Mechanical meter uses a magnetic field to rotate the turntable was born moment count metering gear drive. There is an electronic and mechanical metering combination meter, but increase the number of turns in the infrared sensor count turntable on the basis of mechanical, LED display, and set the time measurement, and other parameters measured in the microprocessor, may be data output function. Full electronic meter voltage and current sampling all digital, more accurate power meter is installed, can be measured phase voltage, current, reactive power, active power meter, time measurement, and other data, and even remote data transmission. Manufacturer is a lot of anti-tamper meter, such as the XJ, rich with Beijing, Beijing Fu Ming, Beijing Bona, Shanghai Huali, and so a lot of home, so to speak, there are more than 30 light Beijing. 220V single-phase meter, meter installation was divided into many projects, such as electronic table 1. The most common is the DDS type, generally have a number in the back of the model, such as DDS123, then the DDS is a single-phase electronic power table 123 is a manufacturer code number. 2. The single-phase electronic prepayment meter DDSY ... 3. Single-phase electronic prepayment meter DDSIY carrier single-phase multi-rate electronic energy meter, DDSF 4. prepaid multi-rate single-phase electronic energy meter 5. Single DDSFY remote carrier phase electronic energy meter DDZY. . . . And so on. . . _ _ Meter metering meter by meter Winbond Winbond Power Technology Co., Ltd. Winbond Power Technology Co., Ltd.
