Monitoring Functions
Leakage:
Leakage alarm is reported if the flow difference exceeds the selected threshold
for two consecutive measuring periods each a maximum of 210 seconds duration.
ALOHA®:
The patented ALOHA® mechanism permits the
passage of air pockets through the flow meters without causing false alarms
and without reducing system sensitivity. System KMP-K thus offers optimum
reliability.
Seepage: (OptiTight®)
The patented OptiTight® mechanism if desired
performs one or more times daily a check of the installation tightness, whereby
seepages on the order of the flow meter cut-off are detected.
System Fault:
When a valve is closed, during OptiTight® or by an
alarm, KMP-K checks its tightness. If it fails, a System Fault Alarm is reported.
System Fault Alarm is also reported for voltage supply failures, and functional
failures reported by the Kamstrup MULTICAL®.
System faults do not close the cut-off valves.
Alarm Functions
KMP-K will cut off the installation on detected leakage, issue an alarm audibly
and visibly, and drop the alarm relay.
Valve errors are reported visibly and logged.
Other system faults are reported via the alarm relay, plus audibly and visibly if possible.
Leakage Alarm from KMP-K may be read out via any communication module in the INFO code from
MULTICAL® 801 s/w rev. D1 or newer, and via M-bus, LON and
GSM/GPRS modules in info bits from MULTICAL®603 or 803.
