NB-Iot valve-controlled electronic direct drinking water meter adopts advanced narrow-band IoT cellular communication technology, no need to install collection equipment, and directly accesses the public network through mobile, telecom/mobile operators wirelessly, and users only need to deploy cloud platform meter reading system All kinds of data interaction can be easily realized, which is simple and efficient.

The product adopts dual-module and dual-battery power supply design. The metering module is powered by a 3V lithium-manganese battery and is responsible for metering, LCD display and NFC communication functions; the NB-Iot communication module is powered by a large-capacity 3.6V lithium-argon battery and is responsible for valve control and wireless communication. Function.

NB-Iot valve-controlled electronic direct drinking water meter has the functions of early morning staggered peak reporting and forced wake-up reporting, supports pre-paid and post-paid charging modes; supports remote valve control, has valve maintenance function, and can be read and set through the NFC function Related parameters.

The water meter is made of grade 304/316 stainless steel, which is hygienic and environmentally friendly, has no secondary pollution, is resistant to acid and alkali, and will not produce corrosion and exudate at high or low temperatures. It is safe and reliable, meets food-grade standards, and has high precision. , anti-interference, strong reliability and other advantages.

Features:

1、Data reporting function: Active peak reporting at 3 o'clock every day or forced wake-up through NFC function to report data；
2、Open and close the valve: control or maintain the valve through the NFC function or the platform to open and close the valve command;
3、NFC communication function: through the NFC function, you can set the address of the meter, the base number of the meter, the time of the metering module, reset the communication module, and turn on or off the automatic reporting function of the water meter;
4、Battery undervoltage warning prompt: the voltage status of the metering module and the communication module will be reported to the platform together every time the data is reported, the voltage of the metering module is represented by undervoltage, and the voltage of the communication module is the actual voltage value;
5、Remaining water alarm function, recharge amount reset, and water refund function after recharge;
6、The battery is easy to replace: the battery installation position adopts an independent battery compartment, which is convenient to replace the battery.
