Introduction
LoRa wireless water meter using of advanced wireless LoRa 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 is also able to transfer the data to the back-office system (data center) after reading the meters. And the administrator can remotely control the user's water meter valve when the user refuses to pay the fee.
The water meter uses LoRa modulation technology for data transmission and reception, with ultra-low power consumption and long transmission distance. It greatly surpasses the GFSK modulation method in terms of stability, anti-interference ability, and receiving sensitivity. It solves the problem of taking into account long-distance transmission, anti-interference and low power consumption at the same time, and is the best choice for wireless applications with long-distance transmission and high reliability.
The meter can be automatically maintained, does not require construction wiring, does not require professional maintenance, and is simple and convenient to install and use.

FEATURE
◆Waterproof level: IP68
◆Accuracy: Class B
◆Short distance communication, so the power consumption is low.
◆The administrator can actively send the instruction of meter reading or on-off valve to the water meter form the platform through the concentrator to achieve the purpose of real-time control.
◆The cost of use is low, only concentrator need use sim card. Water meter no need.
APPLICATION
Suitable for almost all types of water supply. Lora system is for water meter installation intensive environment, such residential quarters, apartments, high-rise buildings and so on.
