Electricity Consumption Meter FF LE-03MQ — Single-phase / Three-phase Bidirectional with Network Parameter Analysis

FF LE-03MQ is a bidirectional electricity consumption meter designed for both single-phase and three-phase installations. It registers active energy in forward and reverse directions and provides analysis of key network parameters, enabling accurate monitoring of consumption, generation feed-in and basic power quality diagnostics for residential, commercial and small renewable energy systems.

Advantages

The meter supports bidirectional measurement so it can track energy imported from the grid and energy exported back to the grid. It reports essential network parameters for each phase, enabling detection of imbalances and deviations in voltage and current. Compact design and compatibility with standard DIN-rail mounting make it suitable for integration into distribution boards, while clear numerical readouts and parameter outputs allow straightforward reading and data collection for billing or monitoring purposes.

Suitable for

• Single‑phase residential metering and monitoring
• Three‑phase small commercial installations
• Small photovoltaic or other distributed generation systems requiring export/import accounting
• Basic power quality checks and phase imbalance detection

When it may not be suitable

This meter is intended for consumption and export measurement and network parameter analysis at a practical, user level. It may not be suitable where advanced power quality analysis (such as harmonic spectrum beyond basic parameters), high-accuracy laboratory metrology, or high-voltage industrial systems are required. For installations needing certified revenue-grade metering with specific regulatory approvals, verify local compliance before selection.

Key specifications

• Measurement: bidirectional active energy (import and export)
• Supported connection: single-phase and three-phase configurations
• Measured parameters: voltage and current per phase, active power, power factor and energy totals
• Mounting: DIN-rail compatible enclosure for electrical distribution panels
• Display: numeric readout for energy and selectable network parameters
• Use case: suitable for residential, small commercial and small renewable generator integration

How to use

Install the FF LE-03MQ in the distribution board on a standard DIN rail and connect phase and neutral conductors according to the wiring diagram provided by the manufacturer. Ensure the meter is configured for the correct number of phases in the installation (single-phase or three-phase) and verify correct CT or direct connection type if applicable. Use the front display to read energy import and export totals and view instantaneous network parameters. For data collection, follow the manufacturer instructions to access any available output signals or communication ports if present.

What to consider before purchase

• Confirm whether your installation is single‑phase or three‑phase and select wiring accordingly
• Verify mounting space and DIN-rail compatibility in the distribution board
• Check required measurement accuracy and whether the meter meets local regulatory or billing requirements
• If exporting generation, ensure the meter supports bidirectional accounting in your grid/contract arrangement

Usage recommendations

Have the device installed and commissioned by a qualified electrician. Regularly record meter readings or integrate the meter with your monitoring system if communication options exist to track consumption and export trends over time.
