Application of RFID Technology in Heat Meters

The application of RFID technology in heat meters is presented in this paper. Heat meters are terminal equipment in heat supply management system. By use of RFID technology in heat meters, the data can be exchanged between heat meters and heat supplying department by RF cards. The information can be transmitted in a non-contact way. In this way, the purpose of automatic identification can be achieved. A diagram and specific design method of heat meters based on RFID are also shown in the paper. By the proof of testing and practical application, it can be seen that the new type of heat meters can meet the demands of users. Compared with the ordinary heat meters, the new type of heat meters have the advantages of small in meter volume, high accuracy, no impact of water quality, good reliability and so on. This provides a firm material foundation for management information and intelligent management in heat metering.
