Single Phase Smart Electricity Meter L
Single Phase Smart Electricity Meter L
The intelligent multi-tariff single phase electronic meter is designed for use in smart electricity metering systems with remote collection of readings.
The embedded IoT communication module allows utilities to receive information automatically about active and reactive energy, generation and consumption, voltage quality, tampering incidents, magnet exposure and etc. via radio (RF434 or RF868) LPWAN, GSM or RS-485 technology.
The counter withstands magnetic fields of 500 mlT, and also records the date and time of exposure.
The meter will promptly transmit to the dispatcher information about the facts of opening the terminal cover or case, exposure to a magnet, electrical disturbance, attempts to handle an incorrect password, deviation of network parameters, overheating, etc.
Allows you to remotely disable defaulters. Relay triggering is configured depending on certain events.
Electricity consumption and other indicators recorded by the meter can be monitored remotely in your personal account in any place where there is Internet.
In addition to metering the current in the forward and reverse directions, the meter monitors and displays the network parameters, generation and consumption.
In the event of a power outage, data will not be lost thanks to non-volatile memory. And the operation of the calendar and display is provided by a built-in battery with a long service life.
