【Abstract】 In this paper,the performance of the turbine flowmeter under the pulsation flow is studied in theory.The theoretical relationship among the angle acceleration,the pulsation amplitude and the pulsation frequency is given by using a kind of mathematical model for turbine flow transducer.The flowmeter errors in the pulsatoin are calculated by computer programming when the pulsation amplitude and the pulsation frequency are changed.The data show and verify the error rules of the turbine flowmeter in pulsation.更多还原
