1. Adopt convex surface resin antifreeze glass, effectively prevent the glass from cracking at low temperature.
2. LCD function: LCD screen real-time displays of the remaining amount of water, current consumption, signal strength, previous consumption, previous accumulated amount, current unit price, billing type, valve status, at the same time reserves the mechanical display way, convenient for users to view the status of the meter in real time.
3. Low power consumption and long service life: adopting industrial ultra low power NB-IoT/LoRa module and large-capacity lithium batteries, the battery life is more than 6 years and the data can be stored for up to 30 years.
4.Easy installation, no collector and concentrator, no wiring(NB-IOT water meter).
Communication mode

Description and featureApplication:Used to meter and control the total volume of water flowing through tap water pipes.
Working principle:The Internet of things water meter is a water metering instrument which is comprised of ordinary mechanical water meter as the base meter, together with metering and acquisition part, control circuit and wireless communication module.
The Internet of things water meter can be used as NB-IoT and LORA communication mode, and can be adopted as two forms of water meter with valve control and without valve control.
