The displacement cylinder suspended on the measuring spring is immersed in the liquid to be tested, and is subjected to upward buoyancy by Archimedes. Take a look at the Ultrasonic Level sensor working principle above. This water level controller will use two components the ultrasonic sensor and relay board. The distance for the motor to turn off and on needs to be specified. There is a special program that executes the sensor. The optical level sensor contains a near-infrared light-emitting diode and a photosensitive receiver. Instead of using the speed of sound to find the level, however, they use the speed of light (see Figure 9). When the defined filling level is reached, the buoyancy causes the magnet to activate the reed contacts. The liquid level in a tank (LT) can then be determined by subtracting distance (d) from the height of the radar level sensor (HT), i.e. Many liquid level sensors also include a protective shield to protect the magnet from turbulence or interference from direct contact with the liquid. it sends out the sound waves in the form of bursts in downward direction to the fluid in the tank under level measurement.
