How To Wire Four Wires of RS485 Remote Smart Water Meter
The RS485 remote smart water meter adopts a dry high-precision module and is equipped with an advanced photoelectric direct-reading sensor to achieve stable remote meter reading, which solves many difficulties brought by water supply companies for many years in household meter reading. The water meter does not consume electricity during the normal measurement process, and only takes a little electricity from the 485 bus at the moment of meter reading. Therefore, this product has the characteristics of low power consumption and long life.
For users who just bought the RS485 remote smart water meter, the wiring method is stumped. We know that RS485 is a water meter port, and the protocol has MODBUS (default 9600 baud rate) and CJ/T-188 protocol (default 2400 baud rate). There are 4 black, blue, yellow, and red wires at the outlet of the water meter signal line, and it is necessary to strictly distinguish the positive and negative wiring. The requirements for on-site construction are relatively high, and the requirements for renovation are relatively high. It is suitable for school dormitories, industrial parks, factories, apartments, commercial complexes, etc. Use RS485 transmission line to connect multiple water meters with protocol converters and concentrators to establish a data transmission network. RS485 remote intelligent water meter, save the cost of water meter price.
RS485 remote intelligent water meter concentrator collector can connect 200 water meters individually. When the number of devices is too large, the number of collectors needs to be increased. If the equipment increases, or the interference source is uncertain, it is necessary to increase the amplifier (repeater). All in all, this wired meter reading solution is more troublesome than wireless water meters in the early stage, but the stability of meter reading in the later stage is far better than that of wireless remote water meters.
