Product description

Electricity consumption meter single-phase.
LE-01MR is a static (electronic) calibrated electricity meter of single-phase alternating current in a direct system. It is used for reading and recording of consumed electric energy and mains parameters with remote readout via a wired RS-485 network.


Measured values
Active power  - AE+ [kWh]                                    Active power - P[W]
Reactive energy - RE+ [kvarh]                              Reactive power - Q[var]
Phase voltage  - U [V]                                           Apparent power - P[VA]
Phase current  -  I [A]                                            Power factor - cosφ
Frequency  -  F [Hz]
Meter system temperature - T [°C]

Under the influence of flowing current and applied voltage, the LE meter accurately measures the amount of consumed electricity. Energy consumption is indicated by flashing LED (1000 pulses/kWh). In addition, the device measures the mains parameters and the temperature of its own system. The values are displayed cyclically on LCD display. Parameter changes every 3 seconds. Indicated values: active power (0.1 kWh); voltage (0.1V); current intensity (0.1A). The display is active if the meter power supply is on. If the power supply is off, user can preview the energy usage [kWh] for 30 seconds by pressing the PRESS key.
Communication with the meter working as a SLAVE is performed in accordance with Modbus RTU standard via RS-485 serial port. Converted registers values give results consistent with the indications on the meter display. Each indicator is identified by a unique address assigned by the user.



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.
