Supply Water Leakage Protection System KMP-V

System KMP-V Application:
Domestic and commercial installations

  • Kamstrup MULTICAL®61/62 water meter
  • Stainless Steel Cutoff valve
  • For MC61/62: Data Interface Module
  • KMP-V flow computer with 12 months
    attachment to AERS
Ill.: system KMPV-1,6-V1

Monitoring Functions

Issued when the volume of a single, continuous discharge exceeds a preset limit.
A discharge is considered continuous as long as its indicated flow exceeds the preset cut-off value, or as long as the indicated flow does not decline (PSALM®)

Seepage Alarm:
Issued when the flow of the installation fails for an entire test interval (normally 24 hrs) to drop below a preset limit.

System Error:
System Error Alarm is issued when the cutoff valve fails to close tight, when an internal voltage supply fails, when the Kamstrup MULTICAL® reports an error, and when no flow is registered for an appreciable time out of Holiday mode, or in Hi consumption phase.
System errors cause no installation cut-off.

Operating Modes:
Monitoring employs different sensitivities in High and Low consumption phases. Switching between phases can be manual (Holiday button), automatic via AIA (burglar alarm), or automatic via attached PIR motion sensors.
When 'Free Discharge' is activated, the current discharge limit may be exceeded without raising an alarm; this condition is revoked automatically upon expiry of a pre-set time, or if the key is reactivated before that.

KMP-V can perform an automatic run-in over a 14-day period. During run-in, KMP-V stores flow data for analysis and does not monitor the installation.
Run-in complete, KMP-V calculates monitoring parameters accoring to the observed consumption. Depending on internal jumper settings, one or more of these parameters will be instated when run-in terminates.

Alarm Functions

On leakage errors, system KMP-V cuts off the installation, issues alarm visibly and audibly at the front panel, and deactivates the alarm relay.
System errors are reported via an alarm relay, and visibly and audibly if possible.
Valve errors are reported visibly. In the Low consumption phase, leakage alarm relay action may be postponed until termination of the phase.

Valve Functions

A number of different valve functions are possible depeding on external signals from burglar or fire alarms, door switches on fire hose cabinets, valve switches on free-hanging fire hoses, or attached motion sensors. Furthermore, KMP-V may be supplied with a spring-return type cut-off valve, and is thus able to meet particular requirements from various authorities.
