| Abstract: | Fieldbus is the crucial technology of the feature control system, fieldbus based multivariable flowmeter is the main intelligent device of fieldbus control system. This article discussed about the massive flow measurement of fluid,which is extensively used in process industry, developed the HART based multivariable flowmeter, fulfilled the intelligent integration of flow measurement. Industry application demonstrates that the multivariable flow transmitter can reduce the number of instruments and wiring, improve performance, and maximize digital advantages by providing users more information about the process, reflects the characters and advantages of fieldbus. |
