Leak Days
Tamper Proof
EMS Smart Water Meter owns 3 tamper proof functions,
including O Days, H Days, and U Days.
-O Days: Static Days, the number of days that no flow is detected.
-H Days: Magnetic Interference Days, the number of days detecting magnetic interference.
-U Days: Reverse Days, the number of days that reverse flow is detected.

Static Days (O Days)

Magnetic Interference Days (H Days)

Reverse Days (U Days)
Minimum Night Flow
To precisely detect leakge and maintain water balenace,
EMS Smart Water Meter can record the water consumption of
3 specific durations at night, including L1, L2, and L3.
-L1: The default setting is 03:30~03:35, parameters are configurable
for pipeline leakage detection.
-L2: The default setting is 03:00~04:00, parameters are configurable
for supply network/ DMA management.
-L3: The default setting is 01:00~05:00, parameters are configurable
for maintaining water balance.

L1: 03:30~03:35  
(Pipeline leakage)

L2: 03:00~04:00 
(Supply Network/DMA)

L3: 01:00~05:00 
(Water Balance)
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).
