Abstract :
A distance measurement system using an ultrasonic transducer is described. The method is based on comparison of the unknown distance with a standard length in the same medium. The measurement made is independent of temperature, humidity, pressure, and any other atmospheric conditions. The proposed method claims improved performance and accuracy over the methods known so far. A resolution of 0.25 mm, with a maximum error of 0.5 percent, is obtained.
