Realization of HART protocol in multi-variable vortex flowmeter Ma Yong-cheng Mo De-ju (Information Science and Technology Department, Beijing University of Chemical Technology Beijing, 100029) 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.
