Abstract： A new Coriolis measure and control system of powder flow researched and developed independently by Beihang University based on Coriolis principle was introduced. The measure principle and general introduction of the system were given. The mechanical part of the measure system as well as detail hardware and software of the control meter were designed. The communication design of fieldbus based on Profibus–DP and the Ethernet was described. The application status and newly research of the measure and control system were given. The results show that the system runs stably and accurately, and reaches the initial design requirements.
