Meter reading

Smart meters are crucial components of the Smart Grid and enable two-way communication by interfacing remotely
with the utility and deliver meter readings automatically.
By gathering and forwarding data, smart meters allow consumers to make informed decisions to alter usage and
optimize electricity consumption. It also helps utilities to better monitor the electric system and demand response to
reduce peak loads, prevention of outages.Through the connection with MB706, all the serial data will be sent to
SCADA software via LTE CAT M1 and NB-IoT network.

Remote intelligent meter reading

Remote intelligent meter readingMay 05,2022

In nowadays, the large number of various meters are dispersed in different locations, some of which are remote and difficult to access, a remote meter reading system is urgently needed to relieve staff of utilities from heavy but inefficient tasks.Traditionally, the utilities companies used to hire thousands of meter readers to go around to read the meter, and always spend much money on traffic and labor.
