The single phase metal base energy meter is a traditional electricity metering device, which was once widely used in residential households, small commercial shops, and low-power single-phase electrical scenarios. Characterized by its cast iron base and transparent glass cover, it belongs to the classic representative of early electricity metering equipment.

Core Advantages
1.Higher Power Bearing Capacity
It can stably power high-power devices such as air conditioners, electric water heaters, and commercial equipment without overheating or burnout.
2.Tunnel-type Terminal Blocks
Built-in thickened terminal posts made of copper, featuring excellent electrical conductivity and high-temperature resistance, as well as corrosion resistance and ductility.
Function and Features
-Measure active electric energy, do not need calibrate for long-term operation;
-Long service life, accessible 10 years;
-Sampling current at the same time between phase line and middle line, use the larger as valid sampling, abstraction-of-electricity prevention one fire one ground thoroughly;
-Adopt exclusive use LSl and SMT surface fixing technique, having advance technology and simple structure;
- Adopt the latest oversea electric energy special integration circuit, greatly improved dynamic working range of Meter,
-Have good mistake linearity in the range of 5%lb~lmax;
-Adopt high reliability and long life electronic component, so the Meter assume feature of high reliability and long life;
-Low self power consumption, mighty overload.
Core Structure
Iron Base: Made of high-quality cast iron material, it has strong load-bearing capacity and stability.The cast iron material has good impact resistance and tamper-proof performance, which can protect the internal parts from external damage
Glass Cover: Adopts high-transparency tempered glass, which has good light transmittance.
Working Principle
The iron-base glass-cover single-phase energy meter operates on the principle of electromagnetic induction: The current coil and voltage coil generate alternating magnetic fields respectively, which interact to form a rotating magnetic field that drives the aluminum disc to rotate. The disc's rotation speed is proportional to the active power of the circuit, and through a gear mechanism, it is converted into dial counting, ultimately displaying cumulative electricity consumption (unit: kWh).
