    ultrasonic oxygen sensor

    keerthishree

      hi i am trying to design ultrasonic oxygen sensor in which transducer are placed in opposite directions in a tube know i has to measure the velocity by measuring the time taken to reach the signal from transmitter to the receiver but while measuring time using arduino it gives less time practically comparing to the theoretical.

       

      Please let me know what may be the problem
