LoRa/NB-IoT wet IoT water meter
DN 15-50mm
IoT remote transmission water meter consists of remote transmission base meter, wireless communication module and other components. wireless communication module
The block automatically sends the user's daily (customizable) water consumption data directly to the mobile phone through the base station or gateway.
In the cloud data server, the table communicates directly with the backend server.
Product Features
◆ Automatic data return: The water meter integrates NB-1OT, LORA, and 4G IoT modules, and automatically sends user water meter data directly to the cloud data server through the network
◆ Simple network structure: Using the public network, there is no need to build your own Network, the table side directly communicates with the background server to send data discretely: a special data return time setting mode can fix the data sending time. Determined to send discretely at a specific period of time to avoid data loss caused by data concurrency. Historical data can be queried on the table side: In order to avoid data loss due to poor network signals and other reasons, the data will be stored on the table side.
◆ Freeze data: To avoid data loss, The 30-day historical data is frozen on the meter side and can be read by issuing commands.
◆Settlement day data: Settlement day data can be set on the meter side and read.
◆SIM card number reading
◆ Abnormal status alarm: The wireless electronic unit stores the currently collected water meter data, as well as the operating status of the water meter, such as: whether there is strong magnetic interference, whether there is undervoltage, whether there is reverse flow, etc. Split structure: the electronic part is recyclable use
Technical parameters
◆Power consumption: Quiescent current power consumption is less than 20μA, maximum wireless current transmission power consumption = about 220mA
◆Wireless performance parameters: Frequency band information: 850MHz/900MHz/800MHz/700MHz
Maximum output power: 23dBm±2dB
Acceptance sensitivity: -129dBm±1dB
◆Power supply: 3.6 lithium battery, design life of more than 10 years
◆Sampling method: Hall sensor, double pulse, pointer sampling at 0.01, forward addend, reverse subtractor
◆Data reporting: Working mode: Active reporting, time can be set Debugging mode: Trigger reporting, the trigger point is below the crescent sensor, using magnets to trigger alarms: reverse, strong magnet, low voltage, disassembly and other alarms
