Smart Monitoring
To maintain the stable operation and performance of flow meters,
EMS Smart Water Meter is equipped with three smart monitoring functions:
-N Days: Operation Days, the number of days that the water meter has been operating.
-B Days: Battery Power Shortage Days, the number of days that the battery is in low power.
-Overload Times: The number of times that the instant rate value is higher than
Qmax(overload flow rate).
