In order to solve and improve the measurement accuracy of ultrasonic flow sensor in unsteady flow condi-tions,the general regression neural network was introduced to obtain the flow sensor coefficient. And through the es-tablishment of the flow sensor coefficient model and the training of input samples,more accurate flow sensor coeffi-cients and higher measurement accuracy were obtained. So the feasibility of this method for the flow measurement in non-ideal flow field conditions by ultrasonic flow sensors had been verified,and the practical reference value of this method also had been reflected.
