ZK-GM-203P NB-IoT smart gas meter
Smart Gas
NB-IoT Smart Gas Meter
Product introduction
Membrane gas meter, the user's gas wheel reading is read by photoelectric type, and managed through the NB reporting platform.
For new installation areas. Perform remote meter reading of gas meters, collect and statistically analyze real-time cumulative consumption, calculate user gas consumption and calculate gas fees, and each gas consumption can be traced and traced.
For gas in arrears, it can be remotely switched on and off to prevent malicious arrears.
Provides a user binding function, which binds the user's contact information and payment method to the gas meter, which is convenient for the management personnel to manage the payment.
Provide an alarm for abnormal operation of the gas meter, and alarm for the illegal opening of the cover of the gas meter to ensure the safety of gas consumption.
Features
Deep network coverage, wide link, low power consumption, stable, safe and reliable communication.
