Research of new ultrasonic domestic gas meter

摘要：

　　In recent years,with the rapid development of science and technology,the ultrasonic flowmeter has been widely applied.It measures the flow of liquid by using the liquid velocity information of the ultrasonic transmits in the liquid.The advantages of the meter are non-contact,no pressure loss,low cost,simple structure,wide measuring scope.In this paper,by absorbing and referring to the domestic and foreign advanced technology,the author developed an ultrasonic domestic gas meter based on transit-time difference method and MSP430.And it can measure fluid flow accurately.Experiments show that the system is stable and reliable,test data has good repeatability.The system lays a good foundation in developing the high-performance ultrasonic flowmeter in the future.
