LXSY-NBIOT Intelligent Water Meter

summary

NB IoT smart water meter is a remote transmission water meter developed for the practical needs of intelligent management of water supply companies, which is convenient for remote meter reading and control. It adopts our company's direct reading water meter as the measurement basis, and automatically communicates with the network through NB IoT network to achieve automatic remote meter reading of the water meter usage, effectively avoiding the need for management departments to come to the door for meter reading. This product also has valve control function (optional), which facilitates the management department to control the water usage of the water meter, making remote meter reading and control more convenient and reliable. While saving manpower, material resources, and financial resources, it effectively improves production efficiency.
This NB IoT smart water meter complies with the technical requirements of GB/T778-2007 "Measurement of Water Flow in Closed Full Pipelines - Drinking Cold Water and Hot Water Meters" and CJ/T224-2012 "Electronic Remote Water Meters". The communication protocol follows the "130 Communication Protocol Specification" and can also be customized according to user needs.
