Classical ultrasonic echo analysis. The ultrasonic transducer to emit ultrasonic pulse meets the medium surface is reflected back echo is received by the same transducer and converted into electrical signals. The ultrasonic pulse in acoustic velocity, emitted from the ultrasonic wave to the received time interval and transducer echo to the measured dielectric surface is proportional to the distance. So the ultrasonic signal returned from the surface by measuring and analyzing the time difference can be calculated to surface distance sensor. Since the launch of the ultrasonic pulse with a certain width, the distance of reflection waves small region near the transducer and transmitted wave overlap, unable to identify, cannot measure the distance value. This area is called the blind area. We use intelligent transmitting pulse width adjustment technology, according to the received reflected wave signal intensity automatically adjusts the pulse width of the emission, which can adjust the measuring blind area size, the instrument can work in a smaller area.
