Secure Meters: Liberty 150

A smart metre is an electronic device that records data such as electric energy usage, voltage levels, current, and power factor. Smart metres transmit data to consumers for better understanding of their use habits, as well as to energy suppliers for system monitoring and customer billing. Smart metres often record energy in near real time and report on a regular basis at short intervals throughout the day.  Smart metres allow for bidirectional connection between the metre and the central system. AMI differs from AMR in that it allows for two-way communication between the metre and the supplier. Wireless communications from the metre to the network are possible, as are fixed cable connections such as power line carrier (PLC). Cellular communications, Wi-Fi (which is widely available), wireless ad hoc networks over Wi-Fi, wireless mesh networks, low power long-range wireless (LoRa), Wize (high radio penetration rate, open, using the frequency 169 MHz), ZigBee (low power, low data rate wireless), and Wi-SUN are all common wireless communication options (Smart Utility Networks). Secure Meters: Liberty 150 is a latest smart meter introduced by Secure company. You can contact us Bigwit Energy for more details on secure liberty 150 smart meters here.
