Installation of Electronic Water Meter + Wireless Outdoor Display This is Koreaâ??s first electronic water meter that is embedded with a wireless communication module, which requires no connection between the water meter and the outdoor display. Traditional water meters use communication lines to connect to external displays, making the installation difficult and costly. Also, the limited installation space results in inefficient meter-reading. The SES electronic water meter is equipped with a wireless module inside, which does not require any extra communication line work to connect to the outdoor display. This means that installation costs can be significantly reduced by just attaching it to a wall without the need for any installation work, and space is not limited, which helps to improve the meter-reading environment.
