Supply Water Leakage Protection System KMP-V-N
|
Principle
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®
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.

Logging
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.
|
AERS
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.
