With the market demand for energy meter function, the development of science and technology, energy meter in continuous innovation. 1881 according to the principle of electrolysis made energy meter, this kind of energy meter weighs tens of kilograms, very heavy, and no precision guarantee, but at that time is still as a major invention of science and technology. 1888 induction type energy meter (mechanical energy meter) was born, induction type energy meter structure is simple, safe operation, high cost, easy to mass production. In the 1960s, all electronic energy meters were introduced, and with the development of electronic technology, electronic energy meters have occupied the market with their absolute advantages, and have been upgraded and iterated, and are now the world of electronic energy meters.
Ordinary electronic energy meter: only the function of electricity measurement, ordinary counter energy meter, ordinary LCD energy meter.
Multi-functional meter: With the development of chip technology, the functions of energy meter are more and more, such as demand, reactive power, anti-tamper, prepaid, multi-tariff, event record, event alarm, load curve, communication, etc. Single-phase multi-functional meter and three-phase multi-functional meter are the mainstream.

Smart meters: the era of intelligent, informatization and digitalization of the IoT has come, and energy meters are also following the trend; on the basis of multi-functional meters, load control, two-way metering, bi-directional communication, etc. have been extended. In single-phase smart meter, three-phase smart meter research and development applications, communication technology has become the key; according to different use environment using different communication, RS485, PLC, Zigbee, LoRa, RF, GPRS, WiFine, WiFi, Ethernet, etc., the stability and reliability of communication is what each manufacturer is seeking.
As a electric energy meter manufacturer for nearly 30 years, Yongtailong, as a digital Power meter manufacturer,has been focusing on the R&D, producing and sales of electronic power meters. Under the guidance of product leading strategy, customized R&D is the strong point of Yongtailong, which is deeply recognized by customers.
