Classicalultrasonic echo analysis. The ultrasonic transducer sends out the ultrasonicpulse to be reflected by the surface of the measured medium, and the reflectedecho is received by the same transducer and converted into an electricalsignal. The ultrasonic pulse travels at the speed of sound waves, which isproportional to the distance between the ultrasonic wave and the received echo.Therefore, the distance between the sensor and the liquid surface can becalculated by measuring and analyzing the time difference of the ultrasonicsignal returned from the liquid level. Since the launch of the ultrasonic pulsewith a certain width, the distance of reflection waves small region near thetransducer and transmitted wave overlap, unable to identify, cannot measure thedistance value. This area is called the blind area. We use intelligenttransmitting pulse width adjustment technology, according to the receivedreflected wave signal intensity automatically adjusts the pulse width of theemission, which can adjust the measuring blind area size, the instrument canwork in a smaller area.
