Supply Water Leakage Protection System KMP-V-N


Supply Water Leakage Protection System KMP-V-N employs flow measurements calculated from the output from a high-resolution pulsing ultrasonic meter of DIEHL or KAMSTRUP manufacture.

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

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-N 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-N 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.


On delivery, KMP-V-N is attached to the DanTaet Alarm and Energy Registration System AERS, which conveys leakage alarms to the duty watch of the property and illustrates the event. AERS transmits alarms in the form of text messages and/or e-mail, and alarms may be remotely acknowledged from the recipient's smartphone, tablet, laptop or PC.

Example: situation view from AERS.

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 power failure.
Variant -V1LPWAN is equipped with LoRa® communication equipment.
