3-phase electric energy meter LE-03MW
Product description:
The 3-phase energy consumption meter LE-03MW is an electronic and tariff device. It allows you to measure energy flow in two directions. It is designed to measure energy consumption in a direct system. Compliance with the MID directive.
The 3-phase energy consumption meter LE-03MW has a built-in real-time clock enabling measurement of electricity consumption divided into different tariff zones. It is equipped with RS-485 communication interfaces with the Modbus RTU protocol and an optical port compliant with the EN62056 (IEC1107) standard, which enables remote reading and remote configuration of the meter.
The RS-485 serial port and the implemented MODBUS RTU communication protocol allow the indicator to be used in remote data reading networks.
Electricity meter remote reading via RS-485

MeternetPRO – remote reading of the electricity consumption meter
The MeternetPRO program enables remote reading of the states and indications of meters, multimeters, measuring transducers, input/output expansion modules and other measuring devices communicating in accordance with the Modbus RTU protocol. The application is an integral part of Excel. The read data is presented in the program table. Data can be freely shaped according to the program functions of the spreadsheet. Data exchange between devices and the application is carried out via the RS-485 network or local LAN network. The program and the database are installed on a special MT-CPU-1 server that operates in the local network. The program user interface is a web application (website). Access to the program is through any web browser. In the case of a LAN with a public IP address, it is possible to configure the program operation and read data via the Internet.
Subscriber settlement module for electricity consumption.
Subscriber settlement module for electricity consumption or other recorded increasing values, e.g. water consumption, heat consumption, etc. Allows for the calculation of value increases in designated billing periods (time intervals). Cycles: monthly, weekly, daily, hourly. The module allows you to create many individual and parallel reports.
