RS-485 wired meter reading scheme

RS-485 scheme is a wired transmission scheme. Because it connects the electricity meter and data acquisition equipment through signal lines, it is suitable for small-scale centralized installation of electricity meters, such as hotels, office buildings, schools, residential quarters, etc.

NB-IoT/4G Scheme

It is not limited by the installation distance of meters. As long as there is a signal at the installation position, it can realize remote meter reading regardless of whether the meters are installed in different areas or cities. It has been widely used in factories, industrial parks, shopping malls, schools and other places.

Power Carrier Line Scheme

It is suitable for occasions where there are not many transformer areas and electric meters are installed dispersedly. This kind of meter reading scheme can be selected in scattered scenes such as shopping malls, villas and parks.

Radio Frequency Scheme

It is suitable for scattered installation of electric meters, such as shops, parks, factories, etc. No wiring, stable signal transmission and strong anti-interference ability.
We devote ourselves to professional research, production and sales of all series of electric energy meters, data concentrator units, static watt-hour meter products.
