Research on the Meter Coefficient and Simulation Analysis of a New Swirlmeter
The configuration of a new swirlmeter is designed. The hollow cylindric fluid axial-symmetrically in cylindric pipe is analyzed, and then the algebra expression of meter coefficient is deduced. An impeller of swirl generator attaching to a specimen of swirlmeter is designed according to the deducing process. Simulations and experiments test the method of measuring flowrate by measuring the rotation frequency of ball is feasible. Comparing the results of simulations and experiments with that of algebra expression derived from deducing in theory the maximal error is 7.8%. At last, the reasons resulting in the errors are discussed which the next researches will continue to minus the errors. The conclusion will be applied in designing the impeller of swirl generator and measuring the flow by the new swirlmeter.
