15814469667 Ms.ChenNB IoT water meter is a wireless remote water meter based on NB IoT narrowband Internet of Things communication. Through NB IoT Internet of Things, the water data of intelligent water meter is transmitted to the meter reading and charging management system. When the user is in arrears or stops reporting, the management system sends a valve closing command through NB IoT Internet of Things to achieve automatic water control. It is an ideal metering product to improve the modern management level of water supply departments, The remote prepayment function can be realized by combining the valve control function.
