Product Description

Brief introduction
LoRa wireless water meter adopts advanced wireless transmission technology, which transforms information of conventional mechanical water meter into electrical signal that stored by micro-electronics control circuit. It is able to automatically read the metering data via wireless remote network and control the close and open of the valve
Brief introduction
The prepaid water meter have mechanical and electronic readings. It is used to control users overspend by prepaying with an IC card. Pay in advance and then use water get rid of the inconvenience of on-site meter reading and charging.

Advantage	Transmit information through IC card, charge accurately Install and operate easily	LAN transmission data, low power, Suitable for intensive installation real-time reading control	Wide area network, data transmission without distance limitation, simple installation and debugging, low sample order cost.	Wide coverage, low power consumption, low cost and slower rate.
Limitations	The stand-alone version of the software can only be read and controlled on a designated computer. Back up user data when replacing a pc.	Greater impacts by obstacles and limited communication distance(up to 1 km).On-site debugging is a heavy workload	Occasionally there will be data packet loss, high transmission rate, relatively high power consumption.	At present, NB technology is not fully mature and the coverage of base stations is low.
