A brief introduction to remote recharging water meters:
There are three main ways to implement smart water meters:
(1) Remote meter reading: M-BUS photoelectric direct reading water meter or RS485 water meter.
(2) Prepaid card swiping+485 meter reading: Prepaid remote water meter transmission.
(3) 485 recharge+485 meter reading: RS485 recharge water meter.
This product is of the third type. External 4-core wire for water meter: 485A, 485B, 9-12VDC, GND. The water meter can remotely control the switch valve through 485, and the recharge data encrypted by DES can be flushed into the water meter through 485. The relevant data of the water meter can be remotely read through 485, which is the latest integration of fully intelligent water meters.
The prepaid water sales management system consists of two parts: an intelligent water meter and a communication network. There are various communication methods for the communication network, including wired 485, wireless ZIGBEE, GPRS communication, and local area network. Multiple communication methods can be mixed in the system.
The main functions of smart water meters.
1) Read data information: water meter number, cumulative water consumption, remaining water consumption, switch valve status;
2) Insufficient remaining water and other fault information, the system prompts an alarm; Support water usage overdraft function;

3) Remote parameter setting function.
4) The equipment has moisture-proof function and can operate normally in humid environments or short-term water immersion;
5) Data protection function: When the water meter is powered off, the data is automatically saved and restored after power on;
6) Backend software: Filter low water user information and display it synchronously with the user's water meter;
