The study on Measurement Characteristics of fluidic flowmeters sensors with CFD

CFD technology is employed to simulate the fluidic flowmeters. A modified structure, that with double-target and polygonal surface, is proposed. The Measurement Characteristics are compared with the other two fluidic flowmeters, named in the paper meter with single-target, meter with double-target and straight surface. The flow fields are illustrated. The performance and the relationship between the flowrate and the oscillation frequency for each meter are obtained. Some useful theoretical information can be provided for the design and optimization of fluidic flowmeters in this work.
