Used for remote wireless meter reading, compatible with Itron water meter and gas meter, low power product integrating non-magnetic measurement acquisition and communication transmission, the product can resist magnetic interference, support NB-IOT or LoRaWAN wireless remote transmission function;
The LoRaWAN module helps to optimise usage of natural resources in the gas metering industry and gain substantial productivity.
Features:
l Battery power supply: last 10 years lifetime
l NB-iot supported working band: 700\850\900\1800MHz or nB-iot band supported by local operators, no need to apply for frequency points; LoRaWAN supports the following frequency bands: CN470, EU868, RU864, IN865, and AS923
l Support touch button to report the data
l With magnetic attack alarm,low battery voltage alarm and disassemble alarm function etc.
l Valve position switch status detection, valve control circuit, automatic dredge valve, support for near end maintenance, etc.
l The daily and monthly frozen data can be saved and queried at any time
l Support infrared parameters configuration and upgrading function
l The data will be saved when the power is off.
l IP67 protection degree
l With CE & FCC certification
l Easy installation, high reliability and strong expansibility.
