Single-phase analog electricity meter Virone EM-8 – single-phase energy meter, mechanical display

Single-phase analog electricity meter Virone EM-8 is a mechanical energy meter intended to measure active energy consumption in single-phase household and small commercial installations. The device provides a cumulative mechanical (analog) kWh register, a sturdy housing with fixed-installation terminals, and a simple construction that does not require a separate power supply for internal electronics. The Virone EM-8 is suitable for basic measurement and billing where a reliable, maintenance-light mechanical counter is preferred.

Advantages

The meter offers straightforward, passive operation with a visible mechanical register that records cumulative kilowatt-hours without the need for batteries or electronic displays. Its robust enclosure and conventional terminal layout support long-term fixed installation in residential or small business distribution boards. The simplicity of the mechanical counter reduces the risk of software faults and makes readings easy to verify visually.

Suitable for

• Monitoring single-phase household electricity consumption
• Basic billing or submetering in small shops and offices
• Use in properties where a non-electronic mechanical register is required
• Replacement of older mechanical single-phase meters

Key specifications

• Type: single-phase mechanical energy meter for active energy (kWh)
• Display: mechanical analog cumulative kWh register
• Installation: fixed installation with screw terminals
• Measuring range: suitable for typical household single-phase voltage and current ranges
• Construction: sealed robust housing designed for distribution board mounting

How to use

Install the meter on a dedicated DIN rail or mounting surface in the consumer unit according to local wiring regulations, ensuring correct phase and neutral connections to the marked terminals. After secure mechanical and electrical connection by a qualified electrician, the mechanical register will begin recording accumulated energy consumption automatically when the circuit is energized. Read the cumulative kWh directly from the analog display for billing or monitoring purposes; record readings at regular intervals for usage tracking.

Usage recommendations

Have installation and any wiring performed by a qualified electrician to comply with local safety and metering regulations. Periodically check terminal tightness and the integrity of the housing seal. Use the mechanical kWh reading as the verified consumption value for billing; if remote reading or advanced features are required, consider an electronic meter designed for those functions.
