Supply Water leakage Protection System KMP-V
Kamstrup

Principle

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.

Logging

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.

Variants

Variant -V0 is used where cut-off on alarm is not permitted.
Variant -V1ss is used where a stainless steel cut-off valve is required.
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.
