The working Principle of High Sensitivity NYCSUL Ultrasonic Level Gauge Alarm Setting At Any Ponit

The working principle of the ultrasonic level gauge is that the ultrasonic transducer (probe) sends out a high-frequency pulsed sound wave when it encounters the surface of the measured material (material) and is reflected and folded back. The reflected echo is received by the transducer and converted into an electrical signal. The propagation time of the sound wave It is proportional to the distance from the sound wave to the surface of the object. The relationship between the sound wave transmission distance S, the sound speed C and the sound transmission time T can be expressed by the formula: S=C×T/2.
Because the transmitted ultrasonic pulse has a certain width, the reflected wave in a small area close to the transducer overlaps the transmitted wave, which cannot be identified and its distance value cannot be measured. This area is called the measurement dead zone. The size of the blind zone is related to the model of the ultrasonic level meter.
The probe part emits ultrasonic waves, the ultrasonic waves will be reflected when encountering a medium with a large difference in density from the air, and the reflected waves will be received by the probe part. The distance from the probe to the liquid (object) surface is proportional to the time passed by the ultrasonic wave:distance [m] = time x speed of sound/2 [m]
