counter
The leak detection is performed by analyzing a number of occurrences (configurable by register: S330 and S331) where the calculated flow rate
is less than a leakage threshold (configurable by register: S328 and S329).
The associated leak alarm is stored and transmitted with the next daily frame.
The alarm is automatically deactivated after the daily frame is sent.
The settings associated with this mode of operation are:
•
Enabling and Configuring inputs (register 320)
•
History configuration (register S321)
•
Anti-bounce timer period (register S322)
•
Flow calculation period (register S325)
•
Leak thresholds (registers S328 and S329)
•
Null flow period counters (S330 and S331)
A complete list of the registers can be found in paragraph 3.4.
