Supply Water leakage Protection System BI

Operating Principle

Supply Water Leakage Protection System BI performs continuous flow measurements using the attached flow meter with medium-speed pulser.

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

Errors with the attached components are propagated as System Error Alarms.
