| Abstract: | The basic structure and principle of a new type of target flowmeter based on differential capacitive structure were introduced.A secondary instrument was designed using MSP430f147 as Host Controller that achieved the functions of instantaneous flow measurement,cumulative flow rate measurement and real-time display by means of digital processing such as filtering,linear modification and density compensation.The experimental results show that this type of flowmeter have the characteristics of high sensitivity... |
