Wireless AMR Water Meter(LoRa)

LoRa wireless water meter using of advanced wireless transmission technology, it transforms metered information of conventional mechanical water meter into electrical signal have it stored by micro-electronics control circuit. It is able to automatically read the metering data via wireless remote network and control the close / open of the valve.

1.Measuring Method: Use of detection mode by double reed switch, preventing effectively the error caused by the electromagnetic interference and the pulse jitter.
2.Communication Mode: The communication module is in dormancy mode at ordinary time, it comes to life with a very short time each minute and it detects if there is wireless commands or not. If detected, it starts the receiving function and receives the data; If not, it enters into sleeping mode. By this way, it drastically reduces the average po consumption of the module that effectively prolongs the battery life

3.Working temperature: cold water meter: (0.1 ~ 30)℃ ; hot water meter: (0.1 ~ 90)℃.
4.Working pressure: ≤ 1.0MPa.
5.Pressure loss: ≤ 0.063MPa.
6.The installation environment: Class B.
7.Electromagnetic environment: E1 - residential, commercial and light industry.

8.Operating current: static electricity <19uA.
9.Flow profile sensitivity level: U10, D5.
