Description

1. Working Principle
Based on the principle that sound measures the distance. When the ultrasonic pulse radiated by the probe meets the surface of the medium measured, it will be reflected into four waves. Then the probe will receive the reflected wave and the time difference will be calculated through circuit analysis and transformed into electrical signal, in this way, the distance between the probe and medium measured(the height of the medium) will be calculated.
