摘要：

This paper presents some considerations about uncertainty and noise related to ultrasonic transducers in time of flight estimation for wind speed measurement with pulsed transmission mode. Experimental results show the noise distribution in a measurement setup using ultrasonic transducers and the relation between signal to noise ratio, uncertainties and number of cycles used in pulsed transmission by transceiver. From these results, the project considerations for ultrasonic signals acquisition can be defined, such as number of cycles and uncertainty evaluation.
