Design and Research of Key Technology of Coriolis Flowmeter’s Signal Processing System

This paper innovatively presents DSP processorTMS320F28335 and CYCLONE series FPGA-EP3C16F484 as a dual-core processor to design Coriolis flowmeter’s signal processing system. This paper introduces key techniques of Coriolis flowmeter’s signal processing system in details from hardware to software, using phase difference based on DTFT with negative frequency and sliding DTFT to detect phase difference, then give then give Cumulative mass flow measurement results.
