LoRa wireless remote transmitting water meter adopts LPWAN LoRa technology to provide users with a simple system that can realize long distance, long battery life and large capacity. The diameter for choice from DN15~DN200. 

1. LoRa technology has the characteristics of long distance, low power consumption (long battery life), multi node and low cost 

2. Integration of digital spread spectrum, digital signal processing and forward error correction coding technology to ensure the reliability of data transmission

3.Using high spreading factor technology and ultra high receiver sensitivity, it can effectively avoid noise, enhance anti-jamming performance and extend communication distance.

4. Super link budget allows the signal to fly farther, and it can achieve wider transmission range and distance at low transmission power.

5. It is easy to deploy and build the network, and the cost of node / gateway is low, the frequency of using license free band is low, and the cost is low.

Application advice:

In the LoRa system, the device can sleep anytime and anywhere, because it is an asynchronous protocol based on ALOHA. For those applications that are not sensitive to delay and do not have a lot of data to send, LoRa is the best choice.

8) RTC(Real Time Clock) calibration works in residential meter modules

9) Automatic error analysis 

10) Turn on or off metering period automatically according to surroundings. Decrease interface caused by same frequency.

System

1) Metering Modes: Automatically metering by remote Server or by Handheld. Any Meter could be used as a Repeater for the meters nearby for metering or commands transferring.

2) Working Mode: Meters work on the Carrie Wake Up mode to stand on a low power consumption status. On the standby current of less than 45 μA(which is the low power consumption status), the response time to communicate to a meter is not more than 8 seconds.

3) Meter Functional Status could be abled or disabled: to close valve if magnetic detected; to avoid of anti-rust; to activate prepayment function; to detect if removed from pipes.
