Wenzhou Legy Electric Meter Technology Co., Ltd., established in 2002 in Wenzhou, China, is a professional manufacturer specializing in the research, development, production, and sales of precision electrical measurement instruments. As a trustworthy supplier, the company’s own factory produces high-accuracy Single Phase Energy Meters that serve as the cornerstone of fair billing and efficient energy management. Leveraging over two decades of industrial experience in electrical manufacturing, every meter is engineered with rigorous quality control, ISO9001 certification, and international safety approvals including CE, CB, and ROHS. We bring the same reliability and innovation that defined our electrical manufacturing legacy to modern power metering, providing customized solutions to the global residential, commercial, and industrial markets with high-performance products and professional services.
A single phase energy meter is an integrating instrument designed to measure and record the total electrical energy consumed by a load in a single-phase AC circuit over a specific period. It operates by continuously monitoring voltage and current, calculating instantaneous power, and integrating it over time to determine total energy consumption in kilowatt-hours (kWh). Belonging to the category of precision electrical measurement instruments, it is one of the most widely adopted solutions for residential and small commercial power systems, effectively ensuring accurate billing and supporting demand-side energy management.
Single Phase Energy Meter is built with a dedicated electronic energy measurement chip and SMT manufacturing process, ensuring stable and accurate metering without mechanical wear; Class 1.0 accuracy with a start-up current of 0.004Ib to capture low-load consumption reliably.
Features a 6+1 digit LCD screen with clear kWh readout and power indicator light; non-volatile memory retains cumulative energy data for ≥10 years, with no complex menus or remote functions for straightforward operation.
Flame-retardant PC housing with UL94V-0 rating, electronic circuitry with overcurrent and overvoltage protection; IP51 protection for indoor use, operating temperature -25°C to 55°C, suitable for typical residential environments.
Standard DIN-rail or wall-mount design with pre-wired terminals, no special tools or configuration required; compatible with common residential distribution boxes, installable by licensed electricians in under 10 minutes.
Meets IEC 62053-21 and national electronic energy meter standards, with CE, ROHS, and local safety certifications; focused on reliable basic electronic metering for residential billing without smart grid or IoT features.
Utilizes a dedicated electronic measurement chip with SMT manufacturing, eliminating mechanical wear and ensuring consistent accuracy over time without the need for periodic recalibration.
Solid-state electronic design with no moving parts reduces failure rates and extends service life to over 10 years, minimizing replacement and maintenance costs for residential and small commercial users.
Focuses on core metering functionality without unnecessary smart features, offering a lower upfront cost while meeting all basic billing and compliance requirements for residential and small commercial applications.
Clear LCD display with straightforward kWh readout and no complex menus, allowing utility personnel and homeowners to easily read and record energy consumption without specialized training or equipment.
Built-in overcurrent and overvoltage protection circuits combined with flame-retardant PC housing ensure safe operation under normal residential electrical conditions, preventing damage from common power fluctuations.
Single Phase Energy Meter is installed at the main electrical entry to measure total household energy consumption for utility billing; electronic design with no mechanical wear ensures long-term accuracy and reduces maintenance needs for homeowners and landlords.
Used for individual unit metering in multi-tenant buildings, providing clear and accurate electronic billing for tenants without the need for remote monitoring or complex management systems.
Measures energy consumption for individual businesses in commercial complexes with electronic accuracy, supporting fair cost allocation without unnecessary smart features that increase cost.
Installed to track energy usage for individual workspaces with reliable electronic metering, providing accurate billing data for property management without remote access or advanced analytics.
Replaces aging mechanical meters with standard electronic models for improved accuracy and durability, without the need for IoT upgrades or smart grid integration in aging residential complexes.
Provides reliable electronic energy measurement for temporary power supply with simple installation and no complex configuration, suitable for short-term use with basic billing requirements.
A: No, this is a standard electronic single phase energy meter designed for basic billing purposes only. It does not have remote reading, smart home integration, or IoT features. It is intended for manual reading by utility personnel or homeowners, providing reliable and accurate electronic energy measurement without additional complexity.
A: The meter features a standard DIN-rail or wall-mount design with pre-wired terminals, requiring no special tools or configuration.
