| Abstract: | In this paper,the core of the technology is discussed ,which includes HART communication protocol,measurement methods and computation for storage tanks.HART communication protocol is applied in the system.The HART protocol provides a uniquely backward compatible solution for smart instrument communication as both 4-20mA analog and digital communication signals are transmitted simultaneously on the same wiring.HART protocol is illustrated and the operational principles of hardware and software of the Processor for Tank Farm are described. |
