NB smart water meter

Product name: NB-IoT smart water meter
Product introduction:
The electronic pulse-type water reading is obtained and managed by the NB reporting platform.
For new installation areas. Remote meter reading of water meters, collection and statistical analysis of real-time cumulative usage, calculation of user water consumption and calculation of water charges, each water usage can be checked and traced.
Remotely switch on and off the meter to prevent malicious arrears.
Provide user binding function, bind user contact method and payment method to water meter, which is convenient for management personnel to manage payment.
Provide alarms for abnormal operation of water meters, and provide alarms for illegal opening of water meters and reversed water meters to ensure water safety.
Product features: Deep network coverage, wide link, low power consumption and other advantages, stable, reliable and secure communication
