| Abstract: | It is a developing tendency of Coriolis mass flowmeter that the digital methods are used to processe the sensor signals and drive the flow tubes. A synchronous modulation method is studied for processing sensor signals of Coriolis mass flowmeter. The algorithm is derived, its performance is analyzed, and computer simulations are carried out. The digital driving methods are studied, the performance of flow tubes in the outset of oscillation is improved by the digital control technique. And a digital driving scheme is presented. |
