Working Mode
LOP1: Real-time wake up remotely, response time(open/close valve): 12s, ER18505 battery life: >8 years
LOP2: response time(close valve): Max 24h, response time(open valve): 12s, ER18505 battery life: >10 years
LOP3: response time(open/close valve): Max 24h, ER18505 battery life: >12 years
Battery Life Calculation
ER18505 battery capacity: 3.6Ah, average power consumption of module: ≤ 20μA。
1. Battery life in Hours:3.6Ah = 3,600,000μAh
3,600,000 ÷ 20 = 180,000(hour)
2. One year in Hours: 24 × 365 = 8,760(hour)
3. Battery Life in Years: 180,000 ÷8,760 ≈ 20.55(year)
20.55 × 50% ≈ 10.27(year){If using 50% only}
Description :
Flomarvel LoRa wireless smart valve is an all-in-one battery operated valve of superior quality and of exclusive design with embedded LoRa LPWAN wireless technology. With its ultra-low-power consumption, the valve can operate on batteries during 11+ years and through extreme long distances from the gateway/concentrator with an exceptional obstacles penetration. With its additional Digital and Analog inputs, like a pressure or a humidity sensor, for instance, the valve can be turned off at the main line stopping the leak before major damage is done and at the same time, send an alarm to your Mobile through the gateway or the Application Server. The valve may also be configured for full water meter reading and data transmission capabilities, eliminating the need for a discreet endpoint.The STREGA Smart-Valve can be programmed for automatic shut-off based on counter value.
