Supply Water leakage Protection System KMP-V


Supply Water Leakage Protection System KMP-V employs flow measurements from an ultrasonic meter, fetched regularly via a digital interface from a Kamstrup MULTICAL®61/62 water meter, to which the flow meter is attached.

Two monitoring functions are used together with the fetched flow values for protecting the installation from leakage, as the KMP-V closes the cut-off valve when a leak is detected by either monitor.

Component errors reported in the water meter's INFO code are propagated by the KMP-V as System Error Alarms.


System Diagram KMP-V


PSALM® is a data processing method using the flow spectrum to dynamically calculate discharge, so that this may decline when flow reduces.
Thereby in a given installation operation will be possible at a lower alarm limit or, given an alarm limit, more consumers can be tolerated.

PSALM® can also compensate to a degree for the data reduction resulting from limitations in time or volume resolution of a flow meter.


Alarm and Event log

KMP-V maintains a log of the 250 most recent events and alarms, such as power down/up, alarm- and error messages, acknowledgements and automatic resets, key input, control signal changes, state changes and sequence execution.

Jumper log

KMP-V maintains a log of the 15 most recent setting changes of the internal jumpers.

These logs contribute to the investigation and documentation of actual events.

Variant -V0 is used where cut-off on alarm is not permitted.
Variant -V1SRNO is used where the cut-off valve must open in the event of mains power failure.
Variant -M0 is used where an MC61/62 billing meter may be employed.
