英文摘要：

In order to prompt the accuracy of Coriolis mass flowmeter, ameliorate the current digital signal processing method and accelerate the technology processing of homemade flowmeter, a mobile experiment platform is designed. The principle and correlative method are summarized, and the research trend of digital signal processing technology for Coriolis mass flowmeter is pointed out. Based on what have been done above, the requirement of the platform is analyzed; the main scheme, hardware frame, software flow and technology index are put forward, and the detailed design plan of data collection module which includes parts of PLC and NI9234 is expatiated. The preparatory test result is produced. The result shows the stability and validity of the experimental platform, which can meet the requirement of method research of corresponding digital signal processing for Coriolis mass flowmeter.
