| Abstract: | The digital driving method which consists of frequency, phase and amplitude tracking based on DDS and MDAC is studied. A digital Coriolis mass flow transmitter is developed with TMS320F28335 chip. The driving technology is realized in real time. The gas-liquid two-phase flow-rate experiments are performed through connecting the transmitter with a CMF025 type Coriolis mass flow sensor. The results show that the transmitter can maintain the vibration of the flow tube and realize the flow measurement in two-phase condition. |
