Meter class

Divided according to principles
1 electric meter is divided into induction and electronic two categories:
Induction meter uses the principle of electromagnetic induction voltage, current, phase shift for the magnetic moment, pushing aluminum disk rotating disc shaft (worm)

driven gear drive electromechanical counter drum turning, turning the process that is The amount of time cumulative process. Therefore, induction

Electric energy meter advantage is intuitive, dynamic continuous, power data is not lost.
Induction meter high requirements on the process, materials cover a wide range, metal, plastic, gems, glass, earth, etc., to which product related material standards

and requirements are clearly defined, with the cheap inferior materials instead of the standard affect the power specifications of the material is

Table One of the main problems of product quality, so like most commodities, low commodity prices will not have a good quality assurance.
Induction meter production process complicated, but already mature and stable, but also a comprehensive package tooling equipment. Production environment, temperature,

humidity and air purification higher degree. Over the past decade in Hangzhou, Ningbo, Wenzhou and other places formed the development of materials and energy meter

Parts market with considerable scale, the formation of large-scale production intensification distinctive Chinese characteristics, which is where the production of

electric energy meter has a price advantage in the market, one of the main factors.
Electronic energy meter using analog or digital circuits to get the product of voltage and current vectors, and then through analog or digital circuits metering

functions. Due to the application of digital technology, sharing billing meter, prepaid energy meter, energy meter multi-user, multi-

Meter have appeared, further meet the science of electricity, a reasonable demand for electricity.
Electronic energy meter in Jiangsu, Zhejiang, Shenzhen area high yield, which is concentrated in this area electronic products is the same, but also precisely because

of favorable market conditions, materials and components cause the formation of price competitiveness.
Currently Overall, induction meter, compared with the electronic energy meter, induction meter the quantity produced as much. However, production of electronic energy

meter has a clear upward trend.
2 Press the accuracy of measurement of electrical energy classification, generally one and two tables: one represents energy meter error is less than ± 1%; 2 level

representation energy meter error does not exceed ± 2%
3 Press Additional Functions division multiple rate meter, prepaid energy meter, energy meter multi-user, multi-function power meter, power meter, etc. carrier. Multi

-rate watt-hour meter or called timesharing energy meter, multi-rate table, commonly known as peak form, in recent years to adapt to TOU

The need to provide a means of measurement. It can be scheduled peaks and valleys, usually divided into segments, each measuring peak, trough, flat section of

electricity consumption, thus the different periods using different electricity tariffs, tariff regulation play a role in encouraging electricity customers

Adjust electricity load, peak load shifting, the rational use of power resources, to fully tap, supply, electrical equipment potential, is electronic or

electromechanical energy meter; commonly known as prepayment meter card table, with the IC card pre-electricity, the IC card inserted in the table can be controlled by

cost power, anti-

Only electricity arrears, is electronic or electromechanical energy meter; multi-user meter a meter for multiple users, separate billing for each user, so you can

achieve savings in resources, and facilitate management purposes, but also conducive to the remote Automatic Meter Reading, is electronic energy

Table; multifunction energy meter set number of functions in one, is the electronic energy meter; carrier energy meter using the power line carrier technology for

centralized remote automatic meter reading, an electronic energy meter.
