Abstract :
It analyzed the measure elements of turbine flow meter roundly, and introduced a new type of turbine flowmeter based on HART Bus. The HART module consisted of AD421 and A5191. The circuit of HART bus module was showed in detail. The design scheme used MSP430 as the central controller and combined the software and hardware which achieved the flux compensates of oneself. It chose the other ultra-low-power external chips, achieved high precision and dependability, and reduced the system power.
