● Function Description
※ LCD display: The LCD screen can display information such as the remaining water level, cumulative water level, on/off valve status, low battery alarm, and abnormal water meter prompt of the water meter.
※ Prepaid function: Remote purchase of water first, followed by use of water, and automatic valve closure after use through RS485 network.
※ Remote meter reading and control: Remote meter reading, querying, and control can be achieved through Ethernet or GPRS unlimited.
※ Water volume alarm function: Users can set the water meter to close the valve alarm when a certain water volume is reached according to their own requirements, reminding users to purchase water in a timely manner.
Sealing function: Water meters are physically sealed, with good sealing, and can work normally in water for a long time.
Low power consumption: Static working current ≤ 4 μ A (when powered by a battery), battery life>6 years.
● Internet connected water meter method:
※ Centralized card reader card swiping: Connect all water meters to the centralized card reader through an Ethernet cable, and use the centralized card reader to sell water, query, and control the on/off valve.
※ Computer software management: The centralized card reader is connected to the computer infinitely through a 485 Ethernet cable or GPRS, and can be used to sell water, query, print, and control switch valves through computer management software.
