Measure principle of transit-time ultrasonic flowmeter was analyzed,flow characteristic was simulated based on Fluent software. The flow distributing and influence of different structure parameters on flowmeter performance were discussed. The simulation result is consistent with the practice,and it is helpful for structure optimization of flowmeter.
