Supply Water Leakage Protection System BBU/BXU
Kamstrup

Principle

Supply Water Leakage Protection System BBU/BXU employs values of volume flow from an ultrasonic flow meter, which is interrogated at regular intervals via a data interface in a Kamstrup MULTICAL®61/62 Water Meter, to which the flow meter is attached.

Two monitoring functions are used with the collected volume flow data for leakage protection of the installation, in that System BBU/BXU closes its cut-off valve when it detects a leakage.

Component errors reported via the Water Meter INFO code are propagated by the KMP-V as System Errors.
