【Abstract】 On the basis of traditional vortex flowmeter,a multi-variable vortex flowmeter based on HART communication protocol is designed. The criterion of HART protocol is introduced, and the design method of software and hardware is described for implementing HART protocol communication in multi-variable vortex flowmeter. The structure of system and partial circuit of hardware is present.更多还原
