Bulk NB IOT Water Meter
Bulk NB IOT water meter is a kind of intelligent water meter which can be read remotely and controlled by valve. It communicates with the server directly through the narrow band Internet of things (nb-iot). The installation cost is low, the equipment installation is simplified, the remote automatic meter reading of water meter is realized.
Advantages
1. Remote reading: periodically and regularly take the initiative to read the report.
2. Remote valve control: remote valve closing and opening.
3. Prepayment: support prepayment and pre order quantity, and close the valve in arrears.
4. Early warning system: battery undervoltage, abnormal measurement, prepaid use up to the threshold and other alarm prompts.
5. Step water price: different benchmark price and step price can be set.
6. Ultra long life combined battery: Standard er26500 Battery + spc1520, ensure more than 6 years of use without replacement.
7. Internal / external antenna: support internal / external antenna, stable and reliable signal, full coverage, no blind area.
8. High sampling accuracy: Based on our module photoelectric, hall, reed, magnetic switch sampling water meter remote, reading accuracy can reach 100%.
9. Fault detection of clarinet.
10. Flexible setting of upload frequency: data upload cycle can be set to meet different user management.
11. Replaceable battery structure design patent: without opening the upper cover of the main body, so it is convenient to replace.
12. The system adopts BS architecture: no need to install client, browser login, PC and mobile phone can support.
