(...) I cannot provide any comparison information because I think it would be improper of me to do so. I would like to set out a couple of technical details relating to distance measurement using ultrasonic techniques, since I have been involved in (...) (21 years ago, 18-Mar-04, to lugnet.robotics)

(...) How sensitive can you get this way? Specificly I'm thinking of having the sensor looking down a long "hallway" with airflow directed toward or away from the sensor (this too should result in a differing time-of-flight, yes?). (21 years ago, 6-Apr-04, to lugnet.robotics)

(...) Yes, this should work, but you won't be able to measure the direction of the wind, just it's velocity. But then this isn't different from the cross-wind situation either. Remember velocity=distance/time (v=d/t). The way to measure wind speed (...) (21 years ago, 6-Apr-04, to lugnet.robotics)
