| Abstract: | Vortex flowmeter is a widely used hydro-vibration flowmeter. Its poor noise to signal ratio and anti-jamming ability, however, limit its application. The subject has made study in dual bluff body combination to consolidate the hydrodynamic vibration within the flowmeter. The optimum combination structure of the dual bluff body has been achieved by experiments. The results show that dual bluff body combination could strengthen the vibration and improve the noise-signal ratio of flowmeter. |
