after this the event will only appear from the info logger.
When the leak function is activated in MULTICAL® 62 (N>0), input VA of the base module cannot be used,
and therefore it is only possible to connect one extra meter (e.g. an electricity meter to input VB). If the
function is inactive, it is thus possible to connect two extra meters (e.g. an electricity meter and a water
meter).
Receipt of alarm messages
When the meter has registered a leakage, it can send an alert message to a receiving station, where
incoming alarms are processed, according to an encoded action pattern determined for each customer.
E.g. sta ti g ith a “M“ essage to the usto e s o ile p
hone, parallel with the person on guard
receiving the message. Regular data readings from MULTICAL® 62 to receiving station/control centre
ensure that defective remote reading, if any, is detected.
Max. flow
MULTICAL® 62 makes it possible to keep an eye on the max. flow on a monthly basis. The max flow is a
measure of the maximum water flow in the system, at a given consumption pattern. If the max flow
decreases over time, this may indicate a leakage in the residential service pipe.
