The design principles of conversion circuit for intellect vortex flow-meter with MSP430 microcontroller used as the core was described in detail. The implementation plan of system development was confirmed based on the analyzing of the key technology of vortex flow-meter, which collected and processed the pulse signal from the pre-amplified circuit and sent to the module of D/A conversion converted into standard 4 ~ 40 mA output. The key of the design of hardware circuit and implementation of software was stated. The result tested and approved by the site shows that the technology index has met the design requirement with the character of reliability, which solves the problem of the large wastage of power and low stability. Its performance can be comparable with that of the same import products and its cost is much lower. It has a broad market prospect. |
