Quick door-to-door service, reasonable charges, remote meter reading and control in Qingdao

The earliest electric energy meter (also known as an electric meter) was made in 1881 based on the principle of electrolysis. Although each meter weighed tens of kilograms, was very bulky, and had no guarantee of accuracy, it was still regarded as a major invention in the scientific and technological field and was highly valued and praised by people. It was quickly adopted in engineering. With the development of science and technology, the discovery and application of alternating current in 1888 put forward new requirements for the development of electric energy meters. Through the efforts of scientists, induction type electric energy meters have been born. Due to its simple structure, safe operation, low cost, durability, ease of maintenance and mass production, induction energy meters have developed rapidly.
The production of AC induction energy meters in China began in the 1950s with the imitation of foreign energy meters. After more than 20 years of effort, the manufacturing of electric energy meters in China has reached a considerable level and scale. With the development of science and technology and the requirements for overload capacity and service life of AC induction energy meters. In the 1980s and 1990s, China began the research and production of long-life energy meters, mechatronics energy meters (semi electronic energy meters), fully electronic energy meters, multifunctional fully electronic energy meters, prepaid energy meters, multi rate energy meters, maximum demand meters, loss energy meters, etc. After 2000, these semi intelligent energy meters were widely used in household electricity, commercial electricity, and other fields.
