District Heating Leakage Protection System UMS-F

Principle

District Heating Leak Protection system UMS-F employs values of volume flow from two pulsing flow meters calculated regularly.

Two monitoring functions are employed with the fetched volume flow data for protecting the installation from leakage, as the UMS-F closes the cut-off valves when a leak is detected by any monitor.

 

 

 

Logging

System Diagram UMS-F

Alarm and Event log
UMS-F maintains a log of the most recent 250 events, such as Power Down, Power Up, Alarm and Error messages, Alarm Acknowledge and Autoreset, External Control Input change, State change and Sequence execution.
Jumper Log
UMS-F maintains a log of the 15 most recent changes to the jumper settings.

These logs serve to document events surrounding actual incidents in the installation.

AERS

UMS-F attaches 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 alarm may be remotely acknowledged from the recipient's smartphnoe, tablet, laptop or PC.
