The meter provides 4-quadrant energy and power measurement as well as monitoring of many additional network parameters such as voltage, current, active power, reactive power, apparent power, frequency, power factor. The meter has additional, erasable active and reactive energy meters. It is also equipped with RS-485 communication interface with Modbus RTU protocol support for remote meter reading and configuration. The touch button located on the front panel of the meter allows you to select the displayed parameter and change the meter settings.
The backlit LCD display makes it easy to read the measured values. The parameter is changed by default every 5 seconds or at the frequency set by the user and manually, using the touch button on the front of the casing of the meter. The display is active when the indicator power is on.



The meter has sealable input and output terminal covers to prevent any attempts to bypass the meter.

The meter is marked with individual serial number allowing its unambiguous identification. The marking is laser engraved and cannot be removed.

Programs for remote reading of electricity meters
LE-01M, LE-01MP, LE-01MR, LE-03M, LE-03MP, LE-03M CT


The MeternetPRO application allows remote reading of states and indications of counters, multimeters, measuring transducers, expansion modules of input/output and other measuring devices communicating through Modbus RTU protocol. The exchange of data between devices and the application is executed through RS-485 or local area network (LAN). The application, along with the database is installed on a special MT-CPU-1 server, which operates in a local network. Software user interface is a web application (web site). Access to the application is executed through any web browser. In a LAN with a public IP address, you can configure the application and read the data over the Internet.


Subscription billing of electricity consumption module
Module of the subscription billing of the power consumption or other recorded incremental value, for example: water, heat, etc. It allows you to calculate the increases in the value in the designated billing periods (intervals). Cycles: monthly, weekly, daily, hourly. The module allows you to create multiple individual and parallel reports.
